摘　　要：该文从三阶Lagrange方程和耗散力的形式出发,给出了力学系统在耗散力的作用下三阶Lagrange方程的形式,并给出了一个具体的实例来证明得到的理论的正确性.Based on the three-order Lagrangian equations and dissipative force,the form of the three-order Lagrangian equations under the action of dissipative force has been studied.The example shows that to the problem of motion containing dissipative force,it is easy to obtain the solution by solving the three-order Lagrangian equations.
