n.遮蔽；跟随；加阴影
动词shadow的现在分词形式.
This paper analyzes the influence of the shadowing effect for different surface RMS slope. 本文分析了不同表面均方根率对遮蔽效应的影响。
In addition, a shadowing function applicable to multiple scattering is taken into account, which extends the calculation to the surface with anisotropic slope distribution. 引入考虑多次散射的遮蔽函数来修正掠入射情况下的散射系数，并将计算范围扩展到均方根料率各向异性的二维粗糙面。
