查询词典 light-year

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。

The small hole of the optical inducer of the traditional second-generation optical mouse used for receiving the images faces downwards, and corresponding light sources (including photoelectric diode and laser diode), optic lens and photosensitive holes are arranged at the lower part of the mouse; therefore, moving the whole mouse is a relatively convenient method for generating displacement of the mouse pointer; oppositely, the small hole of the optical inducer used for receiving the images faces upwards and corresponding light sources, optical lens and photosensitive holes (7) are arranged at the upper part of the mouse; matters on the upper surface of the photosensitive hole (7) can be moved so as to lead the mouse pointer to generate the displacement, while the moving signal transmitted by a photoelectric conversion device must be reset so as to comply with the integrated mouse of the invention.

传统的第二代光电鼠标的光学感应器接收图象的小孔是向下的，对应的光源(包括光电二极管，激光二极管)、光学透镜和感光孔都是在鼠标下部分，这样要想鼠标指针产生位移较方便的方法就是移动整个鼠标；相反，光学感应器接受图象的小孔向上，对应的光源、光学透镜和感光孔(7)在鼠标上部分，要使鼠标指针产生位移就只需移动附在感光孔(7)上面的物质，但必须重新设置光电转换装置传出的移动信号，以符合本发明。

Experiments of photosensitization exhibited that, when irradiated with red light, the photodamaging effects on cells of both photosensitizers are close to each other; but when exposed to room light the cytotoxic effect of AISPC is lower than that of HPD, suggesting a potential advantage of reducing undesired side effects in clinical application.

光敏杀伤的结果表明，在红光照射下，两光敏剂对细胞有相近的杀伤效率；在室内自然光下，AISPC对细胞的损伤明显低于HPD，显示出其较低的光毒付作用，具有适合临床应用的优点。

In the region of light intensity between 1—400 lx,phototaxis of the beetle increased with light intensity.

在光照为1～400 lx范围内，趋光性随光照强度提高而增强。
