本文是結合敎學工作進行研究的一個結果,提供了對不帶放大器的電阻應變儀基本電路的分析,包括(1)電橋各臂的電阻和檢流計的靈敏度與應變儀靈敏度的關係的計算;和(2)對不帶放大器的應變儀在製造和使用方面的限制的簡短討論。並提出對本刊第二期贾有權同志:“测靜荷的電阻式應變儀的設計和製造”一文的一些改進意見。
This article is a result of a study conducted in conjunction with the work of science and provides an analysis of the basic circuit of a strain gauge without an amplifier, including (1) the relationship between the resistance of each arm of the bridge and the sensitivity of the galvanometer and the sensitivity of the strain gauge Calculation; and (2) a brief discussion of the limitations in the manufacture and use of strain gages without amplifiers. And put forward some improvements on the article of the second issue of Comrade Jia Youquan: “The Design and Manufacture of Resistive Strain Gauge of Static Load”.
