摘　　要：应用脉冲回波重合法 (pulse -echo -overlapmethod) ,在 0～ 40℃温度范围内 ,精确地测量了NH3 水溶液 (氨水 )中超声波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。The travel time of ultrasonic wave in NH 3 solutions at the temperature from 0 to 40 ℃ has been measured by the pulse-echo-overlap (PEO) method. The ultrasonic velocities and their first-order and second-order temperature-coefficients have been calculated.

关 键 词：超声波 氨水 速度 温度系数
