Both conditions can be detected by a temper etch (i.e., nital etch) inspection of the base metal.

两种情况在对本体金属的回火蚀刻检查中会发现。

What is obtained with the forging waste heat normalizing and controlled cooling technique is the coarse stable structure in a 20CrMnTi gear, but its cutability is good.

余热正火和常规的正火处理后，再经同样的工艺进行渗碳、淬火和回火处理，试验证明：其渗层和心部的组织、晶度及机械能均相同。

Two other poses were tried and I emerged from the booth to find photos of me as Indiana Jones, a fireman from Backdraft and a wrestler being strangled in a headlock.

又试了两个其它的姿势后，我从拍照亭里出来，看到了我扮印第安纳·琼斯的照片一《回火》中的一个消防队员和一个被紧紧卡住脖子的搏斗者形象。
