The second experiment is to fabricate white light LED from red and green phosphors pumped by blue light LED. The blue light LED we used in our experiment has the wavelength range between 450 and 452.5 nm, and the chip size is 17 mil *14 mil. There are two kinds white light LED we fabricated in the experiment. There are three blue light LED chips bonded in single package of both kinds package. The different of the both packages is mixed phosphor of encapsulation. One of the experimental devices was encapsulated YAG phosphor mixed silicone to fabricate white light. The other is red and green phosphor mixed encapsulation. The compared and focused parameter was luminous efficiency. YAG phosphor pumped white light has the luminous efficiency 72 lm/W, CRI 70, CIE(0.32, 0.33), CCT 5622°K at the operating current 60mA. On another hand, red and green phosphor pumped white light LED has the luminous efficiency 55 lm/W, CRI 90, CIE(0.31, 0.32), CCT 6479°K at the operating current 60mA. We fabricated the red and green phosphor pumped white light LED, and proved that it could has much higher CRI under similar compared conditions, CIE xy and CCT.

第二个实验是使用蓝光LED晶粒来制作白光元件，蓝光LED晶粒波段范围在450 ~ 452.5 nm，晶粒大小为17*14 mil，以三颗蓝光LED晶粒搭配YAG萤光粉(黄绿光 540 nm)制成白光元件，再以另外三颗蓝光LED晶粒搭配红色萤光粉(613 nm)混合绿色萤光粉(519 nm)制成的白光元件进行发光效率比较；搭配YAG萤光粉的白光元件在注入60 mA的电流时所量测到最大的发光效率是在72 lm/W，演色性数值大约为70，CIE色度座标为(0.32， 0.33)，色温是在5622 °K；而搭配红色萤光粉混合绿色萤光粉的白光元件在注入60 mA的电流时，最大的发光效率在55 lm/W，演色性数值大约为90，CIE色度座标为(0.31， 0.32)，色温在6479 °K；证明了蓝光LED晶粒搭配红色萤光粉混合绿色萤光的白光元件演色性指数可以高达90 以上的结果。

Second, in this paper we recite and analyse how the painting masters of the different history stage used light and colors from "Prehistorical art" to "Rome art" imitating light and colors,"Middle ages art" creating "Sanctitude light","Revival of learning" representing nature light and colors and then light was used to create the drama light, Impressionistic using the light of science and impairing light instead emphasizing sensibility colors in modern times. Painting lives by the light and colors all along in the painting history.

从史前艺术、希腊罗马艺术的模仿光与色，到中世纪艺术创造神圣之光，再到文艺复兴的再现自然光线与色彩，然后到17世纪的主观处理光线形成"戏剧之光"、印象派的科学用光、现代绘画淡化光线并强调情感色彩，光线和色彩一直贯穿在历史的绘画长河里。

From an extensive molecular epidemiological surveillance around the H5N1 infected regions in the past several years, H5N1 viruses were isolated from the wild birds, eg.

Likewise, there were three main forms of government, each supported by a social "principle": monarchies (free governments headed by a hereditary figure, e.g. king, queen, emperor), which rely on the principle of honor; republics (free governments headed by popularly elected leaders), which rely on the principle of virtue; and despotisms (enslaved governments headed by dictators), which rely on fear.

同样的，存在三种主要的政府形式，每一种由一种社会&原则&支撑：君主制（以一个继承的人物，比如国王，王后或皇帝为首的自由政府）依赖于荣誉原则；共和制（以大众选举的领导者为首的自由政府），依赖于美德的原则；独裁制（以独裁者为首的奴役政府），依赖于恐惧。
