这种粗糙表面可导致对光的散射，改变原有影像对光的吸收和反射的特性，从视觉上让人感觉到黑白照片影像变得模糊、淡化。
This coarse surface causes light scattering and changes original properties of the light absorption and reflection, which makes original image become fading and mildewing.
随后，本文着重分析了空-地随机大气信道的吸收、散射和湍流特性。
Subsequently, we stress on the absorption and scattering characteristics of space-to-ground atmospheric stochastic channel.
