基于等时性和利用微分几何中的Cesdro方法,解析地确定等时摆球的运动轨迹以及限制摆绳运动的曲线,同时还获得摆绳上不同等分点运动曲线的一般解析式.所得结果将有助于全面认识此等时摆系统的运动学规律。
Using Cesaro's method in differential geometry, the trajectory of an isochronous pendulum ball and the shape of the limiter are determined analytically. General analytical expressions of the trajectories of the swinging rope at equal division points are further derived.
