单摆周期近似解法综述
Several approximate calculations of the period of a simple pendulum
【摘要】 以求解单摆运动周期为例,首先给出单摆周期的经典解法,然后介绍4种近似的解法,与传统的解法相比具有简单实用的优点.最后对各种情况得到的周期解用作图的方法加以比较.
【Abstract】 The classic solution of pendulum periods was presented and four approximate solutions were introduced.Compared to classic solution,these approximate solutions were showed to have advantage of simpleness and practicality.All kinds of periods discussed were compared by graphs.
