二组分相图制作研究

On the Drawing of a Two-component Phase Diagram

通过金属相图实验,应用Excel进行二组分图形绘制,把Sn-Pd二组分系统的相图分解成绘制三条线段.利用实验中所测量并经校正的转折温度与平台温度,分别设置系列1、系列2和系列3,再应用Excel相关技巧最终绘制出完美的二组分相图.

Through experiment of metallic phase diagram and by use of Excel, a commonly used data-processing software in experiments of physical chemistry, two separated diagrams were drawn and thus the Sn-Pd two-component phase diagram was decomposed into the drawing of three line segments. Then by the use of transition temperature and the constant temperature detected and adjusted in the experiment, Series 1, series 2 and series 3 were set respectively. Furthe, by application of relevant Excel skills, a perfect phase diagram of the Sn-Pd components was accomplished. The research not only helps students acquaint themselves with the relevant Excel data-processing skills, but also does good to a better understanding of the experiment so as to better realise the experiment＇s objectives.
