化工原理实验中双纵坐标图的绘制方法

Drawing Methods of Double Y Coordinate Graph for Experiments of Chemical Engineering Principles

化工原理实验数据处理过程中经常会碰到双纵坐标图的绘制,文章以Excel和Sigmaplot工具为例,针对离心泵特性曲线的测定实验数据,分别介绍了双纵坐标图的绘制方法。学生通过对绘图工具进行多方面、多层次的深入学习,进一步加深对实验数据的分析能力,提高数据处理技能。

In theprocess of experiment data processing of chemical engineering principles,two vertical coordinategraphs are often encountered.This paper introduces respectivelythe methods of Double Y Coordinate Graph withExceland and SigmaPlot tool as examples,for the experiment data of determination of characteristic curve of centrifugalpump.The students can further deepen the analysis of experimental datas and improve the data processing skills throughmulti-level and in-depth study of drawing tools.
