摘　　要：文章采用Origin 8.0软件对经典物理化学实验"溶解热的测定"的实验数据进行处理,利用一次单减指数函数y=A1exp(-x1/t1)+y0拟合出溶液热Qs～n0曲线方程,并通过在拟合曲线上添加指定数据点、编写简单脚本语言的方法绘制出指定点的切线方程。该方法获得的实验结果误差小,图形美观,极大的提高了学生自行处理实验数据的能力。Origin software 8. 0, a powerful, fast and convenient application of multiple files interface, was widely applied to data analysis and graphic plotting. The software was used to process the data collected from the measurement of solution heat in physical chemistry experiment. The method not only drew the accurate solution heat curve, but also successfully found need points and tangent equation through certain points by using scripting language. As a result, using this software can diminish the error during data processing, make graphics more beautiful and easy to use. What＇s more, it improved the ability of data processing and composite qualities of students greatly.
