Origin软件在实验数据处理中的应用研究

Application Research of Software Origin in Experimental Data Processing

随着计算机科学的普及与提高和学生对数据处理软件的广泛应用,在处理实验数据过程中让学生用线性、非线性、指数等多种函数程序对测量数据进行拟合处理并加以比较分析,使其在同等实验条件下得到最为精确的经验公式是一种较好的途径。本文在大量实验测量的基础上,基于数据处理软件Origin,采用不同计算方法对蓖麻油表面张力与温度关系实验的测量数据进行了处理,通过对实验结果进行比较分析得到了更加精确地经验公式,减小了实验误差找到。

With the popularity of computer science and the wide application of data processing software,it is a good method to let the students to use linear,nonlinear,or exponential function to fit the measured data and to make comparative analysis in the process of data processing program. It can makes students get the most accurate empirical formula with the identical experimental conditions. In this paper,we apply the data processing software Origin,and use different calculation methods to establish the relationship between surface tension and temperature for the Castor Oil.Through the comparative analysis with the result of the experiments,students can get the more precise empirical formula,and find a better way to reduce experimental error.
