stoichiometric proportion meaning in English

化学计量比

The results indicate that ( a ) before heat treatment , with the increasing of substrate temperatures , content of lower valency ( tij + ) decreases , the stoichiometric proportion of o / ti in all samples is about 2 ; the films have amorphous incompact columnar fiber structure , and with the increasing of substrate temperature , the size of columnar fiber increases ; the films have good hyalescence in visible range and great absorbability at the wavelength of 350nm ; optical constants of the films are calculated from the transmittance spectrums in visible range by mathematical analysis of the orders of interference , the results show that the refractive ind
研究结果表明， ( a )热处理前，随着基片温度的增加，薄膜中的低价氧化钛含量逐渐减少，化学计量比趋于o ti = 2 ；薄膜具有非晶态不致密的柱状纤维结构，柱状纤维的尺寸随基片温度的升高而增加;薄膜在可见光范围内透明，在波长为35onzn时严重吸收，利用干涉级次法分析了薄膜的光学常数，结果表明，薄膜的折射率随基片温度的升高而增加，根据计算结果得到了tioz薄膜在不同基片温度下的折射率色散曲线。
