超声波测定盐湖卤水的密度

叙述了超声波在与盐湖卤水组成相关的 Mg Cl2 溶液、Na Cl溶液、Mg Cl2 和 Na Cl的混合溶液中的声时与溶液浓度、溶液温度等之间的关系 ,测定了察尔汗不同蒸发阶段的盐湖卤水密度、声时和温度值 ,并针对察尔汗盐湖卤水组成 ,将获得的实验值采用拟合及插值的方法编制成计算机程序储存在单片机中 ,从而实现了察尔汗盐湖卤水蒸发过程中密度的自动监测

Density Monitoring of Brine of Qarhan Salt Lake by Ultrasonic Technique

The variations of ultrasonic transit time in a series of MgCl 2 solution and a series of NaCl solution were measured from -10°C to 35°C. The relations between concentration, temperature and transit time were discussed. Values of density, temperature, and ultrasonic transit time, based on the composition of brine of Qarhan Salt Lake, were also determined during evaporating of brine at Qarhan Salt Lake. Finally fitting and interpolating of a polynomial with the measured values were used to design the program as a part of automatic monitoring system for Qarhan Salt Lake.
