摘要
本文给出准速度和准加速度联合表示的一阶和二阶非完整系统相对运动的Appell方程。并将所得结果推广到变质量系统,最后举例说明新方程的应用。
In this paper the new forms of Appells relative motion equations of the 1st order and 2ndorder nonholonomic systems in terms of quasi-velocities and quasi-accelerations were given.The results ohtained were extended to variable mass systems. And an example was given to il-lustrate the application of the new equations.
