摘要
用把方程的解设为余弦函数多项式的一种直接方法，求解了受幂律引力作用的质点一类非线性轨道微分方程。
Using a direct method regarding solution of a equation as a polynomial of cosine, a kind of nonlinear orbital differential equation of a particle exerted by attractive central force following power law is solved. It is pointed out that the orbit of a particle ejected from apsis is a sine spiral.
