Clean and sweet

When parents refer to home, I will think of there, where local customs and practices, and think think of my grandparents home, think of the courtyard I grew up in the city, fifty years back to four or five the home, but, each to have different feelings! But first give me the deepest impression, I still clearly remember everything ... ...

It is a small town in southwestern Henan, 涊栱厝俥where beautiful scenery, folk customs are simple, because be located in a mountainous area, the economy is less developed! My home in the county! The courtyard is faced south, when you walk into the door when, first, of greet is a pomegranate tree, the tree node is full of yellow pomegranate; North and West are all of the same colour brick big tile-roofed house! North of the house is on the west wing, is, their structures are two bedroom, middle living room; yard is spacious, at its center is an apple tree, the green apple on the tree swing back and forth, tree hem a table, the table with a few small chair; from real teens meters is a well, wellhead cover covers, which also pressing a piece of white stone, water stirring pulley rope tightly wrapped with;?? next to the water well is the kitchen; the back yard is two persimmons tree; a tree already laden with fruit! Persimmon tree is a tree, a tree full of dates let person be unable to hide one's greed! Out of the back door, there is a two, three hundred square yard, back yard is full of peach, peach was, hang full branch! This is my memory of hometown courtyard!

I remember it was a summer, I was only seven or eight years old, follow father back in my hometown! We pass a night road bumps, my father took me to a strange place, pointing to a tall tower said:" their home, is it!" Father readily opened unlatched the door, we just walked in the door, around the feet grandma was trembling was greeted, face was wreathed in smiles, looking at me, music and not on the mouth, directed at the real shouted:" Fang came back!" See Grandpa from the house walked walked out, look at me, Le goatee a Alice a curling, rush to the apple tree, picking a few apples to me, and he took pole to date jujube under, also go to the backyard to pick peaches, not for a while, I table in front of piles fruit ... Because of father's brother. Few people work outside the home, only grandpa and grandma's life, I come to you to add joy to me, they are a favourite with. This is the first time I saw my grandpa, grandma at the scene!

In the old days, the day I am lying in the grandfather 's back, going to pick apples, peaches to eat! Also to the backyard to catch insects in the garden play! In the evening, my grandpa will move out of bamboo bed in the yard, let me lie in the shade, she would take a palm-leaf fan to catch mosquitoes, every night I was in sound sleep" cicada" in the quiet night, occasionally hear one or two insects! Silent night, occasionally see the tiny spots of light! Now think of that kind of mood is very comfortable! I miss my hometown at night!


I feel very sad to see

Should have this impression, at a downtown area or a busy time, always there are a few people, ragged clothes and the bustling scene be misfits. They are -- a beggar.

The mention of the word, maybe there will be a trace of sympathy, pity, or add some hate. For them, I do not have much feeling to describe them, but in a time of a place to meet one of these people, will suddenly feel so pain, sad.

For the young beggar, metropolitan a contemptuous disregard. Just imagine, young, what can not feed themselves, it is necessary to do this for life? But for the very small children and the elderly, cannot ignore. The child is still small, no ability to feed himself, what things can not handle. Society could not care for them, and they go to other place to roam. Encountered well-meaning, tube for a full meal is very good; meet unsympathetic, even an insult or ... ... In this environment, the children grow up, one can imagine the psychological pain. If encounter what goes wrong, some of them will be very much even rush into danger. Imagine your children or relatives of the children living here, would you blame others have no sympathy? A little to see these children, must not pretended not to see, to them, is a love and hate.

 

I laugh or cry

A season of flowers, a season of flowers. Soon, prosperous memory is gone! The withered petals who is magnificent burial clothes? Along the way, the way, the long, who knows? Along the way, the acid, sweet, bitter experience, spicy, who knows? Only the person you see scenery of the side, but who can understand your inner pain! Perhaps some people will say that it is the memory of the youth! But at the same time, who is my everything fades? Once that" I was born to be useful, the key moments of significant magical powers!" Gallant youth has gone with the wind! Today, I also understand that a" short, favors Bo Yutian!" Perhaps you as I compose the funeral song of youth, bury the dead memories. But who is in the middle of the night huddled in the corner alone secretly crying? Feelings of sadness, helplessness. Count ... ... Too long ... ... But who can understand? The cold stage, frozen two hot heart, we both know who will be who stays. Say goodbye but never to see, even if is a coincidence meeting will also try to disguise themselves at each other and said: " Oh, I'm very happy, you do not know? Maybe you are right!" Smile more than ever! Maybe I will owe you, perhaps this is fate between you and me! Once the spring to confidante old, people know flowers two.

