The life of white LED using silver glues is longer than using epoxy resins but initial luminous flux is much lower by1 / 3 .

使用银浆固晶比用环氧树脂寿命长，但初始 光通比环氧树脂低近1／3；

And by analyzing the composing of white LED and relations between current temperature and luminous flux refractive index is improved the interface between the sapphire underlay and epoxy resin by gelatinizing a layer silica gel .

通过对 白光LED的构成和电流/温度/ 光通 量的分析，可知在蓝宝石衬底和环氧树脂的界面间涂敷一层硅橡胶能改善光的折射率。

To promote white LED flux efficiency from three points based on LED resin phosphor and reflector cavity parameters optimization .

研究从封装树脂材料、荧光粉和聚光腔结构参数优化三方面提升 白光LED的 发光效率。

A white or colorless slightly acid solid that is soluble in water and ethanol ; used in the manufacture of glass and paper and adhesives and in detergents and as a flux in welding ; also used as an antiseptic and food preservative .

一种 白色或无色的 弱酸固体，能溶于水和酒精，用于制造玻璃、纸和粘合剂。

The results indicated : ( 1 ) The incidence of yellow and white flux of piglets in test group 1 and 2 was 14.3 and 26 . 8 percentage points lower than that in control group ;

结果表明：（1）试1组试猪黄 白痢发病率比试2组与对照组分别低14.3与26.8个百分点；
