不同频率的声波对测速的影响
The Relationship Between the Different Frequency of the Sound Waves and the Speed Measurement
【摘要】 探讨不同频率的声波对测速的影响,以利于我们在今后的测速方面选择合适的选频。实验中应用了多普勒效应原理及李萨如图形原理。
【Abstract】 The relationship between the different frequency of the sound waves and the speed measurement is studied in order to choose the appropriate frequency.The principle of Doppler effect and Lissajous figures synthesis principle are used in the experiment.
