用自由落体仪测重力加速度实验的研究

Studies on the Measuring Instrument of the Acceleration of Gravitation by Freely Falling

本文在对自由落体仪做深入研究的基础上，指出了用自由落体仪侧重力加速度实验的主要误差来源和仪器存在的问题，给出了减小误差和改进仪器的办法。

After deeper studies on the measuring instrument of the acceleration of Gravity by Freely Falling, the main source of errors is analysed, and some methods of reducing errors and approving the instrument are given.
