Energy saving lamp is also called compact fluorescent lamp। In addition to white (cold) light, there is still yellow (warm) light. In general, in the same watt situation, an energy saving lamp can save 80 percent energy of incandescent lamp and only 20 percent thermal radiation. In normal condition, a 5 watts energy saving lamp is equivalent to 25 watts incandescent lamp and 7 watts is equivalent to 40 watts.
It is first invented by foreign manufacturers in 1978। Because of high efficiency (5 times than ordinary light bulb), significant energy saving, long life (8 times than ordinary light bulb), small size and easy to apply, it is popular with people and countries। Now, many families have already used the lamp। So, how do consumers distinguish the quality of it? Following below:
1. Select the products with safety certificate, whose quality can be guaranteed.
2. The packing should be fine and beautifully printed. Name, address, telephone number, complete instructions and other information are complete. Check the appearance of light and its plastic part should be marked clearly the source (it may be a trademark or name of manufacturer), rated voltage and voltage range, rated power and rated frequency;bulbs should be smooth, no bubbles;phosphor coating inside the lamp should be fine, no granule and uniformly white;lamps and plastic parts should be securely connected, not loose;no sound when hand shaking the whole lamp.
3. The plastic case must be made from specific engineering plastic and ordinary plastic is banned for production. In addition, compare lights and choose with good consistency in shape and size. Meanwhile, The shell can not be cracked and loose.
4.Booster available is the best when purchase. Regulate the booster to 150V (or the minimum voltage marked on the instruction) and equip with an energy saving lamp,then it should be able to pass once when power is on. Because energy saving lamp starts with two characteristics:First, the higher the temperature is, the easier to start;Second, it is easily started under the effect of human body. It is worth mentioning that there should be about 0.4 second start delayed time after setting up the filament preheating circuit inside a lamp.
5. Electromagnetic compatibility is the necessary performance of household appliances. When you buy, examine whether it is through the test.
6. The temperature of energy saving light rises slowly in normal state, otherwise, its life will be short. Meanwhile, both ends are black or filament is red or flashing when the lamp is on shows it has quality problems.
7. Purchasing the energy saving lamp, you can only consider the price, regardless of quality. If blind pursuing low price, it is very likely to buy substandard products.

What if The World Without Google?
Google,no doubt one of the world's best known companies.It not only allows people to freely access information and give reasons for the existence of e-commerce,the most important thing is that it proves to the world:free of charge can earn!Perhaps all these make you more like to know - what if the world without Google?
There may be a number of assumptions:Perhaps Microsoft will even worse off than today? Maybe Apple will bankrupt? yahoo is no longer be the world's most powerful company? What the world will be without google?
Yahoo:
You can not forget it - as Google's biggest rivals,yahoo has now been thrown far behind.It has all:adequate capital,a broad user base,a strong business.It really needs is a leader in insight to lead it to success.
If without Google,Yahoo,entirely possibly has a huge space for development in the Internet field,and eventually become the most influential Internet companies - not Microsoft or Google.But,in fact, because Jerry Yang(Yahoo's founder)'sindecisive, Yahoo prosperity will not be renewed once already.Even in the fierce competition,Yahoo has not taken measures to improve itself.
This gives us reasons to believe:even if there is not Google,the other competitors will beat Yahoo.Perhaps this is the fate of Yahoo.
Microsoft:
If Google is the end of the tunnel of light,Microsoft is among the darkness of the tunnel - the ubiquitous,but difficult to detect.If not Google,open source software will not come,Windows operating system are still powerful than ever before,desktop software will be always important.In addition,Microsoft will be fiercely compete with Yahoo on the online advertising and cloud computing.
However,Google has brought the concept of cloud computing and develop a rich services based on cloud computing.If any services can be achieved in the clouds, desktop applications will be replaced by clouds,which will direct threat to the Window operating system dominance.Microsoft also had to face Google,seen from the launch of the online version of Word and Windows Azure.
But we can clearly see that: Google has been to avoid direct invasion of Microsoft's core territory.Over the years,until recently with the development of Chrome OS and Google Android was launched to challenge Microsoft.
Perhaps you might want other competitors to challenge Microsoft.However,who will be such capital in addition to Google?
Apple:
Speaking of the Internet,maybe you must mention Apple.Because Apple has become strong enough.In the field of mobile phone operating system,Google and Apple's competition is perhaps the most eye-catching.People are always very keen to compare Android and iOS.But we think:If there is no Google Maps,YouTube and the Web-based universal application,application of iPhone will be freezing. Perhaps iPhone will lose the important competition bargaining chip with BlackBerry and Windows Mobile.
In all,what google gives us is far beyond the above.If without Google,our lifestyle will change.So we thank Google for the free information,and rich applications.It also embody the leadership of Google for Internet.

EVA
Ethylene Vinyl Acetate (also known as EVA) is the ofethylene vinyl acetate copolymer. The weight percent of vinyl acetate usually varies from 10-40% with the rest of ethylene.
It is a polymer that approaches elastomeric materials in softness and flexibility, however, can be processed like other thermoplastics. The material has good clarity and gloss, barrier properties, resistance to low temperatures, stress-crack resistance, hot-melt water-proof properties, and resistance to UV radiation. EVA has little or no odor and is competitive with rubber and vinyl products in many electrical applications.

