摘要
重力加速度测量实验中,通过对实验进行设计与改进,消除由于传感器触发及摆线固定端等问题带来摆长与摆动周期测量的误差,并采用录像和Vegas、Origin等软件进行测量和分析摆动状态,实验结果表明,改进后减少了误差的引入,提高了实验测量的精确度.
In the experiment of measuring the gravity acceleration, through the improved ex- perimental design, we eliminated the metrical errors of the pendulum length and the swing pe- riod brought from the sensor triggers and the fixed end of cycloid. Video and some software such as Vegas and Origin were used to measure and analyze the swing state. Experimental re- sults indicated that the improved experimental design reduced the introduction of errors and improved the accuracy of the experimental measurements.
