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 通過公式推導和數值積分計算并對結果做了討論和分析,對比各種情況表明:扁橢球粒子群在方差很小接近為0時,與粒子群旋轉軸一致取向的情況相同,入射波水平極化和垂直極化時的平均衰減截面、平均散射截面、平均后向散射截面有明顯的不同,這決定于旋轉軸平均取向和入射波極化方向的相對差異。

It is also found by comparing with different mean cross sections that there is similar variability for the mean attenuation and scattering cross sections as a function of the different variance , expectation and the wave lengths , but there is much difference for the mean scattering and back scattering cross sections especially when the rotatory axes are oriented randomly in normal distribution in oxy plane or oyz plane and 3d space 還對比各種平均截面可知:對于平均衰減截面、平均散射截面兩者隨方差、期望及波長有著相似的變化規律;但平均散射截面、平均后向散射截面之間,有著很多的不相同,特別在旋轉軸在oxy平面、 oyz平面內和在空間oxyz內隨機正態取向時的情形。

With the increase of variance , the difference in h - polarized or v - polarized incident wave and in the different mean cross sections is becoming gradually small until when the variance is infinity namely the rotatory axes of the group are uniformly oriented : at this time the different mean cross sections are independent of the polarized status of incident wave 隨著方差的增大,入射波水平偏振和垂直偏振時的各平均截面的差異逐漸減小,減小到直至方差為無窮大時,即與粒子群取向的均勻分布的情況相同,此時各平均截面與入射波的偏振狀態無關。

Symmetries are existed in oxy and oyz planes for horizontally and vertically polarized waves , i . e . one ' s h - polarized case is the same as the other v - polarized one . while the expectations of the rotatory axes oriented in oxz plane are complement , one ' s h - polarized case is the same as the other v - polarized one 平面oxy和平面oyz對于兩種偏振極化入射波時存在著對稱性,一者的水平極化與另一者的垂直極化情況相同;而oxz平面內旋轉軸的平均取向的期望互余時,一者的水平極化與另一者的垂直極化時的情況相同。
