oblate spheroid meaning in Chinese
扁球体
扁球形体
扁椭面
Examples
- He shows that the earth is not a true sphere but an oblate spheroid and calc ulates the flattering .
他证明地球不是一个真的球而是一个扁球，而且计算了扁平度。 - 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
结果表明，在其它试验条件不变的条件下，适当降低发射药堆积密度、适当提高发射药中硝化棉( nc )含氮量、选用恒面燃烧的扁型药、降低发射药粒度均有利于提高射钉的穿透能力。 - 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。
