钢含碳的成分越多，冷却得越快，那么钢就越硬。
The more carbon the steel contains and the quicker the cooling is, the harder the steel becomes.
岩性主要为砾岩、泥岩、碳质泥岩、硬脆性泥岩、玄武岩、泥化玄武岩、石英岩及花岗岩等。
The lithology consists of conglomerate, shale, carbonolite, hard brittle shale, basalt, pelitized basalt, quartzite and granite, etc.
例如，能剪切极硬线的省力型斜口钳应该由0.8%碳和一定成分的铬和钒制成。
Can cut very hard line energy type, for example, diagonal cutting pliers should consists of 0.8% carbon and certain components made of chromium and vanadium.
结果表明：对于碳含量有差异的钢板，其显微组织、晶粒度及夹杂物等级均属正常，焊缝中未发现淬硬组织；
The obtained results indicate that the microstructure, grain-size and inclusion level of said steel plates were normal, hardened structure induced from quench had not been found;
中国石油兰州石化公司合成橡胶厂将碳四、苯乙烯、丙烯腈-丁二烯-苯乙烯嵌段共聚物等装置的凝结水收集后，先用于丁腈硬胶聚合用盐水的加热，换热后的回水再用于凝聚和洗涤用水；
The condensed water from plants of C4 , styrene and ABS was recycled and applied to heat salt water in production of acrylonitrile-butadiene rubber, and then used for agglomerating and washing.
