Multiple scattering from two - dimensional rough surface with large surface root mean square ( rms ) slope is studied with kirchhoff approximation 摘要利用基尔霍夫近似研究了表面均方根料率较大的二维粗糙面的多次散射问题。
The root mean square roughness ( rms ) of sto thin film was 0 . 77nm in the range of 10 m . the step - flow growth mode of sto thin film was achieved 实现了sto薄膜的准二维层状模式生长,在10 m范围内, sto薄膜的表面粗糙度rms为0 . 77nm 。
