摘 要: 介绍了多管落球法测量重力加速度的新方法。采用外推法设计实验,实现了斯托克斯公式所要求的横向和纵向均为"无限广延"的条件。测得的重力加速度值与公认值相比相对误差为2.3%。 A new method for measuring the acceleration of gravity is proposed. The extrapolation method was used to design experiments. The conditions of infinite extension in the horizontal and vertical directions re-quired by the Stokes formula are satisfied by using extrapolation method. The ideal value of the acceleration of gravity is obtained. The relative error between the calculated and the standard values is 2.3 %.
