摘　　要：如何正确应用振动旋转矢量和空间(波动)旋转矢量研究平面简谐波的问题,是大学物理教学中的一个重点问题.在系统对比分析两种旋转矢量的基础上,从波函数和波形图两方面比较分析了两种旋转矢量在描述平面简谐波上的异同,归纳了应用两种旋转矢量解决平面简谐波问题时应注意的问题.结果表明,应用两种旋转矢量都能较大程度地降低分析解决平面简谐波问题的难度.在应用时,应说明旋转矢量的类型和注意其特征,避免混淆出错.How to correctly use the vibration rotation vector and the spatial(wave)rotation vector to study the problems of plane simple harmonics is a difficult problem in the teaching of university physics.By comparing the two rotation vectors in detail,analyze the similarities and differences between the two rotations in terms of wave function and waveform graph,and summarize the considerations for using two rotation vectors to solve the problems of plane simple harmonics.The results show that the application of the two rotation vectors greatly reduce the difficulty of solving the problems of plane simple harmonics.When applying,the type of rotation vector should be specified and its characteristics should be noted to avoid confusion and errors.
