在最大气泡法测定溶液表面张力的实验中,用VC++6．0开发了溶液表面张力联机检测处理软件,实现了微机与DP- AW精密数字微压差计之间的数据通讯、压差-时间曲线的自适应滚动显示、表面张力-浓度关系的非线性拟合和表面吸附量-浓度关系的快速获取。该软件已在教学中使用。使用结果表明,该软件计算数据准确、操作方便灵活、用户界面友好,可作为为计算机辅助教学的有力工具。
In the experiment of measuring the surface tension of the solution by the maximum bubble method, the online detection and processing software of the solution surface tension was developed by using VC ++ 6.0 to realize the data communication between the microcomputer and the DP-AW precision digital micro-differential pressure meter. The pressure difference - Adaptive scroll display of time curve, nonlinear fit of surface tension - concentration relationship, and rapid acquisition of surface adsorption - concentration relationships. This software is used in teaching. The results show that the software is accurate, easy to operate and user-friendly and can be used as a powerful tool for computer-assisted teaching.
