以平面圆形限制性三体问题为基本研究模型，对比研究速度近似改正方法和速度坐标近似改正方法关于最大李雅普诺夫指数和快速李雅普诺夫指数的计算时间问题。结果表明：加入改正项后，速度近似改正方法的时间效率要明显优于速度坐标均近似改正方法。该研究对太阳系多体问题具有重要的应用价值。

The paper discusses the time efficiency problem on the Maximum Lyapunov indicator and the fast Lyapunov indicator for two kinds of approximate manifold schemes ,namely,velocity method and ve-locity and position method .The Planar circular restricting three-body problem is adopted as the basic model.The results show that the velocity approximate method has more priority than the velocity and posi -tion method .The research has great application value in multi-body problems in Solar system .
