Analytic solutions of post-Newton metric component were got by series expansion in oblate ellipsoid coordinate system. 对由后牛顿效应产生的度规分量利用椭球坐标系及级数展开求得解析解。
After analysing the thermal expansion ellipsoid, we find out that the optimal seed orientation is [ 101]. 通过分析热膨胀椭球,[101]方向被确定为最佳籽晶方向。
Using the Stokes coefficients in gravitational field expansion of the Moon, we determined the lunar dynamical figure ( selenoid), then calculated the parameters of triaxial best-fitting ellipsoid of the Moon. 利用月球重力场展开式中的Stokes系数,确定了月球的力学形状(月球水准面方程),然后计算了最佳拟合的月球椭球体的参数。
