牛顿──拉格郎日方程组

NEWTON LAGRANGE EQUATIONS

本文导出了一组以广义坐标表示的动力学方程组。这组方程称之为牛顿—拉格郎日方程，他们等价于拉格郎日方程，文中举例说明了牛顿—拉格郎日方程的应用。

In this paper a set of dynamical equutions expressed by general coordinates arederived. These equations are named Newton-Lagrange equations.Theyare equivalent toLagrange's equations.The applications of Newton-Lagrange equations are explained byseveral examples。
