摘要
由能量方程出发,用换元的方法推导出三线摆大角度摆动时的周期的近似公式,并通过计算,确定运用该法所得的周期值更为精确.
In this article, based on energy equation the approximation formula of large angel trifilar pendulum period is deducted using the method of substitution. Through calculation it is found that the periodic quantity got through this formula is more accurate.
