摘要: 采用级数展开的方法,对《一个单摆周期近似公式》一文中所给出的近似单摆周期公式提供了理论依据,并且还可以得到精度更高的近似公式;同时,通过与其他近似公式的对比,说明该近似公式的精度可提高1-2个数量级.

关键词: 单摆, 周期, 近似解

Abstract: Based on the series expansion, we give a theoretical foundation for the approximate period formula of a simple pendulum which proposed in Ref. [ 8 ]. With this method, we propose a higher precision formula. In comparison with other approximate expressions, the accurate degree of the present formula is increased about 1 - 2 or- der of magnitudes.

Key words: simple pendulum, period, approximate formula
