Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先，钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能，并且有明显的协同作用，从而能抑制部分点蚀核的产生；其次，钼酸盐复配缓蚀剂的使用，从电化学的角度分析，具有明显的钝化性能，且钝化区间较宽、维钝电流密度较小，从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化，得到有效的修复；最后，对于还有部分蚀孔发展成为闭塞腐蚀电池的情况，钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐，从而有效地减缓了点蚀的恶化，抑制了腐蚀的发展。

The fossil collections are important both scientifically and historically, with exceptionally well-preserved specimens from the Midlands and many other famous fossil localities in the UK, and throughout the world.The museum has some of the finest collections from the Wenlock Limestone of Dudley, famous for its fossils that lived 420 million years ago when the area was covered by a shallow, warm, tropical sea that enabled a highly diverse ecosystem to develop. From the rocks of the old Midlands Coalfields are important collections of fossil plants, fish, insects, arachnids, fossil footprints and animal tracks.

伯明翰大学的地质博物馆就在它的主楼里，不大，也不需买票，里面还免费提供小食品和饮料，但是展品很全：始祖鸟、鹦鹉螺、暴龙头骨、小昆虫和像钉子一样的不知名海底生物的化石，金、银、铜、硫的天然单质矿石，和一些由任何一本参考书上都没说过的复杂化学式所代表的成分所组成的宝石（我到今天才知道碱式碳酸铜的结晶原来这么漂亮），还有一些只听说过的铁酸盐晶体，当然馆内远远不止这

The electrochemical experiments show that the higher content of electric agent is helpful to increase the discharge efficiency of ferrates. But K_2FeO_4 is unstable and decomposed in the wet state during preservation in seal.

电化学测试实验表明，较高的导电剂含量对提升高铁酸盐的放电效率有利，但是湿态K_2FeO_4不稳定，在密封存放下会自发分解。

And iron content in milk in very small and some food as a result of the iron has oxalate, carbonate salts and plants and so on, can interfere with iron absorption and utilization, resulting in iron deficiency anemia.

而铁元素在奶类中含量很少并且有些食物中的铁由于有草酸盐，碳酸盐和植物酸盐等，会干扰铁的吸收利用，因而造成缺铁性贫血。

But ferrate has the property of self-catalysis, unlike the stability of chlorine, which contributes to its low stability in solution and prohibits its wide use.

但是，高铁酸盐有自催化现象，具有不稳定性，不能够象液氯一样长期保存，这大大限制了它的大规模应用。