To walk this road, red autumn leaves. But you know who gave this autumn red blood? Lived I much tenderness, now only a lonely hill! Is this why? Love! If sincere, people may experience. Love! If true, someone would care! This is I give" love" definition. But today I incapable of action! I began to doubt? Is that so? Sometimes, some people don't need to say good bye had left; some things not opening also understand; some way away will get shorter ... ...

A season of flowers, a season of flowers, flower and diffuse memory fragmentation. The green willow, red for half mask who anointed? Butterfly flower while drunk, and who hurt, the morning breeze and the lingering moon, always silent tears two row ... ... Turned a beautiful memory of the album, the former in hand. Birds have branches in pairs like Twitter, the birds in a single students mocked me! Have changed! The riverbank green willow, still waving in the wind in your elegant hair, that all over the mountains and plains camellia and who cry red eyes, you know? Maybe the previous marriage, perhaps next life reason, wrong in this life to meet, adds a fruitless.

Your mind, gray sky, rain, sprinkles, who knows this is my tears all over the sky! I put my hand to feel, the intention to contact, exactly how this is youth? Heart fretting, but the sentiment passed, also not, nor the past, everything not, could not pursue a ... ... May be" broken cloud, months; Zen, Buddha, broken, wake up ... ..." Walking alone in the breeze and drizzle, I wander, I think, can be ... ... Lost the past smile. Perceived not to the pear tree, I stopped, the past we have here have how much laughter, but, now I'm all alone. You say you like pear, yes, many colourful flowers. " A pear tree a creek, tonight I do not know is who?" Do not know where the poet so subtle mind! More beautiful! I don't know the care of pear white or pear reflected moonlight white. Now there is no moonlight anaphora, somehow Ewha are still as white? I don't know and don't know. Opportunities like this are rare let me out in the rain to see your white. Now you do not know is who? True to who? I wonder if you lonely? Think of me? I don't want to, but also not to care about many, hope you can have a good, turn, ray Leng Xiangyuan; evanescent snow depth, a shallow; the afterlife you cross me, please? Goodbye pear. Life gladly, water continuously, no matter where a is the matching of destiny ... ...

expert reminds

Ophthalmology expert reminds say, some sun hat with a bad film produced, do not possess professional fight ultraviolet function, at the same time, because of its material refractive medium transmittance difference, so that people in the visual feel fuzzy; plus the material density, so that the saw may be deformed, and then will increase, causes of visual fatigue. So, to wear the hat can not play the sunscreen, but also on human vision caused no small impact, even lead issue of road accident.

Generally speaking, the elderly to elect to wear the narrow side hat is appropriate, look simple, solemn; young men go out more, time is long, optional wearing a broad-brimmed straw hat; young woman skin delicate, elected to wear a cloth folding broadside cap, can increase the decorative beauty; pupils elect to wear green hat sun hat, can effectively protect the eyes; field operation construction workers, should wear a hat,contact plastic bag supplier to block the sun's ultraviolet rays, and can prevent the head from accidental injury. In short, no matter choose to wear which kind of hat, shall require its thin, cool features. Choose the visor, in addition to choose their own style, but also should pay attention to the effect of sunscreen, should choose a big hat brim, light; in addition, should also pay attention to the visor of sweat absorption and perspiration effect.

In the scorching sun, the hat can not only provide Ms Amy block ultraviolet, but also a variety of summer plastic image of beauty.

