利用超声光栅测量液体中的声速,是大学物理实验中的重要内容.根据多年教学经验,提出了超声光栅测液体中声速实验的改进方法,并与原方法进行了对比,实验结果比原来的方法在效果上有明显提高.%An improvement of experiment on measurement of sound velocity in liquid by ultrasonic grating was proposedrnin this paper. A comparison between the old method and the novel method showed that the novel method is morerneffective.
