摘要
指出了分析判断简谐振动时易被忽视的一个问题,给出了简洁明了的分析方法和实例,进而明确了一定振动系统的运动性质与坐标原点选择无关,以及振动系统的能量守恒与势能零参考点的选择无关等基本结论.
A frequently neglected problem in harmonic oscillation analysis is pointed out, and simple analysis methods and solutions for some given oscillation systems are given. Some basic conclusions, such as the kinematic properties of a given oscillation system is independent on the origin of the selected coordinate system, the energy conversation of the system is independent on the selected referent zero-level of potential energy, are further confirmed.
