准坐标系下的三阶Lagrange方程的一种推导

Deduction on Third Order Lagrange Equation in the Pseudo-Coordinates

该文从完整系统的三阶Lagrange方程出发,推导了完整系统在准坐标下的三阶Lagrange方程.由于准坐标比广义坐标更具有普遍性,所以准坐标系下的三阶Lagrange方程比广义坐标下的三阶Lagrange方程更具有普遍性.

This paper gets third order Lagrange equation in the pseudo-coordinates system based on the third order Lagrange equation in the general coordinates of the integrated system. Because of the generality of pseudo-coordinates, the third order Lagrange equation in the pseudo-coordinates is more general than the third order Lagrange equation in the general coordinates.
