这些样品表面具有连续平滑的起伏轮廓，符合粗糙表面散射研究的理论模型，也可用作相位板。
These surfaces have a smoothly modulated profile which is amenable to the theoretical model of rough surface scattering. These specimens can also be used as phase screens.
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.
利用基尔霍夫近似研究了表面均方根斜率较大的二维粗糙面的多次散射问题。
Multiple scattering from two-dimensional rough surface with large surface root mean square(RMS) slope is studied with Kirchhoff approximation.
