We have found that The content of water and iron is the main cause of the phenomenon of collapse of the electric field of the electric dehydrator. The natural surfacants, polymers and colloidal FeS particles are the key cause of the form of the oil-water intermediate layer of the 4th Produced Factory.

Thermodynamic process of direct aluminium extraction from aluminium sub-sulphide, which is unstable and easily decomposed into Al and Al2O3 at a low temperature, was analytically studied. The temperature, at which alumina, FeS and carbon react to form aluminium sub-sulphide in different pressure, was evaluated with "Substance Gibbs' Free Energy Functional Determinant" method.

本文利用铝的低价硫化物在高温下存在，低温下不稳定容易分解得到金属铝的特性，从热力学角度引入"物质吉布斯自由能函数法"讨论在不同压力下，氧化铝、硫化亚铁与还原剂碳的反应生成低价硫化物的条件。

It was investigated the effect of mass ratio of TFIPS and ammonium chloride, the concentration and acidity of dissolution agent, temperature, and reaction time on the efficiency of dissolution.

用THPS配合氯化铵清除油罐中沉积的硫化亚铁，介绍了THPS在溶解硫化亚铁方面的实验结果，包括THPS与氯化铵的质量配比，溶解液的浓度和酸度，以及反应温度、反应时间。

A third example is the ferrous sulphide which we mentioned in the previous chapter.

第三个例子是前章提到的硫化亚铁。

公司目前生产柱式和扣式的锂/二氧化锰、锂/亚硫酰氯、锂/二硫化亚铁电池规格齐全。

The iron sulfide cleaning formulation with the surfactant, allene diamine, citric acid and EDTA as the main ingredients could react rapidly with the iron sulfide to form ethylene and element sulfur in the presence of catalyst.

一种以表面活性剂、丙二烯二胺和柠檬酸、EDTA为主要组分的硫化亚铁清洗配方，在催化剂存在的条件下能迅速与硫化亚铁发生反应，生成乙烯和单质硫。

There was large amount of ferrous sulfide deposited on the top of the reactor. The strong exothermal effect during the oxidation of the deposited carbon and ferrous sulfide caused 'hot spot' near the top of the reactor, which makes the temperature runaway easily.

结果表明，由于加氢脱硫反应器底床顶部沉积了大量的硫化亚铁，氧化再生过程中，催化剂上的积炭，沉积的硫化亚铁等均放出大量的热量，使反应器顶部产生热点，并可能造成飞温。

The number of autoterophic bacteria were significantly lower than the heterotrophic bacteria. Majority of 21 strains of heterotrophic bacteria that isolated from water body were Pseudomonas. Majority of 25 strains of heterotrophic bacteria isolated from sediment were bacillus, microccus and Pseudomonas.Three genus of autotrophic bacteria were sulphuret bacteria, nitrify bacteria and nitrosobacteria that were capable of oxidizing H2S, S, FeS, oxidizing NH3 to NO2 and NO2 to NO3 respectively.

试验稚鳖池水中共分离出21株异养细菌，其中优势菌为假单胞杆菌属细菌；底泥中共分离出25株异养细菌，其中优势菌为芽胞杆菌属细菌，微球菌属细菌假单胞菌属细菌，三种自养细菌分别为具有氧化硫化氢、元素硫或硫化亚铁的硫细菌；具有氧化氨为亚硝酸的亚硝化细菌和能将亚硝酸进一步转化成硝酸的硝化细菌。

Copper is present in the earth's crust mainly in the form of sulphide minerals, often in conjunction with iron sulphide FeS.

铜主要是以硫化矿物的形式存在于地壳中，并常常与硫化亚铁并存。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
