摘要
应用脉冲回波重合法（Ｐｕｌｓｅ－Ｅｃｈｏ－ＯｖｅｒｌａｐＭｅｔｈｏｄ）在３０～７０℃温度范围内，精确地测量了醋酸溶液中赵声传播时间随温度的变化关系，并由此计算了醋酸的超声波声速和一级、二级温度系数．
The travel time of ultrasonic wave in acetic acid at the temperatures from 30 degree to 70 degree centigrade has been measured by the PulseEchoOveriap (PEO) method. The ultrasonic velocity and its first-order and secondorder temperature-coefficienis have been calculated.
