摘要
利用算子运算的方法,对求定外空扰动引力的Bjerhammar方法、虚拟点质量方法以及虚拟单层密度方法进行了系统地归纳;利用Possion核的再生特性及球谐函数的正交性质,给出了它们之间的换算关系;最后从两个方面分析了实用计算中各种方法的优劣。
This paper sums up disturbance gravitational computation methods(Bjerhammar, suppositional point mass, suppositional single layer density) by using operator operational method. These methods' conversion relations are given in accoordance with Possion's regenerated characteristic and spherical harmonic property. Finally, the paper analyses merits and demerits of three kinds of methods in two respects.
