The fire zones are generally divided into five zones: flame zone, high temperature thermal plumes zone, fresh air supplement zone, transitional zone and "inert zone".
一般可分为燃烧区、新鲜空气补充区、烟气流区、过渡区和火焰后面的“惰化区”五区。
The conversion zone is continuously purged, preferably with an inert gas such as nitrogen.
转换区不断清除最好的惰性气体，如氮。
Surface roughness of hardened zone of the ball head pin has been improved on by the use of inert gas …
在感应加热过程中采用惰性气体和改进的工装夹具改善了淬火区的表面粗糙度。
