用表面镀膜动态测量系统研究表面热电偶的工艺特性

The Study for the Technological Characteristics of Surface Thermocouple by Using a Dynamic Filming Measuring System

借助于一种表面镀膜动态测量系统，实测了不同头部结构及膜材的表面热电偶的Ｒ—δ关系曲线，并得出了评价表面热电偶优劣的若干结论。

By means of a dynamical filming measuring system specially designed for studying the relationship between filming thickness and its electric resistance of surface thermocouple, this paper measured the R—δ function and got some conclusions refering to judge the advantages and disadvantages of surface thermocouple.
