surface scattering layer的意思|示意

For the light to be trapped in two dimensions, the object's surface needed to be smooth enough to cleanly reflect most of the light into the oil layer rather than scattering it at all angles.

要把光被捕获在两维的曲线状表面上时，要求物体表面非常平滑，才足以把大部分光线干净利落地反射进油层而不是分散在所有的各个角度上。

It may be used to remove some negative influences of scattering, multiple wave and inhomogeneity in surface layer when people don't know the detailed data of surf...

该算法可以在不知道地表层的详细资料的情况下，消除地表层散射、多次波和非均匀性等的影响。
