No matter is east or west, all treat purple color as the color that symbolizes the high identity.In the precious stone, only the amethyst can send out the purple ray of light of this kind of nobility.Someone says that in the nature, the most beautiful of purple is the purple light of amethyst.

Our country 《natural science digest 》medium say, the amethyst"the color is like grape, light Ying lovely", this kind of as the purple color of grape is in order to containing to little by little oxidize iron in the crystal to.

The amethyst is Sagittarius to guard stone and birthstone.I'm very happy, because next week I will be held the weddingcheap wedding dresses, I needcheap evening dresses, I at the moment of mood very excited!!!!!

The university Yi in 1st centry A.D. compares pigeon Lu in his huge Zhao 《natural science ambition 》in has "purple of the precious stone is Venus' eyes" a say.Is a lot of nations at the west, amethyst not only Be come to the stone of wine is embellished in the man of jewelry kimono decorate up, in the meantime still as the lucky precious stone of performing arts the houses, be subjected to special favor.

"Amethyst" one etymology from the honesty of Greece language, the meaning is "keep one's integrity, silt but don't dye".This etymology, until Middle Ages is all seen as the smoking ban and forbid the sign of wine.Today, the amethyst then is seen as the sign of "honesty", "purely true love".

Industrial frequency UPS and the difference between the high frequency UPS

Author: UPS power source: guangdong burke issued time: 2011-6-9 11:15:30

With the developing of the technology of UPS, many computers, power electronics field, new technology, new concepts to UPS industry. And the IT industry of other products, UPS and similar now former product compared, regardless of in the main performance, appearance, the size of the adaptability of the environment and reliability, have the significant progress, some indicators and even a qualitative leap, for medium and UPS is even more so.An Uninterruptible Power Supply or UPS, UPS Power Supply is one of the most cost-effective ways to provide clean high quality power without any break in supply.

At present more popular large and medium-sized UPS structure is usually two kinds, traditional double transform structure and new structure, both in the IGBT application field formed complementary pattern, the basic structure of traditional UPS (industrial frequency machine) as follows, basic structure: silicon controlled rectifier + battery direct dc bus + IGBT inverter + boost transformer



All new IGBT UPS structure (high frequency machine) as follows, basic structure: not accused of rectifier + DC/DC times pressure link + independent charger + inverter



As can be seen from the graph, industrial frequency machine and the concept of high frequency machine is mainly to the rectification in part, industrial frequency machine is controlled rectifying, traditional technology can be done best 12 pat rectification; And the high frequency machine rectification is diode rectifier is not in possession of the high frequency IGBT + (dc link. As for inverter is of high frequency IGBT inverter SPWM working way (except the thyristor inverter early work mode, has been eliminated UPS). In addition, the output transformer industrial frequency machine is essential, because its rectifier inverter, etc for bp-lowing link, link is therefore in the output side must have the boost as voltage transformer adjustment. And because of the high frequency machine DC/DC boost link, its output side with the boost links (unnecessary pressor transformer). Because of the components development, UPS as the main power UPS IGBT component technology, no matter more mature from capacity, structure, or reliability are is greatly raised, and the UPS digital degree further contributed to a new generation of large and medium-sized UPS structure by original industrial frequency machine is turning to high-frequency machine (as when SCR inverter power transistor is replaced by GTR, and after IGBT inverter to replace the same). UPS electrical structure of the direct effect is the most updated UPS host a decrease in the size of the, the weight of the drop, but more important is the price drops. The specific analysis of two UPS electrical principle and structure of the electrical properties:

Early main circuit structure and the large and medium-sized UPS silicon controlled rectifier the input of alternating current to direct current, the battery direct hanging in the dc bus, when the input utility the normal when, on the adjustment of silicon controlled rectifier battery, at the same time for GTR or IGBT structure of the bridge type inverter power supply, inverter dc to ac inverter, finally after the output transformer and filter the boost, provides pure ac output. From its structure, which can be seen from the rectifier (from the exchange into a dc) to (in from dc into inverter exchange) process, each link is will pressure link: silicon controlled rectifier is to provide constant dc voltage and take a way through rectifier (controlled rectifying the conduction angles adjust to fit the input voltage change, to ensure that the input voltage change of constant dc voltage rectifying output), because silicon controlled rectifier can only cut off part of the input electricity, so its constant output voltage is the price of the output voltage in less than the constant wave rectifier voltage of a numerical. And inverter link was also a step-down link, from controlled rectifying input to dc in through the inverter inverter out the process of the communication of the same is chopped practice, and the result is the same output voltage level down again. It is because of the above reasons, in such a structure of the UPS, must be measured in the output transformer, will join the boost the lower constant inverter output voltage to the output of the reasonable scope, and finally provides constant 220/380 V output.

