太阳散射辐射 meaning in English

diffuse solar radiation

Attempt to calculate the diffuse irradiation on the actual terra by used of the modern geo - information technology and the high resolution digital elevation model , we focused on 3 points in discussion : 1 . to construct an appropriate model to describe the anisotropic character of the diffuse - radiation . according to the circle - sun suppose , we decomposed it into 2 parts , one is the isotopic part and the other is anisotropic
本文的讨论主要着眼于三个方面： 1 、散射辐射各向异性特点利用环日假设理论，把太阳散射辐射分解为各向同性散射和环日散射两部分，并以水平地面上的直接辐射和散射辐射各自在总辐射中所占比例来表示其权重，描述实际散射辐射各向异性的特征。
