科学实验室系统是由美国 PASCO 公司研制的计算机实时测量系列实验设备，其特点是利用不同类型的传感器实现对多种物理量的量化测量与分析。本文利用 PASCO 系统和转动传感器记录了波尔共振实验仪摆轮的实时运动状态，得出阻尼系数β值以及幅频特性和相频特性曲线，并观测受迫振动中的耦合过程。

Science Laboratory System is a kind of real-time measuring laboratory equipment developed by PASCO Company of U.S.A.With the help of different kinds of sensors,the system permits quantized measurement and analysis of various physical quantities.In this pa-per,we extended the traditional methods and analyzed the real-time motion of the balance wheel comprehensively by using the rotation sensor and the PASCO system.We obtained the damping coefficientβ as well as the curve graphs of amplitude-frequency and phase-frequency. Besides,the real-time measuring function made it possible for us to observe the motion of the balance wheel with different values of the damping coefficient,and thus enabled us to success-fully record the process of coupling under forced oscillation.