2011 years after the last bus to set foot on 80 people say is a struggle of the moment. I calculate one carrying bricks climb step by step the turtle.

May it is a to cannes in busy, there was a huge event will be held here, from April 25 began to busy in the our life after only work as food and sleep. Also don't know is how to adhere to down I didn't for a day, according to the past my personality, would have to carry not to live. Perhaps is the age of the year become larger, more and more feeling the pressure on! In fact busy is also a kind of enjoyment, let me no time to worry too much, realistic, vanity, good, bad. To the world's too busy to worry is not, and my mind is how to put the task. As the event held our work gradually restored calm.

Time passed very quickly, and came to the June 1 children's day when the time is the most happy children the most pleasant, is also our most happiness because by this time we have seven days of vacation, (May 1 3 days in May for a week on a day of rest)

Finished busy day at leisure time to doing nothing, and every day that most of this time to sleep like a lazy into the old cat, narrowing her eyes when morning on until it was opened in the afternoon, after coming home first open a computer. In that first months on the computer already hates, and to see it is dizzy today opens the computer also not in the mood to play the game, and just see what dynamic space QQ, look at the news.

Have to share one show, "the naked zhou libo officer, nude of marriage, naked donate" laugh and after birth, some of which the feeling of many statements aftertaste letting a person also let people thinking. Marriage, a Shanghai man, in Shanghai suburbs that buy a house is mobile phone signals what suburb not too good areas, buy what room is common room 90 square meters of that kind of, need 1.85 million common decorate 15 w furniture appliances 5 w a car 10 w wedding and red envelopes in 215 w hypothesis to offset a family man with 40 w assetsopendoorm

A common Shanghai men take a above the average price of the Shanghai girl's purse, that boy is boy 8 w annual income is in the boy's purse sea or eat or drink for 21 years working hypothesis boy 30 years old married at the age of 51 can get married until the accounts of the pay off, say boy don not live at the age of 51 because don't eat not to drink a week and went away. At that time, I was amused by his words. But after see to a think not the taste, like to eat, first bite think g sour, sweet, good embellish, but a long time, the mouth sweet with the passage of time and in the disappearance of his mouth is the most left in only the endless sour se. The few words for mine feeling is so that, when after see facial expression of funny restore calm left only mind endless bitterness. 215 w ah what concept, I now can the rest of the money every year is less than 1 w, with the current income even if I become a ninja turtle will in 215, say that until then I the physical function of the all didn't, return how newly-married ah, that was the most suitable for me, I'm afraid of is the candle QingDeng, pickle. White porridge

In my friend in some income 10 w bought their own car, engaged, have a plenty of no skill oneself spend the money get married parents married, some even their parents have no skill to parents have no money to borrow money to marry. What kind of. I don't have a car and no room at the bank, more not RMB people like me, as made waves, dear to all of the said no one take reason. The material needs, let developed new century people to beautiful pursuit more and more high, the girls also more and more realistic. To love and to give up everything seems only to some plot. Inside TV A marriage only male prodigy appearance will be the world the approval, if the man have no skill but girl whose family is superior, can let a person gossiping, become a man after previous hot topic, the somebody else's mockery. The boy want to eat soft rice said, the toad eat swan.

I do not go to think my marriage, because I was afraid, afraid she look down on me, afraid I can't give him happy, and delayed her life. And I found that I have been integrated into this love group, now of the love is not really in love, is money in the collision, the demon drink wars, the more money than who is, who is more than earned vigorous. The real "peacock flies southeast", "the story of children in contemporary economy has not driven by.......

