极化方向

• By driving expressions and using the method in numerical integration , the results of numerical calculations are analyzed , discussed and contrasted with different conditions , and they showed that there are evident differences in the mean attenuation , scattering , and back scattering cross sections of oblate spheroid particles when the variance is so small that it is near to zero namely it is the same as the rotatory axes are parallel with one direction and when h - polarized and v - polarized incident waves happened . these differences are depended on the relative differences in the average orientation of rotatory axes and the polarized directions of incident wave
  通过公式推导和数值积分计算并对结果做了讨论和分析，对比各种情况表明：扁椭球粒子群在方差很小接近为0时，与粒子群旋转轴一致取向的情况相同，入射波水平极化和垂直极化时的平均衰减截面、平均散射截面、平均后向散射截面有明显的不同，这决定于旋转轴平均取向和入射波极化方向的相对差异。