The summer sun hat

This summer for the visor material is rich and colorful, nylon, straw, hemp, gauze, cotton and so on, but the style is more be the most changeful, whether from the pattern color or style to give a person find everything fresh and new feeling. Here are several hat and matching for you as a reference:

In 1, sports cap

Summer sports cap to cotton or denim texture of the large front brim style is the most popular. The color to black and white color, also have a lot of beautiful prints to be suitable for young girls. The tall girl, wearing a sports cap has a valiant heroic spirit.

2, narrow brim round dome

Crown and a narrow brim has two main styles. The first is a cap cylinder is deep, narrow and rolled brim brim, near the decorative flower is gorgeous and exaggerated, with Georgette printed low-cut dress, especially thirty or forty time Hollywood star retro flavor. A narrow brim called fishing hat, with cotton, Hat Visor edge up, with a summer recreational sense.

In 3, a wide-brimmed hat

Hat is the usual sense of the ladies hat, the hat style is elegant and noble, so popular with white-collar miss love. It is generally made with ethereal lightness of linen, now there is also a lot of with special synthetic fabrics. This kind of hat brim width except outside, peak shape transformation is also a major bright spot. Whether lotus leaf edge or crimping or irregular in shape, have to give people a fresh and elegant feeling. This hat matches skirt bigger dress is perfect.


emulsion polymerization

Polystyrene plastics

( a ) brief introduction

Polystyrene is made by polymerization of styrene monomer from the linear structure of plastic. Its commercial name" benzene plastic", English abbreviate is PS. Synthesis of polystyrene is often used in bulk polymerization and emulsion polymerization.

1bulk polymerization

Styrene and inert gas, the temperature control in the 60- 90range, two benzoyl peroxide is used as a catalyst for the polymerization of resin, can be transparent block. The resin has high purity, good transparency and gloss.

The 2 emulsion method

Under the action of catalyst, styrene monomer emulsion in water temperature control in 80- 95DEG C. for polymerization, and then the polymer from the mother liquor in the separation, the treated by powder resin. The finished product is slightly higher than that of bulk polymerized resin with heat resistance, electrical insulation and transparency, but slightly worse.

( two) identifying characteristics

Hard and smooth surface, good transparency, strong color, bright color; texture crisp, low impact strength, easy to wear row, easily broken; percussion, sound is ringing,contact plastic bag supplier kinked easily broken; relative density is greater than l, slightly sink in the water.

( three) combustion phenomena

Good combustion performance, flammable, fire away after the burn, and styrene odour release. The flame was yellow, black smoke when burning, blistering softening.

( four) performance

Structure of polystyrene type is a linear structure, but the molecular chains of carbon atoms has a continuous interval large phenyl group, the structure of the decision of the special properties of polystyrene.

1 texture rigidity, impact strength is low; random configuration of polystyrene gloss, transmittance, color is good.

2 softening temperature of 80 degrees,80 degrees below it is as hard as glass solid, at 80 degrees C above becomes softer objects with similar properties, rubber, should avoid the use of high temperature.

3, forming a good performance, in the temperature range of use, product shrinkage deformation of small, stable size; good water resistance, chemical stability decreases with the increase of temperature; the concentration of inorganic acid, organic acid, salt solution and alkali, alcohol, vegetable oil has better resistance, in the sun for a long time placed will gradually turn yellow, devitrification and crack phenomenon.

4contact with oil, pest control agents often appear crack, discoloration and sticky melting phenomenon, in the light, oxygen, under the action of heat aging, yellow.

5easily soluble in chloroform, methylene chloride, toluene, acetic ester and other organic solvents, the custody of all and the solvent exposure.


therapeutic role

 Several treatment of hypertension of fruit and tea

Commonly used in the treatment of hypertensive disease fruit has the following kinds:

In 1, Orange: contains a lot of vitamin C, glucose and citrate in more than 10 kinds of nutrients. On chronic hepatitis caused by hypertension, eat tangerine can enhance liver detoxification, accelerate the conversion of cholesterol, prevent arteriosclerosis. After dinner to eat an orange, can increase appetite, eliminating hypertension caused by disorders of digestive function.

In 2, apple: containing malic acid, citron acid, vitamin A, with B, C and so on more than 10kinds of nutrients. Often eat apples can improve the hardening of the arteries, in recent years, studies have shown, eat more apples are good for halophilic excessive hypertension patients.