Most of the time I looked up at the sky fantasy of my future, out of the campus into society has nearly for 2 years, can barely feed themselves, the car house for me is a fantasy, a little small ticket and rising house prices as compared to a blip. Maybe one day I body protest strike, that some small insignificant ticket is not enough to pay the hospital. Some time ago to a college students is ill, two years of savings has finished, and to improve their hometown. 2 months many all didn't work (the event I give her a little help also collected 500 dollars, not a lot is not enough for the giants a meal for the meal, but to her was indeed a month's rent. All the new to go back to work and back to the starting point ah ~)

Remember small read a funny words about 80 now think true reality! 1 and when we read the primary school university is not money, when we read at the university of reading primary school is not money. 2 when we go to school when work is the distribution, when we graduation of time head also find a good job. 3 when we didn't work while you work house is distributed. When we take part in work, the house is can't afford it. Go to school at that time was the words is a joke in the mind a flash, now think is famous will now after 80 the distress of life covers precautions. If no parents support to a strange city, want to Ann a home too difficult, expensive rent every month, eat of wear of each month, with how much is left. Every year go home to honor your father and your parents buy gifts after the elders, the necessary to the younger generation some New Year's money. You and how much a year left.

Think about his path, look at your own two years insignificant struggle results. Heart is gloomy, I have no intelligent minds, also do not have strong body, in this materialized serious social, I may be a little turtle step by step to realize my dream know I quiet die, (if 2012 is really the end of the world I was free!)

Small power LED orders the glow-in-the-dark Fu applied big market
Know to all, compared with the Euro-American international market,LED Ceiling Light our country only Fu application market not yet start, be always placed in the not fiery appearance is not.The guo jia wants to cash in 2020 can the renewable energy has to compare to attain 20% commitment difficulties very greatly, but if choose big area to expand solar energy small power LED the street lamp is undoubtedly a shortcut that completes a target.Accompany with science and technology department"ten cities 10000" plans of push, in the future the LED light of the solar energy will already hope initiative to open domestic light Fu application market,LED flood light is the important branch of solar energy LED-small power LED lighting will also at light Fu application the market greatly have Be.Overrun small power LED hard nut to crack

Illuminates inside the profession in LED, LED's illuminating is praised as "the fourth generation illuminate light source" or"green light source".It is after"for the third time lighting revolution" of"the torch arrives oil lamp(candlelight)", "the oil lamp arrives an incandescent lamp(fluorescent lamp, economize on energy a light)" and"incandescent lamp arrive LED illuminate".For long time, Europe, the United States and day have been monopolizing LED the most decisive white light of profession, big power LED light hot balance, hold out for long time efficiently fluorescence powder etc. technique core, the local LED profession has been being placed in passive situation, the request of independent innovation product seems to be very urgently.Offend a lord at the LED profession when the direction all put to just develop to the great power technique the Texas virtuous energy subsidiary sword goes wide Feng-chose that the lord offends small power LED of hard nut to crack solar energy in the world a lighting product combine with one action yield success, LED spot light developed small power LED yield first river.According to understanding, that solar energy small power LED(0.06 Ws) product radiation conversion can reach to above 90% and spread calories less than 10% and have no Shuai to reduce for 2000 hours, the service life developed the economy energy effect to extreme achievement for more than longer than 50000 hours.

According to understanding, illuminate profession to subdivide in LED under, is divided into big power LED and small power LED.Usually under the circumstance, LED adopted illuminates above 90% currently, is the economy energy light that adopting the big power is a light source product.So-called big power LED is to point the single power that gives out light diode is bigger than to equal 1 W.Though the big power LED product compares a normal regulations lighting product economy energy, LED strip lightenvironmental protection,compares with small power LED product still slightly lousy on raising, many core technique Jis need breakthrough.According to understanding, the big power LED radiation converts not high, only about 50%-60%, a great deal of of the electric power depletion is in spreading a hot machine, this from need to install space radiator and then can see.In physically installing, big power LED also exists a many problem to need solution.

A great deal of research proves that illuminate a product in LED in, the single grain radiation power with tallest LED is or so for 0.06 Ws is the best, namely small power LED product.This hard nut to crack in the world drive Texas of a Guang Fu company overrun, virtuous energy subsidiary not only own small power LED complete intelligent property right, also solved to spread on the technique hot, light Shuai etc. key problem, become in the world rarely count own the production factory that small power LED illuminates patented product house.Now, the company's product technique has already developed to arrive the eighth generation.Develop a director general according to the virtuous source group beam treasure strong introduction:"The company is the ninth generation, the tenth generation product have already developed success as well, the product is placed in storage stage.Moreover, the company can combine to generate electricity in the solar energy moderate breezes, the usage of the solar energy system series products, such as water and solar energy car...etc. ascend to also all have a new research result."

