摘要
采用超声多次脉冲回声法研制了一种高精度声速测量装置,测量误差小于0.4‰。可用于溶液及生物试样的迅速测量。
The development of sound velocimetry with high accuracy is described by using ultrasonic multiplicate pulse echo method. The device can be used to measure fast the ultrasonic velocity of the solutions and the biological test samples. Its measuring erros is better than 0. 04%.
