简谐振动初相位表达式的研究

Research on the Expression for the Initial Phase of Simple Harmonic Vibration

简谐振动的理论内容见于诸多的振动力学和理论力学等书籍中,然而在关于简谐振动的初相位表达式上却存在着一个不易察觉的错误,本文指出和论证了这一错误,并在此基础上,给出了简谐振动初相位的正确表达式。

The content of simple harmonic vibration is presented in many books on vibration mechanics and theoretical mechanics. However, there is an imperceptible error in the initial phase expression of harmonic vibration, which is pointed out and demonstrated in this paper, and the correct expression of the initial phase of harmonic vibration is given.
