解釋
扁球體-
He shows that the earth is not a true sphere but an oblate spheroid and calc ulates the flattering.
他證明地球不是一個真的球而是一個扁球，而且計算了扁平度。 -
The results show that the penetrability of powder loads can be improved when suitably reducing bulk density and grain size of gun propellant, increasing nitrogen content of nc and choosing oblate spheroid explosive respectively under the constant test conditions
結果表明，在其它試驗條件不變的條件下，適當降低發射藥堆積密度、適當提高發射藥中硝化棉（ nc ）含氮量、選用恆面燃燒的扁型藥、降低發射藥粒度均有利於提高射釘的穿透能力。 -
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並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、平均後向散射截面有明顯的不同，這決定於旋轉軸平均取向和入射波極化方向的相對差異。
