摘要

声源与接收器之间存在相对运动就会发生多普勒效应。目前，许多高校物理实验室使用的多普勒效应验证仪器只能验证接收器和声源在一条直线上时，接收频率与接收器运动速度的关系，对于声源运动以及相对运动与二者连线存在角度等情况还不能验证。因此，为了全面验证多普勒效应，在原装置的基础上进行了一定程度的改进，新的实验装置可以弥补原实验装置的不足。通过对实验数据的处理分析，计算出声速的相对误差在３％左右，验证了本实验装置的可靠性。

关键词: 多普勒效应接收频率速度角度

Abstract:

The Doppler effect occurs when there is relative movement between the sound source and thereceiver.At present ,the Doppler effect verification instrument used by many university physics laboratories canonly verify the relationship between the receiving frequency and receiver motion speed when the receiver movesin a straight line with the sound source. and cannot verify the angle between the sound source movement andthe relative motion and the connection between the two.Therefore ,in order to fully verify the Doppler effect,acertain degree of improvement has been made on the basis of the original device , and the new experimentadevice can make up for the shortcomings of the original experimental device.Through the processing andanalysis of the experimental data ,the relative error of the sound velocity is finally calculated to be within 3%which verifies the reliability of the experimental device.

Key words: Doppler effect receive frequency velocity angle
