摘要
讨论了在弹簧振子质量不可忽略的条件下,弹簧振子系统振动固有频率的精确解.与通常大学物理实验中引用的弹簧振动固有频率的瑞利近似关系相比较,进而得到该近似关系的应用条件.
This paper derives the precise solution about the inherent frequency of the mass-spring system when the mass of the harmonic-spring is not negligible. The derived solution is then compared with the Rayleigh approximate relation which is usually employed in physical experiment of college, and the available condition for the approximate relation is obtained.
