实验数据计算复杂,还要将结果在直角坐标纸上作图,主观误差不可避免。故以Visual Basic 6.0语言为工具,用最小二乘法直线拟合,处理化工原理实验“传热综合实验”的数据,以消除手工作图的误差,绘制出科学的、准确的图形。该程序占用内存小,使用快捷方便,经编译可生成脱离Visual Basic单独运行的可执行程序。同时可作为教师批改实验报告的依据。 Computational experimental data is complex, but also the results in Cartesian coordinates mapping, subjective error is inevitable. Therefore, the use of Visual Basic 6.0 language as a tool, using the least squares linear fit, dealing with chemical theory experiment “heat transfer synthesis experiment ” data to eliminate the error of manual mapping, draw a scientific and accurate graphics. The program takes up little memory and is fast and easy to use, and can be compiled to produce executables that run independently of Visual Basic. At the same time as a teacher to modify the basis of the experimental report.
