中文摘要：

通过控制变量研究了滚摆的扭动周期,发现扭动周期同单摆一样是一定的,其周期大小由摆轮半径R、双线悬点距离d1＋d2及摆长L决定;并从简谐振动规律出发理论上证明了扭摆振动周期公式;由此讨论了一系列不同摆动体的扭动周期公式以及作为引力波天线的可能应用.

英文摘要：

By studying period of twisting-pendulum concretely with methods of control variables,a conclusion is drawn that period depends on pendulum wheel radios R,space of two hanging points d1＋d2 and length of pendulum line L.Proving of formula of period is given according to simple harmonic vibration in theory.For different swilling-body on the axis,correspond period is also discussed,so it is with the possible applications on acting as the antenna of gravitational wave.
