摘　　要：将改进的虚拟压缩恢复法应用于扰动引力的逼近问题,与点质量法的比较表明,改进的虚拟压缩恢复法和点质量模型对扰动引力的逼近精度和逼近速度相当。To approximate the disturbing gravity, the fictitious compress recovery approach is used and compared with the approach of point mass. The results show that the accuracies and the computation speed of these two approaches are equivalent to each other.
