恒压供电单桥恒温式燃气检测电路“双桥恒温式燃气检测方法”补述

摘要

“双桥恒温式燃气检测方法”［1］文，声称“恒温方式检测燃气量电桥，不宜采用传统恒压供电的单桥电路”之说，不够全面.特提出“恒压电单桥电路”，予以补充，以求得对电桥电路对称性有一完整的概念.%The paper of "methane detection of thermostatic catalytic sensor with two bridges" professes that the mono-wheston bridge ckt in constent voltage source cannot apply to measure gas quanlity by thermostatic condition. It is a prejudice. From this opinion, this paper suppliments and presents a gas measurement ckt by mono-bridge in constant voltage source with thermostatic mode.
