light transmission rate
Examples
- Test and analysis some properties such as crystal structure , superficial resistivity , light transparence , absorption coefficient etc . obtain the best technical process and parameters with analyzing how film thickness , deposition rate , boat temperature , substrate temperature affect the films " structure and optical and electrical properties
并对薄膜的晶相结构、电阻率、光透过率、光吸收系数等电学和光学性质进行了测试和分析。通过分析薄膜厚度、沉积速率、舟温、基温等工艺参数对薄膜结构及光电特性的影响，得出了制备复合光吸收层的最佳工艺参数以及工艺条件。 - Sio2 optical anti - reflective thin films with micropores were prepared with esam method . the optical properties of pdda / sio2 complex films against the changes in temperature in the processof heat treatment were studied . after heat treated at 520 c , the light transmittance at certain wavelengths of the thin improved greatly . the chemical bond structures of the optical thin films was studied with ft - ir , and surface analysis of the thin films was carried out using xps and their anti - scratching performances were studied
用esam法制备了sio _ 2多孔光学增透薄膜，研究了pdda sio _ 2纳米复合薄膜在热处理过程中光学性能随温度的变化规律，发现520热处理后一定波长下的光透过率大大增强；用ft - ir研究了热处理后的薄膜的组成，用xps进行了表面分析，研究了薄膜的耐机械擦伤强度，发现1 ~ #薄膜的耐机械擦伤强度较小，甚至小于相应的pdda sio _ 2纳米复合薄膜的耐机械擦伤强度，而2 ~ #薄膜的耐机械擦伤强度则大大增强，即使用刀片平刮也只略有损伤。 - The experiments show that the color of the iceland spar can be changed when heated to a certain temperature , that is , light yellow iceland spars will fade when heated to 360 - 370 , while dark yellow iceland spar will fade at 440 - 450 , brownish yellow iceland spar at 460 - 470 ; and the color of light purple iceland spar can be removed when heated to 390 - 400 , while the color of deep purple iceland spar can be removed at 440 - 450 , deep reddish purple iceland spar at 460 - 470 . on base of the u - v absorption spectrum , we find that the u - v absorption spectra of the faded iceland spars are paralleled to the x axis , the transmittance of them are also greatly improved
实验表明，冰洲石在加热到一定温度时颜色会发生变化：浅黄色、深黄色和褐黄色冰洲石分别在360 - 370 、 440 - 450和460 - 470完全褪色；浅紫色、深紫色和深紫红色冰洲石分别在370 - 380 、 440 - 450和460 - 470时完全褪色。通过对褪色后冰洲石进行紫外-可见光吸收光谱测试表明：完全褪色后的冰洲石在紫外-可见光的吸收光谱上表现为一条近平行x轴的直线；紫外、可见光区的紫区的光透过率有了很大了提高。
