简介：保护的铬涂层被采用包装硬化在P110钢上准备。在浸透CO2的模仿的油矿盐水的P110钢和获得的涂层的腐蚀行为被静态的完全的沉浸测试和电气化学的大小学习。样品的腐蚀攻击被电气化学的大小的集体损失，侵蚀的表面形态学，腐蚀产品，和结果决定。试验性的结果证明涂层一致、连续、紧缩。铬涂层稍微被侵蚀，并且涂层的集体损失和腐蚀率是比P110钢的那些远低的。铬涂层比根据电气化学的测试的P110钢结果的有更高自我侵蚀的潜力和更低的腐蚀水流密度。总体上拿，渗铬处理显著地改进了P110钢的腐蚀电阻。

简介：在从Libixia节的Jialingjiang形成的破裂的大多数静脉mineralsdeposited，Hechan区域包括大量僵绳白云石和伴随的天青石，方解石和荧石。这研究分析了性质，来源，由飞机光岩相学的液体的进化，液体包括方法，阴极射线发光图象，和稳定的同位素的作文。在白云石的二阶段的水的液体包括的homogenization温度在100和270°C之间变化。与δ18O数据，为破裂屑的降水负责的液体有δ18在10‰之间的O值并且18‰(相对降雪)。僵绳白云石和伴随的矿物质是在提高的温度的稠密的盐水的活动的结果。而且，液体从导出水兵的盐水的混合物被导出并且更深传播的分析表演流动。这液体在成岩作用期间在Sr被充实并且在骨折并且为地区性的矿化作用形成了天青石。僵绳白云石的溶解被归因于冷却Mg/Ca-decreased液体，它可以联系到一在包围碳酸盐石膏沥滤到天青石。
