“BET容量法测定固体比表面积”实验数据处理程序

A method of data processing for the experiment of measuring solid specific surface area with BET capacity method

由于实验数据计算复杂并且需要根据其结果在直角坐标纸上作图,不可避免引起主观误差。以Visual Basic 6.0为开发工具,用最小二乘法直线拟合,处理物理化学实验"BET容量法测定固体比表面积"的数据,完全消除了手工作图的误差,得正确实验结果,绘制出图形。通过界面窗口将数据录入和数据处理功能相分离,避免了个别学生修改实验数据。该程序为实验的数据处理提供了方便的方法,也为教师批改实验报告提供了可靠的依据。

The subjective error was caused inevitably in the course of experimental data processing because of complicated calculation and drawing in the squared paper based on the results. Visual Basic 6.0 and a least squares straight line fit program are used to compile this software for the physical chemistry experimental data of measuring solid specific surface area with BET capacity method, and correct results including date and figures can be achieved. The functions of data input and data processing are separated, avoiding the students to revise the experimental data. This software not only provides a convenient way to deal with experimental data, but also provides reliable evidence for teachers to check up experimental reports.
