摘要
介绍了旋转液体特性法测定重力加速度实验原理,用计算机origin软件对实验数据进行曲线拟合,得到了西安市区的重力加速度,并与当地公认数值做一比较,发现误差较小。
The principle of measuring acceleration of gravity is introduced by using a rotating liquid method, The data measured in the experiment are carried out curve fitting by the origin software, Xi＇ an urban gravity acceleration are calculated, and compared with the local accepted value, it found that the error is smaller.
