查询词典 light-pipe

If the display of such lights by the time easy to speed up the longer the aging CRT phosphor, lower luminous efficiency (in the strong light environment, in the face of the display work, our eyes will be extremely vulnerable to damage the screen light reflection).

如果显示器受强光照射，时间长了容易加速显像管荧光粉的老化，降低发光效率（在强光照射环境下，面对显示器工作的人员，眼睛也极易受到屏幕反射光线伤害）。

The project ducts research on new sealing structure of power-type white light emitting diode to achieve low thermal resistance and emitting efficiency over 80lm/W. It can promote phosphor transfer efficiency and improve sealing technique procedure, introduce automatic production and testing equipment,to increase white light LED emitting efficiency and other performance indexes and further large-scale productivity.

A structure of C/ TiO2/ITO and ITO/TiO2/ITO were used to test the photoconductivity of TiO2 thin film using a black light lamp as light source.

以黑光灯为光源，采用ITO/TiO_2/ITO和C/TiO_2/ITO结构通过光电流测量了锐钛矿相TiO_2薄膜的紫外光响应。

Since ultraviolet light is only 3-5% part of the solar spectrum, the photocatalytic activity of TiO_2 can not be sufficiently activated under solar light irradiation, which strongly limits the use of solar spectra as a source for photodecomposition of pollutant.

纳米TiO_2由于具有较高的光催化活性，化学性能稳定，无毒等优点，成为了最受人们关注的光催化材料之一。

The apparatus includes a photodetector optically coupled to the light source and designed to receive the light signal.

该装置包括一光检测器，所述光检测器与光源光学连接，并设计为接收光信号。

Through the invention, an infrared light is up-converted into a visible light which can be easily absorbed by a dye-sensitized nano material, and can help dye molecules to absorb sunlight of wider spectrum, thereby further improving the photoelectric conversion efficiency of the cell.

本发明它可将红外光上转换为染料敏化纳米材料易于吸收的可见光，可以有利于增强染料分子吸收更宽谱域的太阳光，这样将进一步提高电池的光电转换效率。

The intensity of a source of light, such as an electric light bulb, can be measured with a photometer.

光源的强度，比如电灯，能用光度计来测量。

The usage divides the light photometer, measuresing the aqua to absorb the intensity of light in the wave-length 520 nm.

我的第一份工作我不想在我21岁的辉煌时期中受到被炒鱿鱼的打击中就此遗憾一生！

Compared with the effects of light density and light colour on the growth of Chinese shrimp in shrimp intensive culture, the choice of the photoperiod was minor.

与光照强度光谱组成对中国对虾生长的影响的研究结果相比，在中国对虾的集约化养殖生产中，光照周期的选择是次要的。

The results showed that there were very good heat preservation and light-taking performance in the solar greenhouse, but in the cold season, temperature and light conditions in the solar greenhouse could not meet the needs of thermophilic, photophilous fruits, vegetables and crops, etc.

对阿拉尔市普遍用于冬季蔬菜种植的日光温室内温度和光照测定结果表明：日光温室虽有很好的保温采光性能，但寒冷季节，日光温室内的温光条件仍满足不了喜温、喜光等果菜类作物正常生长的需要。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
