【摘要】 可倒摆实验是各高校精确测量重力加速度的实验.综合文献,可以看出,各高校的可倒摆在结构上,稍有不同,就是在摆杆上加了一个、两个、三个或者四个摆锤.但是无论摆锤有几个,可倒摆实验所应用的原理是一样的,就是在实验中依靠移动摆锤,来移动可倒摆的质心位置,从而确定可倒摆的共轭点.对可倒摆的质心坐标与等值摆长的关系做了详细的讨论,并将所得的结论与前人[2]的工作做了对比,可以看出本论文结论与文献的结论是互相吻合,互相验证.更多还原

【Abstract】 The accurate experiment for the acceleration of gravityg is pendulum being used for colleges and universities. The pendulums structure is different because of the pendulums can holding one,tw o or three even four shifting pendulums. But the pendulums applied principle is same synthesizing the literature. The determining for conjugate point depended on shifting pendulum thus changing centroid coordinates. We obtained the conclusion coinciding w ith previous w ork.更多还原
