摘要
依据ＯｍｅｇａＥｎｇｉｎｅｅｒｉｎｇＨａｎｄｂｏｏｋ中的钨铼５－钨铼２６热电偶分度表和Ｓａｎｄ－ｓｔｒｏｍ＆Ｗｉｔｈｒｏｍ提供的钨铼５－钨铼２６热电偶在－２４０～０℃校正数据，对钨铼５－钨铼２６热电偶在－２４０～２３００℃进行了多项式拟合，偏差为±１℃。提供了热电势步长为０．１ｍＶＷ５％ＲｅｖｓＷ２６％Ｒｅ热电偶的分度表。
The thermocouples of the Tungsten 5% Rhenium Tungsten 26% Rhenium were calibrated from -240 to 2 300 ℃ by polynomial fitting methods,according to the table on the Omega Engineering Handbook and the data for -240￣0℃ by Sandstrom & Withrom.The accuracy is ±1 ℃,and a table of W5%Re vs W26%Re by 0.1 mV step is also provided.
