从实验和理论上研究了滚摆的运动,得到了滚摆滚动最大高度和滚动时间随滚动次数的变化关系。揭示了空气阻力及摆线间摩擦力等因素对滚摆运动的影响及其引起的系统机械能损失。
從實驗和理論上研究瞭滾襬的運動,得到瞭滾襬滾動最大高度和滾動時間隨滾動次數的變化關繫。揭示瞭空氣阻力及襬線間摩抆力等因素對滾襬運動的影響及其引起的繫統機械能損失。

The motion of rolling pendulum was studied experimentally and theoretically . The functional relations w hich describe the dependence of the maximum height and rolling time of the pen-dulum on the rolling number were obtained .The influence of air resistance ,friction between the rope , etc .on the motion was discussed ,and the total mechanical energy loss caused by these factors was ob-tained .
