晶体形成和溶解周期的监测为控制结晶过程中制备母溶液的溶质浓度和溶液温度提供了重要信息。本文将石英晶体传感器直接监测技术应用于溴化钾溶液结晶过程的监测，并对其监测性能进行了研究。实验结果表明，监测显示了晶体形成和溶解的详细过程，第一次测量的结晶形成起始温度与溶解完成温度之间存在0.98℃的滞后。此外，该技术的应用对于结晶过程的控制也是简单有效的。
Monitoring of the cycle of crystal formation and dissolution gives important information for manipulating solute concentration and solution temperature for the preparation of mother solution in crystallization processes. In this study a direct monitoring technique using a quartz crystal sensor is applied to the crystallization of potassium bromide solution, and the monitoring performance is investigated. The experimental results indicate that the monitoring shows the detailed process of crystal formation and dissolution, and there is a hysteresis of 0.98 degreesC between the initiation temperature of crystal formation and the completion temperature of dissolution in the first measurement. In addition, it is demonstrated that the application of the technique is simple and efficient for the control of crystallization processes.
