扁椭球 meaning in Chinese
ellipsoid，oblate
oblate ellipsoid
Examples
- In reality the earth is not exactly spherical but rather shaped somewhat like a flattened ellipsoid .
实际上地球不是精确的球形，而有点象一扁椭球。 - Abstract : taking advantage of charge simulation method and potential coefficientmethod for ellipsoids , point effects of electric field near the surfaceof a satellite are calculated nummerically . antenna point effects on a high voltage spherical satellite arecalculated as an example
文摘:本文使用模拟电荷法和扁椭球体的电势系数法较好地解决了尖端效应的数值计算问题,并用这一方法,计算了卫星表面尖端的效应 - Besides , successfully calculating the electromagnetic four - potential in the spacetime of charged black hole expressed by the generali zed spherical coordinate and furtherly solving the h - j equation of such spacetime make it possible to get the exact description of the energy extent of nonthermal radiation particle and to study the characteristics of such black hole ' s nonthermal radiation
另外，本文还求出了一类用扁椭球坐标表示的荷电黑洞时空中的电磁四维势矢量，从而成功地求解了此类弯曲时空中的hh方程，得到了这种非热辐射粒子能量范围的精确表达式，从而对这类黑洞的非热辐射特征进行了研究。 - 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。
