摘要
利用超声波声速测定仪测定出超声波在不同浓度NaCl溶液中的传播速度．实验给出，超声波在NaCl溶液中的传播速度与溶液浓度呈线性关系．溶液温度对超声波波速也有影响，并从理论作了分析研究，给出了合理的解释．
This paper further application of ultrasonic, the design gives ratio of different concentrations in solution NaCl solution, under the constant temperature conditions, using the ultrasonic supersonic velocity tester at different concentration the velocity NaCl solution. Experimental research, ultrasonic NaCI solution obtained in the transmission speed and strong NaCl solution concentration in a linear relationship. Different temperature on the NaCl solution ultrasonic wave may also be affected. From theory analysis and puts forward the reasonable explanation.
