针对高二物理所学教材中的一段话(现行高二人教版教科书物理第36页):“振动系统受到的阻尼越大,振幅减小越快,振动停下来也越快”提出一些异议,并通过下文的分析提出了当阻尼达到临界状态时系统的振动是停下来最快的,无论是过阻尼还是欠阻尼都比临界状态停下来的时间要长。 A paragraph from the text of the physics of sophomore study (current Gao Erren textbook physics page 36): “Vibration system is subject to more damping, the amplitude decreases faster, the vibration stops faster ” made some objections , And through the following analysis, it is proposed that the system vibrates the fastest when the damping reaches the critical state, and both over-damping and under-damping will stop longer than the critical state.