Ten Highlights Of Apple iPhone 4G
1, the new appearance design
If you say iPhone 3GS 's greatest shortage in the eyes of players, many people would take static appearance as an option, and compared to the second generation of iPhone 3G, 3GS has little change in appearance, for now mercurial users, it is indeed a small regret. But as one of superior manufacturers of industrial design, Apple did not intend to use one way, from the previously leaked iPhone 4G photos, we easily see that the new generation of iPhone 4G change in appearance can be said to radical.
Smaller size, more weight
In the mobile phone model on the whole idea, iPhone 4G continued large touch screen mobile phone tradition, the use of the IPS hardware screen screen positive for the cell phone screen and only one entity key. The size and shape on the size, iPhone 4G iPhone products relative to the change before the obvious, first of all in the back of the phone, iPhone 4G abandoned the previous generations of products, curved design, graphic design to be more tough; second iPhone 4G The body length and width down about 2mm, and in the body thickness is reduced from the iPhone 3GS of 12.3mm for the 8.2mm, the thinnest mobile phones among the ranks of success; Finally, body size is declining, iPhone 4G The overall weight has increased to 138 g, compared with 3GS increased by 3 grams, which can also see a solid material iPhone 4G.
2, front camera
Although second-generation iPhone turned Apple has provided that for 3G network support, but is the iPhone 3G, whether or 3GS, We have not seen pre-camera presence, to make video calls to users Dasuan, no doubt, is a great tragedy. In order to completely change the iPhone this dilemma, a new generation of Apple's iPhone 4G in to add a front camera settings. Although we have not learned this Apple iPhone 4G detailed specifications of the camera front, but it is certain that in the flagship and market mobile phones compared, iPhone 4G a front camera and not only better behind, after all, for Apple, this is the iPhone 4G iPhone with previous generations of products, one of the main differences between a.
3,3.7-inch screen
I remember in 2007, large-screen cell phone market is still relatively rare, 2.4-inch screen should be the main specifications of that era. Apple's first generation of iPhone craze, blockbuster, directly to the screen size increased to 3.5-inch level, IPS hardware screen screen also made breakthrough progress in quality, today, 3.5-inch screen in the mobile phone market where can still be called a mainstream design touch is the mobile phone industry in
4,960 × 640 resolution
For mobile phones, the screen size is certainly a major target, but players pay more attention to the resolution of the screen or parameters to compare the same size screen, higher resolution display will be better quality and finesse. Now you can see a lot of use of large screen mobile phones, due to insufficient resolution, resulting in display is difficult to accept the situation, so many players have such an idea, that is, choosing to large-size low-resolution, as medium-size design with high resolution.
5, Apple A4 processor
As a smart phone, iPhone has always been the type of processor performance that in the first and second generation iPhone, Apple chose Samsung S3C6400X processor, this processor speeds up to 533MHz at the time Apple iPhone can be said to ensure the supremacy of the strong backing; in the third generation of the iPhone 3GS, Apple will upgrade to the ARM processor's Coretex A8 processor, the dominant frequency is slightly raised to 660MHz, so the phone's performance has enhanced.
6,512 MB memory
Memory has always been a smart phone running the basis of fluency, not clear that the subject of many smart phones running the memory capacity is too small and there is not smooth trouble, but Apple's iPhone has been optimized in this area are quite strong, Although the first generation iPhone just to run with 128MB of RAM, but fluency is still commendable, and in the second generation of three generations of iPhone, run the memory to a 256MB, so fluency have followed better.
7,500 megapixel main camera
For iPhone, the camera has always been its main selling points are not, so you can see the first generation, second generation iPhone is using only a 200-megapixel camera, while the iPhone 3GS although was slightly improved, but still remain in the 3 million pixel level, for many gamers, this camera is clearly not into their discernment, and seeing other brands of mobile phone cameras have advance toward the 10 million pixel level has been steady for Apple now also sit still the.
8, LED fill light
While the mobile phones, the film features an ancillary equipment only, but in comparison, and professional camera phone photography or the more obvious advantages, after all, every day, each one can stroll around with a camera, imagine if one day they want to hit Le shoot the scene, while the hand is not the camera, then the phone will become your only choice.
Products before the iPhone, although the camera's specifications acceptable, but all do not have the fill light, so light, under conditions of good quality film can be acceptable, but poor light conditions or the performance of the night on the unacceptable. IPhone products in order to improve low-light shooting conditions, the performance of Apple's iPhone 4G on the latest addition to the camera up to 5 million pixel size but also increased the LED light up design, quality improvement for the film played a certain role.
9, iPhone OS 4.0
Among the many smart phone operating system, iPhone OS can be said to compare different type of a product, it should be said that Apple's operating system by pouring in the hard work is obvious to all, regardless of the hardware or the actual performance of the optimal operation of fluency, iPhone OS are called first-class, or first-generation iPhone will not have formed such a large mobile phone market impact, today, iPhone OS is still the leader in smart phone operating system.
10, Micro-SIM card
The users should be familiar with iPad know, 3G version of the iPad was not used on the traditional ordinary SIM card, but more compact Micro-SIM card, so a lot of domestic players in the 3G version of iPad buy, the largest trouble is how to cut domestic SIM ordinary size available Micro-SIM card, and even spawned a cut card of such a service. If users are interested in the new generation of the iPhone 4G, then this will also face encumber.
In the IT industry, Apple has always been a leader in the trend, only the iPad, and used on the iPhone 4G Micro-SIM card, for example, in the absence of any one operator position will be introduced this type of SIM card, so apples can be again this served as wagering such a role, in iPhone 4G dawn, if the players would like first to experience this new generation of products, then iPhone, cut card will have to experience of a test.
