摘　　要：在利用超声光栅测液体声速的基础上,针对不同浓度的食盐(NaCl)溶液,研究超声波声速与溶液浓度的关系,并由此得出液体体积弹性模量与浓度的关系。实验结果表明,食盐(NaCl)溶液浓度与其体积弹性模量成近似线性关系。Aiming at the different concentration of the salt solution（NaC1）,this paper researches the relation-ship between velocity of ultrasonic wave and the liquid concentration based on measuring the velocity of ultra-sonic wave in liquid by using the ultrasonic grating. The relationship between liquid bulk elastic modulus and the liquid concentration is obtained. Experimental results show that the relationship between the concentration of the salt solution（NaCl） and the liquid bulk elastic modulus is a almost linear.
