total transmittance

Methods: Drug packaging materials were analyzed by ATR ( Attenuated Total Reflectance ) infrared spectrophotometry and transmittance infrared spectrophotometry.

方法:分 别采用衰减全反射(ATR ) 红外光谱法、透射光谱薄膜法等对药品包装材料材质进行定性分析.

In this paper, the solar heat gain ( SHG) formula for the triple glazing window of the room and the solar transmittance, absorptance of each pane, total absorptance and the total reflectance of the triple glazing have been given.

本文导出了通过三层玻璃窗进入室内的太阳辐射得热量公式以及三层玻璃的总透过系数、每层吸收系数、总吸收系数和总反射系数。

The power loss caused by the variation of the solar radiation transmittance and the solar cell ′ s temperature was calculated independently, and the total cell power loss computation model including the two factors was developed.