3, banana: containing starch, pectin, vitamins A, B. C and other substances. Can, diuretic Qingre Jiangya hangover, prevent hypertension caused by cerebral hemorrhage and stroke, available banana peel or fruit stalk30 to60 grams, Jiantang clothes. Conditional desirable amount of banana flower decoction, curative effect is good.

4, water chestnuts: containing crude protein, calcium, phosphorus, iron, vitamin C and other seven kinds of nutrients. Fresh water chestnut ( wash), jellyfish ( from30- 60 grams of salt ), soup, on3 times service, have good antihypertensive and expectorant effects.

In 5, hawthorn: can dilate blood vessels, lower blood pressure, reduce cholesterol. Hawthorn10( selection of fresh goods for good ), mashed with sugar30 grams, decoct with water, has a good buck, stomachic Xiaoji role.

Chinese tea drinking also has auxiliary therapeutic role in hypertension:

1: hawthorn, hawthorn tea ingredients can promote digestion, reduce blood fat, dilation of blood vessels, reduce blood pressure, each with 1 to2water, tea drinking.

2, Chinese wolfberry medlar tea: in addition to lower blood pressure, cholesterol and prevent atherosclerosis, and tonifying the liver and kidney, improving eyesight and moistening dryness. General and daily dosage of 9grams, can take.

3, chrysanthemum tea: the chrysanthemum is chamomile, its taste is not bitter, Hangzhou white chrysanthemum or feverfew is better, each with 3grams of tea take1,3 times a day. Chrysanthemum and honeysuckle, licorice can also be used with fried, tea drinking, has Pinggan Mingmu, heat clearing and detoxifying.

4: the tree, Sophora tea buds dried with boiling water, soak offspring of tea drinking, treatment of hypertension KGB special effects. At the same time, Huaihua also a vasoconstrictor, hemostatic efficacy.

5: lotus leaf, lotus leaf tea infusions and decoctions can dilate blood, heat Jieshu, the blood pressure-lowering effect. Lotus leaf or slimming medicine. Family school commonly used method is: use of fresh lotus half a Major-General, shredding, suitable amount of water, decocting later and cool, and tea drinking.

In 6, lotus tea: lotus is lotus middle green germ, its very bitter taste. Take the lotus12 grams, boiling water on behalf of tea brewing, in addition to lower blood pressure, but also heat, calming, strong heart.

7, cassia seed tea : semen with hypotensive effect, with 15 to20 grams of cassia seed soaked in water, tea drinking, daily times, effect is good.

filter capacitor

The switching power supply, as the name implies, is there a door, a door through a closed power supply, power supply is stopped by the door, so what is it, switching power supply in some adopts the controllable silicon, or by the switch tube, the two components with similar performance, is to rely on base, ( switch ) control pole ( SCR ) plus pulse signals to complete the turn-on and turn-off, pulse signal is a half weeks of arrival, control electrode voltage increases, the switch tube or a controlled silicon is conducted by 220V, rectifier, filter output 300V voltage is conducted through the switch, transformer to the secondary, and through the transformation ratio of the the voltage is increased or decreased, for each circuit.dvb receivers Oscillation pulsed negative half period arrival, power adjust tube base, or to the control electrode of the controlled silicon voltage is lower than the original set voltage, the power adjust tube cutoff, 300V power supply is shut off, switch the transformer secondary no voltage, then the circuit required working voltage on the road, secondary rectified filter capacitor discharge maintain wedding.

Up until the time of the next pulse cycle positive half cycle signal arrives, repeat the last process. The switch transformer is the transformer, because his work frequency is higher than that of 50HZ low frequency. Then push the switch tube or SCR pulse to obtain it, it would be necessary for a oscillation circuit generates, we know, crystals of the three transistor has a characteristic, is the base to emitter voltage is 0.65-0.7V amplification, 0.7V above is saturated conduction state, - 0.1V - - 0.3V work in the oscillatory state, then the the working point after a good tune, rely on deep negative feedback to generate negative pressure, so that the oscillation tube vibration, oscillation frequency by the tube base of capacitor charging and discharging the length of time to decide, oscillation frequency high output pulse amplitude is large, it is small, this decided the power adjust tube output voltage size physiotherapy.

