【摘要】 介绍了采用超声光栅效应测量液体体积弹性模量基本原理,设计组装了实验测量装置,测定了在不同矿化度下液体体积弹性模量。根据实验数据分析了液体体积弹性模量的变化规律、在同一温度时水溶液体积弹性模量随着矿化度的变化规律。实验表明:随着矿化度的增大,液体体积弹性模量会先增大后减小。更多还原

【Abstract】 Introduced the basic principle of the measurement of liquid bulk elastic modulus adopting ultra phonic raster effect,designed and assembled the experimental equipments of measurement,evaluated the liquid bulk elastic modulus at variation law salinities.According to the experimental data analyzed the changing law of liquid bulk elastic modulus and analyzed the variation law of liquid bulk elastic modulus with the changing of salinity at the same temperature.Experiments showed that Liquid bulk elastic modulus will first increase then decrease along with the increase of salinity.更多还原
