摘　　要：采用微机测控系统对盐类溶解热测定实验进行全程测控,代替了原来传统的手工操作。通过两种实验方法的比较,应用计算机技术进行联机检测,不仅操作简单,提高实验效率,而且可以在实验数据处理环节中尽可能的减少人为误差,得到较可靠的实验结果。由实验测得硝酸钾的积分溶解热为35.329 kJ·mol-1。The experiment of the dissolution heat of salt was measured of the whole course by computer control system. Compared to the traditional manual operation, through on -line examination carried out by the computer technology, the operation was not only simplified, the experimental efficiency was raised, artificial error in data analysis was moreover reduced as far as possible, and credible results were obtained. The integral dissolution heat of niter was 35. 329 kJ . mol^- 1 by the experiment.
