摘要
从 RLC串联电路方程及其初始条件出发 ,推导出电路欠阻尼状态下阻尼电阻与振幅、阻尼度之间的关系式 ,用最小二乘法对测量数据进行线性回归 。
A method of determining the critical resistance is introduced from the relevant equation and the initial condition of the RLC series circuit. In the deficient damping resistance, the damping resistance formula, which is related with the vibration amplitude and damping ratio is derived, and the least square method is used to fit the experiment data.
