摘　　要：对实验室现有的超声光栅测声速实验装置加装反射镜及利用激光光源进行改进,通过对样品纯净水的测试比较,改进后的实验装置对实验测量结果精度有明显提高。测试样品的范围扩大,实现了物理实验技术和方法与石油专业相结合,有利于提高实验教学效果。It ameliorated the existing laboratory device of ultrasonic grating measuring sound velocity equipped with mirror and using the laser light source. By analyzing the test results of the sample purified water,the accuracy of the measurement results have improved obviously. That,which expanded the range of test samples,realized a physical experimental techniques and methods in conjunction with petroleum professional,was helpful to improve the effect of experimental teaching.
