用Origin软件的线性拟合和非线性曲线拟合功能处理实验数据

Experimental Data Processed by Linear Regress and Nonlinear Curve Regress Using Software of Origin

以物理化学实验中《燃烧热的测定》实验为例,说明Origin软件在计算机上对实验数据进行作图、线性拟合和非线性曲线拟合等处理而求得需要的实验参数,从而大大减少数据处理过程中产生的误差,而且方便快捷。

According to the example of burning-rate＇s mensurationinthephysicalchemistryexperiments, experimental data were passed to computer for drawing, linear regress and nonlinear regress by means of software Origin. Final experimental parameters show the method is not only fast and convenient, but also greatly reducing error caused by data processing.
