On the basis of characteristic analysis on all kinds of mineral tailings of copper lead zinc, mineral tailings was classifying according to its application. At the same time, the calcining experiment for twenty material prescriptions of the mineral tailings substituting the clunch or mineralizer mixed with different grades of limestone was actualized in the laboratory's heating kiln under the different temperature. After the fCaO analysis and the X-diffraction test to the calcined samples, the reasonable prescriptions and optimal calcining condition were put forward for different kinds of mineral tailings used to substitute the clunch or mineralizer, the research conclusion offers the instructional reference for the large-scale industrialization production.

同时，对尾矿用于代粘土和矿化剂配不同品位石灰石的20个生料配方进行了实验室高温炉不同温度下的煅烧试验，并对煅烧后的熟料样品进行了游离CaO和X衍射分析，得出了不同尾矿用于代粘土或矿化剂的合理配方和煅烧工况，从而为大规模产业化利用提供指导性参考依据。

The coral polyp is a kind of coelenterate in the ocean, it, in order to pray on the tiny planktonic organism in the ocean as the food, can absorb calcium and carbon dioxide in the sea water in the course of growing, then secrete out the lime stone, turn into the outer cover that oneself survives.

CFB clean coal power generation technology is a kind of combustion technology for power generation, it is the internal combustion in circulating fluidized bed boiler with coal particles, and at low-temperature combustion furnace conditions add to the amount of limestone achieve desulfurization, denitration cleanliness coal power generation technology.

CFB发电技术是煤清洁燃烧发电技术的一种，它是在循环流化床锅炉内燃用颗粒煤，并在低温燃烧状况下向炉内加入适量石灰石实现脱硫、脱硝的洁净煤发电技术。

The results showed that nitrogen oxide was strongly deoxidized to nitrogen by iron; Petroleum coke char and CO could promote the heterogeneous reaction of Fe and NO, deoxidize iron oxides, and prolong the active time of iron; while limestone had little effect on the heterogeneous reaction.

结果表明：Fe对NO有很强的还原作用；石油焦焦炭和CO对Fe与NO之间的多相反应具有很强的促进作用，可还原Fe的氧化物，延长Fe的作用时间；而石灰石对Fe与NO之间的多相反应几乎没有作用。

Now there is the development and utilization of gold, lead, zinc, iron, marble, granite, diabase, dolomite, limestone and so on.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
