掺杂WRe3、WRe25合金的高温电阻－温度特性

Characteristics of Electrical Resistance-Temperatl1re of Doped WRe3 and WRe25 Alloy at High Temperature

本文报导了采用一种新型高温陶瓷发热体高温管状炉，通以氩气保护，测量ＷＲｅ合金丝的电阻－温度（１６００℃）特性试验方法，该方法较真空炉简便、实用且试验费用低而准确，测量数据与美国研究报导一致。

This paper has reported an experimental method which used a new high-temperatureceramic heat elen1ent,a hish-temperature tubularfurnace,as the heat resource,with sealed and Ar-gon protecting devices to measure the electrical resistance teniperatre(1600℃)characteristies ofWRe alloy filaments.This method is simnple,practical and precise,and its experimentai expense islow. The measuring data are consistent with thedata in the research paper of the United States.
