论文部分内容阅读
本刊1980年第三期在“建议”栏里发表了“谈谈热电偶检定时冷端温度的修正公式”一文后,收到很多读者的来稿,对该文提出异议,一致认为作者对《0～1300℃工业用热电偶检定规程》的理解是不正确的,从而引出了错误的结果。我们同意这种看法。为了肯定上述规程的正确性以保证该规程的贯彻执行,我们从二十多篇来稿中选择一篇予以发表。文章以理论与实验数据作了验证,证明规程中的修正公式是正确的,在热电偶检定工作中,不应使用“改进公式”与“K值表”。
In 1980, the third issue of the “Suggestions” column published “to talk about thermocouple test cold junction temperature correction formula” one article, received a lot of readers contributions, the article raised objections, agreed that the author of “ 0 ~ 1300 ℃ industrial thermocouple test procedures, ”the understanding is not correct, leading to the wrong result. We agree with this view. In order to affirm the correctness of the above procedures to ensure the implementation of the procedure, we select one of more than 20 articles for publication. The article is validated by theoretical and experimental data to prove that the correction formula in the procedure is correct. In the work of thermocouple verification, “improved formula” and “K value table” should not be used.
