摘要
常见的物理化学实验的数据大概可以分为线性拟合,多项式拟合,分段数据拟合等。应用origin8.0软件对双液系气-液平衡相图做线性拟合得出直线方程,再绘制相图,对燃烧热的测定实验进行分段拟合等。相比于传统的方法,软件处理数据简便、快速、直观合理、准确性强等特点,在物理化学实验的教学中发挥了极大的作用。
Data handling of normal physical chemistry experiment can be classified into linear equation,polynomial equation and equation with range.Making linear equations and giving the graphics for the experiment of doubleliquid gas-liquid equilibrium and combustion heat by using the software of origin 8.0 was studied.It was rather convenient,fast,accurately compare with the tradition method and played a important role in the experiment teaching.
