比较电压 meaning in Chinese

comparison voltage

( 8 ) by studying match between the electronic system and catalytic converter on the base of electronic controlled bypassing air system , conclusions having been gotten as follows : higher conversion efficiency of emission have gotten when a / f fluctuates at definite scope and frequency , by controlling the comparing voltage of 02 sensor , the working scope of catalytic converter can be controlled and the matching that can fulfill the high efficiency of hc , co , nox at same time has been optimized
（ 8 ）进行基于所开发的电控补气系统上的催化器与电控系统的匹配研究，当控制系统调节空燃比在一定范围按照一定频率进行波动时，可以提高催化转化器的转化效率；通过控制氧传感器的比较电压，可以控制催化转化器的工作窗口，实现排放污染物中， hc 、 co 、 nox转化的最优匹配。
