Founded in 1886, was a prospector stations, with the gold after the discovery and exploitation of the rapid development of the city.

在东北部瓦尔河上游高地上，海拔1，754米。人口171.3万（1984）。始建于1886年，原是一个探矿站，以后随金矿的发现和开采迅速发展为城市。

Below a lot of circumstances, as a result of a variety of reasons this kind of ore does not have large-scale exploitation, because these ore contain prussiate but the copper of dissolve is mineral, reduce gold substantially thereby reclaim rate, raise the wastage of prussiate substantially, and the cost that raises follow-up processing.

在很多情况下，由于多种原因这类矿石并没有大规模开采，因为这些矿石含有氰化物可溶的铜矿物，从而大幅度降低金的回收率，大幅度提高氰化物的消耗量，以及增加后续处理的成本。

And has built the relations between pressure and pseud o-pressure,and the law distributed condensate oil content,when gas well is prod ucing from the reservoir.

利用凝析气藏等温衰竭过程中凝析油含量与随压力变化的数据确定出开采过程中储层内凝析油含量的分布特征。

The oil-field company, as a bright light of we Yanchang Petroleum, guides us to exploit dashing surges of crude oil; the oil refinery, being the heart of we Yanchang Petroleum, is vital to us just as it beats ceaselessly; The pipeline company, much similar to our blood vessel, infuses fresh blood everyday, then transmits oil and gas for us; the sales company, like our publicity agent, makes every possible effort, so much so that we can gain public praise and thus have a foothold in the petroleum market. Behind all these mainstays is our towering headquarters, which, so much as a brilliant lighthouse, instructs us to sail towards the bright future, making us iridescent forever.

油田公司是我们延长石油的一盏明灯，指引我们开采出汹涌澎湃的原油；炼化公司犹如我们延长石油的心脏，为我们生命的延续怦然跳动；管输公司如同我们延长石油的血脉、每天注入新鲜血液，把油气--这生命的源泉给我们传递；销售公司则是我们的宣传大使，为我们立足于石油市场，树立良好口碑不断打拼；而在这些中流砥柱的背后傲然屹立着我们的总公司，它犹如光芒四射的灯塔，指引着我们驶向光明的未来，让我们永远喷射着璀璨的光芒。

The High-Water-Content and Quick-Setting Materials are a new kind of cement with many unique properties: 1. high water content. 2. quick setting and strengthening. 3. long pumpability time. 4. good mechanical properties. 5. the property of re-developing strengthen after ultimate loading.

高水速凝材料是为适应煤炭开采技术的发展需要而研制出的一种新型固体胶结材料，它具有许多独特的优点：①水用量大；②速凝早强：③可泵时间长；④良好的塑性特性；⑤极限荷载后强度再发展性能。

The present environmental situation of radioactivity at the 90th Mine was monitored. The data showed that the envitonment in this mine had been radioactively pollutied.

通过对露天开采后的90号矿点放射性环境现状监测，数据表明，该矿点的环境已遭到放射性污染。

Mined nickel output rose 7% to 28,505 tons as the Raglan and Nickel Rim South mines in Canada and Xstrata's Australian mines recovered more metal.

开采镍产量同比增长7 ％至28505吨作为拉格兰和镍环南地雷在加拿大和Xstrata的澳大利亚矿山回收更多的金属。

And that rare metals mining exists uranium and thorium radioactive pollution.

而稀有多金属矿的开采可能带来铀和钍等放射性污染。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
