A new type of effective complex coagulant polysilicate aluminum ferric salt was prepared from coal gangue awl pyrite slag and used as coagulant in the treatment of vegetable oil wastewater.

用煤矸石及硫铁矿烧渣作原料制备了一种高效复合混凝剂聚硅酸铝铁，并将其用于植物油脂废水的处理。

The mineralization-alteration in Shuangfengshan appears in downward succession of silica breccia zone, low grade gold-bearing silica rock zone, quartz stockwork zone, pyrite montmorillonite zone and propylitic alteration zone.

这两个成矿阶段同源同位的蚀变矿物晕叠套，造成双峰山矿床蚀变分带从上至下为隐爆矽质角砾岩化带、低金品位矽质岩带、石英网脉带、黄铁矿蒙脱石化带和青磐岩化带。

这两个成矿阶段同源同位的蚀变矿物晕叠套，造成双峰山矿床蚀变分带从上至下为隐爆硅质角砾岩化带、低金品位硅质岩带、石英网脉带、黄铁矿蒙脱石化带和青磐岩化带。

Total iron ion concentration in the slurry increased as the desulfurization reaction proceeded, which showed that the coal pyrite was being leached. This method can not only achieve high flue gas desulfurization efficiency but also reduce pyretic sulphur from coal.

随烟气脱硫过程的进行，脱硫浆液中的总铁含量不断增加，说明煤中黄铁矿被不断浸出，故此法在脱除烟气中的二氧化硫的同时也降低了煤中的黄铁矿硫。

On one hand we take the waste gypsum, pyritic slag as the main resources. Proportion is such as follows: scree 15%, pyretic slag 30%, waste gypsum 45%, cement 10%, then take the semi-dried method, high pressure moulding to produce the waste gypsum and pyrite cinder brick which resist pressure is over 100~# brick resist pressure.

实验一方面以工业废石膏和硫酸烧渣为主要原料，按石屑15%，硫酸烧渣30%，废石膏45%，胶结料10%；半干法高压成型，再自然养护，制成废石膏硫酸烧渣砖，强度达到100~#以上。

In order to solve these problems, supported by Foundation for University Key Teacher by the Minisity of Education, we study on distribution of sulfur in coal samples of ShenYang HongYang No. 3 coal mine and find that the sulfur in pyrite is more than 72％ in the total sulfur of the coal. The pyritic sulfur immerges in coal and is diffcult to be removed by common methods.

针对上述问题，我们在教育部高等学校骨干教师资助计划的支持下，以沈阳红阳三矿煤为试样，对其中硫的的赋存状态进行了研究，发现该试样中的硫有72％以上为黄铁矿硫，而且黄铁矿多数呈细小颗粒浸染于煤的有机质中，用常规分选方法脱除比较困难。

Oxidation of pyrite can significantly affect properties and the behavior of soil and rock in civil construction. Problems with pyritic rock and soil extend globally and across many disciplines.

本研究利用南岗工业区液化砂土，於室内制作35%、50%、90%三种相对密度的重模土壤试体，在三种不同有效围压下，分别进行排水与不排水静态三轴试验。

These experiment investigztions indicate: When coal is under high heating pyrolytic condition, the pyrite in coal decomposes very quickly, some amount of pyritic sulfur is transformed to organic sulfur and 〓 char, the volatile waterial in coal will restrain the transformation.

根据这一些试验研究得出：煤在快速热解条件下，煤中的黄铁矿的热分解极快，黄铁矿热分解的一部分硫转化成有机硫而存留在残炭中，煤中挥发份对这种硫的转化起抑制作用。

The chemical composition of pyrite, galena and sphalerite clearly shows that there are dual features of synsedimentary deposits and subma rine exhalation-sedimentary deposits in the ore formation in this area.

黄铁矿、闪锌矿和方铅矿的化学成分标型研究清楚地表明，本区矿石的形成具有同生沉积矿床和海底喷气一沉积矿床的双重特征。

The studies on mineral geochemical for Erdaogou gold deposit located in the west part of Liaoning province indicate that it is characterized by low temperature mineral association such as pyrite, chalcopyrite, galena, sphalenite, telectrum, quartz, seriate, calcite, adual etc.

通过对二道沟金矿床矿物学的详细研究和对比，表明该矿床低温热液矿物组合和低温热液蚀变十分发育；与典型的冰长石-绢云母型浅成热液金矿的矿物组合十分相似；其应属于与流纹熔岩及其火山碎屑岩密切相关的浅成热液型金矿床

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
