摘要
应用脉冲回波重合法（Ｐｕｌｓｅ—Ｅｃｈｏ—ＯｖｅｒｌａｐＭｅｔｈｏｄ），在４０－９０℃温度范围内，精确地测量了氢氧化钠（ＮａＯＨ）溶液中超声传播时间随温度的变化关系，并由此计算了它的超声波声速及其一级、二级温度系数。
The travel time of ultrasonic wave in NaOH solution at the temperature from 40 to 90 degree centigrade has been measured by the Pulse-Echo-Overlap (PEO) method. The ultrasonic'velocities and its first-order and second-order temperature-coefficients have been calculated.
