通过蔗糖水解反应速率常数测定的具体实例,应用Origin8.0软件提出了两种改进方法：非线性自定义拟合法和拟合模型对比法。结果表明,与传统方法相比,两种改进方法无须精确测量蔗糖完全水解的旋光度a∞,且改进的方法准确、快速、可靠,同时可获得手工绘图及用计算器计算难以获得的更大的信息量。因而该软件在物理化学实验数据处理过程中有良好的应用前景,为客观评价实验结果提供依据,同时具有良好的实验教学功能和效果。

Based on the concrete example of measurements of sucrose hydrolysis rate constant, this pa- per introduces two reformed methods, namely, user-defined nonlinear curve fitting and comparing models which are put forward for data analysis by Origin 8.0 software. Results showed that compared with the traditional methods, the new methods not only work without measuring the ultimate sucrose optical rotation（am）, but also are accurate, quick and reliable, and also obtain more information which are hard to be obtained by manual drawing and calculation of the calculator. Therefore, it is of significant importance in data processing of physical-chemistry experiment and has a bright future, providing for the basis of objective evaluation of experimental results and having favorable experimen- tal teaching functions and effects.
