摘　　要：针对理论力学中的研究对象、基本方程和基本物理量的对比分析,阐明了牛顿力学与分析力学两种方法的特点及联系,通过两种方法在研究力学体系的平衡问题和运动问题的比较,表明分析力学方法具有更高的概括性和统一性,它使得经典力学的理论体系更加严谨。For comparative analysis of reseach objecs, Basic equation and Basic physical quantities in Theoretical Mechanics, this paper discusses the characteristics and relationship between the Newton＇s Mechanics and Analytical Mechanics. To compare two methed in the questions of balance and kinematics in the mechanics system, the results show that the method of Analytical Mechanics is more comprehensive and general, which make the classical mechanical system more complete.
