浅析简谐振动的判断依据

The Judgment Analysis on Syntony

通过对简谐振动的判据 (或定义 )的分析 ,说明线性回复力为系统的内力、振动系统机械能守恒 ,是简谐振动系统的基本特征。指出在机械运动范围内 ,用振动的微分方程和运动学方程作为简谐振动的判据是不充分的 ,而且简谐振动是系统的振动 。

That linear reversing force was a civil force of the whole system and that vibrating system's mechanical energy was conservation were testified as basic features of syntonic system through the analysis of judgment conditions for syntony. It was pointed out that it was insufficient to take only differential equations of vibration and equations of kinematics as the judgment bases of syntonic vibration. The syntonic vibration was not a certain object but a whole system's movement.
