摘　　要：本文旨在指出相关文献中关于质点轨迹结果中的错误,并利用不同于相关文献的惯性参照系,给出修正和改进后的结果.The aim of this paper is to point out the mistake for the particle orbit in the conclusion of the relevant literature. The mistake has been corrected, and the result has been perfected by means of establishing the inertial reference frame which is different from the one used in the relevant literature.

关 键 词：质点 质心 椭圆摆 惯性系 轨迹
