radiant transmittance

In this paper we define the reflectance and the transmittance, and then by calculation we further identify that radiant energy obeys law of conservation of energy as the light passes increased transmission layer.

本文定义反射比和透射比后，通过具体计算，证明光通过增透膜时，辐射仍能满足能量守恒定律。

Secondly, other parameters such as temperature difference and emissivity of target and sky, molecular absorptive transmittance, instantaneous field of view ( IFOV), contrast threshold and radiant wavelength are discussed in detail.

然后，对目标天空背景温差、发射率，气溶胶衰减系数，瞬时视场、对比度探测阈值以及辐射波长等参数作了详细讨论。

Spectrum properties of light conversion agricultural films about transmittance, radiant intensity quantum current density were determined and analyzed, and spectra distribution of sunlight and transmissible light through the film were given.

测试分析了转光农膜的透光值、辐射强度、量子流密度等光谱特性，并给出了北京地区自然光和转光膜透过光的光谱分布。
