【摘要】 以河池学院力学实验室为例,分别通过FB327型单摆实验仪、FB210C型复摆实验仪和FB210E型自由落体实验仪测定重力加速度,并对三种测定结果进行对比和分析,得出三种测定方法误差产生的原理及减小误差的方法。此举为实验操作者对比和选择测定方法提供依据,为实验教学者提供教学参考。更多还原

【Abstract】 Taking the mechanics laboratory of Hechi University as an example,the authors measure the acceleration of gravity by using FB327 simple pendulum,FB210 C compound pendulum and FB210 E free falling experimental apparatus. Through comparing and analyzing the results,the authors find the principle of causing errors and the ways to reduce errors in the experiment. This study provides gist for experiment operators and teaching reference for teachers.更多还原
