| 摘 要： | 用数学、力学的一般讨论方法,说明谐振动就是动、势能在平衡位置附近相互转化,并用算例重点论证了对于谐振系统,其坐标系原点和势能零点一般只能选在这个谐振动系统的平衡位置上,而非一般力学问题可任意选取.为解决物理教学上的难点,提供一个选择方案.

| Abstract: | Through the mathematical and mechanical methods,puts forward that harmonic vibration is converted by the balance point of active energy and potential energy and explains with example that as to the system of harmonic vibration,origin of coordinate and zero-point of potential energy can only be selected at the balance point of the system of harmonic vibration.So it brings forth a selection for solving the difficulty in physics teaching. |

| Keywords: | harmonic vibration potential energy balance point |
