摘  要:测定冰溶解热的实验持续时间短、温度变化快，通过水银温度计很难在较短时间内快速准确地完成多次测量。由此设计出一种测量冰溶解热的“数字实验”：利用自动温度采集系统测量出实验温度，通过用Visual Basic开发的实验系统软件对温度数据进行计算和散热修正，可以快速准确地完成实验，以及直观地显示出测量结果。

ABSTRACT:The experiment of measuring ice’s heat of solution always lasts for a short period and the temperature changes quickly. It is difficult to finish some measurements quickly and accurately in a short time with the Mercury thermometers. Considering these disadvantages, a " digital experiment " was designed to  measures ice’s heat of solution.The collection system of automatic temperature was applied to measure the experiment temperature.And the experiment data was calculated by a software of experiment system which was developed with the Visual Basic software. Then we can finish the experiment quickly and accurately, and show the result of measurement directly.

　　　随着社会的发展数字实验也越来越受到人们的关注和重视，如现在很多高校都正在建设以数字实验室为中心的各种实验室，大大提高了学校的教学效率。而且随着数字化实验室的产生，对实验室提高工作效率、降低运行成本起到很大的作用，这也正好符合目前国内绝大多数实验室的要求。很多工厂、企业都在逐渐建立以自动化的生产、管理和控制等为一体的现代化数字系统，达到自动化运行、信息化管理和无纸化办公的目的。数字实验对具有发展潜力的LIMS（实验室信息管理系统）产品就显得尤为重要。