The small power LED economy is worth of
Always, the flourishing guo jia illuminates industry to support strength to LED gradual enlargement.In 1998, Japan scolds 6,000,000,000 yen start"only plan in 21th century"s;The United States has invested "guo jia the semi-conductor illuminate a plan" of the USD 500,000,000 implementation since 2000;At the same year, the EU also declares a start"rainbow plan".Though the our country is in the LED industry start a little bit early, the zheng fu supports strength not enough, until releasing of science and technology department"ten cities ten thousand LED engineerings" document in 2009, local LED profession just welcome bigger development, everyplace competitively last LED horse's item.

Because the heat of local market goes up, LED profession but once sank into concept a full sky of fly, the weakness was prosperous, the innovation result was sparse to lack of trapped a bureau.The big power LED light of parts of gearings doesn't exert in the effect in the model item like person's idea, continuously appeared night to put out a light, short life span and bright degree not enough, maintain a difficulty to wait a problem.Originally had already installed the last solar energy light, afterwards changed to fire electricity's illuminating again, highlight economy energy the corrupt practice of stanza money seriously fought to install LED everywhere the confidence of the street lamp obstructed health that LED illuminates profession not rapid develop.

Worthy of rejoicing BE, the guo jia always will promote LED the profession development is strategy development direction.On May 19, is again sent out to develop second batches of experimental units model engineering by science and technology department, LED tube light continue explicit development LED the strategic direction of the industry, infused into new motive for LED industry development, the local market foreground is vast in the future.

Go out to play dress to pack how go together with to just show to lose
The clothes that make use of different style do to cover, at pay no attention of having a liking for have already lost 5000 grams of fellings and aim at different and"outstanding" part, 5000 gram invisible in the unconscious,cheap evening dresses however remind everyone, this kind of"Yan eye method" certainly just palliates of plan, make great effort to reduce weight be cure this good method.

1.the waist is thick

The fashionable dresses expert says:"If the waist is thick, don't have too many details the ho is between each waist, taylor made suits a kind of improvement way is to wear the connecting of quality softness body skirt."

The skirt usually has already started spreading out as follows in the chest, so this method will make the person can't see the waist real position, can really cover up belly to attain the effect of accepting the thick waist in the meantime, the choice connects dress skirt to seem to be lightness and all up and down feel good Be getting thinner.

2.big hip

The fashionable dresses expert suggests:" The attention concentration of the sense of vision is in the last body, a little more the detail put on the sexy neck.Wear a narrow body sweat dress, long coat and and knee skirt."In fact this way very shows results, so usually choose low chest blouse, augment a small trousers cover while also trying to wear trousers, may also with have already covered up a function.

3.the thigh is thick

"Elephant leg" is widespreadly the problem that Asian lady meets, covering up might as well be used deep color powder the principle that beat shadow is at the Sai, is the pattern that the both sides in trousers adds some deep colors side, it has a liking for the pants a little more narrow, match with the pattern fresh clear blouse to in order to transfer view, have a liking for to a leg department to lose much.

This method can make use of popular big flower pattern and add to spend trousers a side as well not Ai eye.

4.carry on the back fatty

Carry on the back a fatty person to certainly greatly hate backless dress, secondly be hated to wear vest, meeting give person tiger carry the felling of bear waist on tiger's back, in fact choose to wear deep color short sleeve blouse have already received certain effect,cheap women shoes style in brief is lord, disliking the monotonous words can leave detail at under body exertion, transfer the other people's attention, have a liking for go to will lose some.

The in fact deep color clothes make the person have a liking for to lose more, but will particularly put at under body, to pear form the shape Be the most suitable to match.

5.the leg is short

Want to make leg department a little bit higher, suggest to wear keeping of some narrow bodieses feet trousers, or and knee skirt, also need to add a rightness of sharp ends sandals or high-heeled shoes."

For oneself thin person speak, the narrow body keeps feet trousers certainly all right, but Asian's leg is usually fatty and short, this method will take care of a thing and miss the other, cheap fashion jewelryand the knee skirt go together with high-heeled shoes good, will have a liking for the legs go to very long.
