摘要
通过对FD-DB-Ⅱ型单摆实验仪的研究,对该装置作了改进,增加了可计算振幅的刻度板,并使用电磁铁控制摆球的释放,由此可以研究周期T和角振幅θ0的关系,也可利用T-（sinθ0/2）~2 曲线外推后计算重力加速度g.
FD-DB-Ⅱ single pendulum experimental instrument was improved,a scaled plate which can be used to compute the vibration amplitude was added,and an electromagnet was adopted to control the release of the balance ball.The improved instrument can be used to explore the relation between period and angular amplitude and to obtain the acceleration of gravity by calculating T-（sinθ0/2）~2 curve.
