回火

"It is a strong oxidizing agent (see oxidation-reduction), used in fireworks, explosives, matches, fertilizers, glassmaking, steel tempering , and food curing; as a reagent; and as an oxidizer in solid rocket propellants."

硝石是一种强烈的氧化剂，被用于烟火、炸药、火柴、肥料、玻璃器具制造工业、钢铁回火以及食物保存处理，也被用作试剂和坚固的火箭推进物的氧化剂。

The result of impact particle abrasion test show that the best wearable material is 2C sample through glomeration anneal,850℃ oil quenching and 2 hours 300℃ tempers in selected 1#,2# and 3# wearable materials.

冲击磨料磨损试验结果表明，所选编号为1~#、2~#和3~#的三种耐磨材料，耐磨性能最好的是2~#材料在球化退火后，进行850℃油淬，300℃回火2小时的试样(2C试样)。

The annealing experiments with different processes and the saw cutting life test on machine hacksaw blade s made of W9Mo3Cr4V HHS are carried out.

对W9Mo3Cr4V高速钢机用锯条进行了退火工艺试验和锯切寿命试验，试验结果表明，不同退火工艺与锯条淬火回火硬度及锯切寿命之间不存在明显对应关系，但高温长时间退火对锯切寿命有不利影响。

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——《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。

The effect of heat treatment on the properties of high Cr-W cast iron was studied in this paper.

研究了热处理对高铬钨铸铁力学性能的影响，结果表明，高铬钨铸铁经980℃×2h空冷+400℃×2h回火处理可获得较高的力学性能。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
