摘要
本文以蒸馏水和自来水为例,利用时差法测量了超声波在液体中的传播特性,同时给出了在不同温度下水中声速与温度的关系曲线图,对进一步研究液体中声速特性有一定的参考价值。
Tap water and distilled water is the example in this paper. Time difference method measured the sonic speed transmit characteristic in liquid. And given the relation graph of the velocity of sound and temperature of the ultrasonic in difference temperature water. Afford the reference for next study the characteristic of the ultrasonic.