Then the transformer secondary output voltage to voltage, generally in the switch transformer, single winding a coil group, at the upper end of the voltage obtained by rectifying and filtering, as a reference voltage, and then through a photoelectric coupler, the reference voltage to return the oscillation tube base, to adjust the vibration frequency, if the secondary of the transformer voltage increases, the sampling coil output voltage is also increased by a photoelectric coupler, obtained positive feedback voltage increases, the voltage applied to the oscillation tube base, makes the oscillation frequency is reduced, to stabilize the secondary output voltage stability, very fine work needn't fine said, also need not know as fine, so that high power voltage by transformer switch transfer, and later separated, return the sampling voltage by optical transfer and grade separated, so the former class of electric voltage, was associated with later stage separation, this is called cold plate, is safe, before the power supply transformer is independent, this is called switching power supply agnesf.


eating supper

 A healthy diet to lose weight 5 principles

[review] there are many kinds of methods to lose weight, diet and exercise two method is the most direct and efficient, which can control the diet and physical energy intake, relationship to body fat burning, weight loss is the fundamental one.

But blindly pursue the effect of weight loss, blind excessive dieting, can cause gastrointestinal disease, endocrine disorders, psychological burden is increased, run counter to one's desire, harm to health. How health management diet structure, choose suitable weight loss diet, let us refer to the Japanese IDA type diet, let you lose any door!

The principle of a choice edible soup & Salad

Weight loss diet principle, is a choice edible salad & pickles and other raw vegetables. Raw vegetables contain helpful body slimming important slimming" enzyme", in which amino acids, vitamin, help digestion and metabolism of the body of essential nutrients.

Vegetables contain plant fiber, can slow down the body of the sugar and fat absorption. So once the feeling of hunger, the best choice is to vegetables!

Secondly, recommended food miso soup, hot sauce, raising body temperature, strengthen metabolism. The staple drink before dinner, can promote digestion, and is easy to produce satiety, indirect control diet.

Principle two maintain a pleasant mood to enjoy the food

Research shows that, the mood is the important factor affecting body weight, MM are in the process of weight loss, often to diet, much like eating food can't touch, forced to choose light vegetarian food, long-term appetite is not satisfied, can produce anxiety and boredom, indirect impression to the digestion of food and absorption. In order to better and more consistent weight loss diet a protracted war, to adjust their own psychological, bring happiness to eat, so that the endocrine and digestive system subject to mood effects will increase the rate of fat burning, eating can also be thin.

Rule three if you want to eat pork, on the choice of red meat

Like meat MM, can choose a fleshy red meat, red meat contains promote fat burning ingredients, mutton, beef, pork or in sequence contains rich fat burning material, which is not in the chicken. Pork flavor to light and salt, at the same time with a variety of vegetables, edible, can promote gastrointestinal digestive peristalsis, relieve oily meat. While paying attention to intake, not excessive, according to their own exercise considerations, to avoid energy excess fat storage.

Principle four weight loss can also eat rice

Rice as carbohydrates, the body into sugar, stored as fat in vivo, so weight loss of MM will choose the rice shield. In fact, it is unhealthy, long-term edible rice, will cause the body to sugar by the proliferation of intestinal bacteria reduce intestinal homeostasis, break, cause disease. In fact, weight loss are the natural enemies of wheat flour. Wheat flour can make the body cold, easily lead to obesity, the same food, avoid the selection of cakes and bread, rice and convenience is more healthy.

