摘要
本文论讨了在实验室里用单摆测重力加速度时,摆球的大小对测量结果的影响,指出摆长在一米左右,摆球直径在二厘米时,由摆球大小带来的误差,出现在重力加速度的第五位有效数字上。
This paper discussed the problem of determining the acceleration of gravitywith pendulum in the laboratery. Author indicated the error that ditermining by size ofpendulum ball will take place in fifth significant digits in case it is a Metre in pendulumlength and 2 Centimetre in Diameter.