Rule five if a late-night eating, the very next day breakfast choice of water & Fruit

If the night eating supper, in order to ensure energy uptake equilibrium, the very next day breakfast diet content regulation is necessary. At noon as excretion and body cleaning time, breakfast and drinking water at room temperature with a cup of 1 kinds of fruit ( using a single hand can load rate is better ). The fruit is rich in vitamins, help metabolism enzymes, the diuretic effect of calcium and other minerals, can effectively help the body toxins and waste discharge, one day, can also choose the free time drinking a cup of fresh fruit juice, to stomach proper rest, healthy weight loss double bumper harvest.

voice transmission

DTX ( discontinuous transmission ) is a method for optimizing wireless voice communication system efficiency method, this method in the absence of speech input moment closure mobile or portable telephone. The typical 2 way call, each party talk time is slightly less than half of the total time, so if the transmitter only in the presence of speech input when open, the phone work duty ratio can be less than 50%.

This situation can save the energy of the battery, dvb receivers reduce the transmitter element 's work burden, make more idle channel, to allow the system to use the idle bandwidth with other signal sharing channel. DTX using voice activity detection ( VAD ) circuit, the wireless transmitter is sometimes referred to as the work of voice transmission ( VOX ).

3GPP also regulate the FDD terminal using only 60MHz bandwidth, duplex interval of 190MHz: 2110MHz-2170MHz used in mobile RX, 1920MHz-1980MHz for mobile TX.

The principle of CDMA

In the discussion of WCDMA transmitter before, this part CDMA of the principle of simple overview. CDMA system using signal extension mode called " direct sequence spread way". In order to expand the signal, the CDMA system with a unique, called extended codes multiplied by the unmodulated baseband data, code contains a certain number of chips.

The extended data is modulated onto a carrier for transmission, modulated carrier bandwidth by spread spectrum coding chip rate direct effect. WCDMA uses 3.84MHz chip rate, have very wide bandwidth of emission spectrum, so the use of the word" broadband".

In order to extract the original information, CDMA receiver demodulates the information carrier and the use of the correlator (with the original transmitter spread-spectrum code ) to generate the desired signal ( DS ). Were extracted from the data through a narrow band bandpass filter according to the need for further processing.


Science research

Environmental science is the study of the physical, chemical, biological environment part three of the subjects. It provides a comprehensive, quantitative, and interdisciplinary approach to the study of environmental system. Because most environmental problems involving human activity, so the economic, legal and social science knowledge often also can be used in Environmental Science research. A study of the development of human society activity and environmental evolution of the interaction between, for human society and environment evolution, sustainable development means and methods of science.

Study of human living environment quality and its protection and improvement of the science.

Environmental science research environment,operable wall is take the human as the main body of the external world, i.e. the human survival and the development material conditions of the complex, including the natural environment and the social environment. The natural environment is directly or indirectly affect human, all natural substance and energy in general. Now most of the earth's surface with human intervention, the original natural environment is not much. Environmental science research by human beings in the natural environment social environment is the basis, through long-term conscious social labor creates artificial environment. It is the human material civilization and spiritual civilization development of the logo, and with the development of human society and constantly enrich and evolution.

Purpose

1 for the maintenance of environmental quality, develop a variety of environmental quality standard, pollutant discharge standards to provide a scientific basis.

2 for the establishment of the national environmental planning, environmental policy and environmental and resources protection legislation basis.

Survey

Environmental protection is the world people's common concern important social and economic problem, is also a science and technology in the field of major research topic. Environmental science is in the modern social economic and scientific development in the process of forming a comprehensive science. On the world

As a whole, environmental science become a scientific or nearly two, thirty years.

The environment is relative to the center of things. With a center object in relation to the surroundings, this is the environment. Environmental science research environment,operable partition is take the human as the main body of the external world, namely human ' survival and the development material conditions of the complex, including the natural environment and the social environment. The natural environment is directly or indirectly affect all human natural substance and energy in general. Now most of the earth's surface with human intervention, the original natural environment is not much.

Environmental science research by human beings in the natural environment social environment is the basis, through long-term conscious social labor creates artificial environment. It is the human material civilization and spiritual civilization development of the logo, and with the development of human society and constantly enrich and evolution. Environment having multiple levels, a variety of structures, can be used for a variety of division. According to the environmental factors can be divided into atmosphere, water, soil, biological environment; according to the scope of human activities can be divided into workshops, factories and mines, village, city, regional, global, space environment. Environmental science is the environment as a whole to conduct a comprehensive study of the.
