石灰石

With quartz sand, limestone, dolomite, glass as the main raw materials, including glass, approximately 90%.

以石英砂、石灰石、白云石，玻璃等为主要原料，其中玻璃约占90%以上。

The effects of this limestone flour on concrete are seldom realized and little approach is finished. The settlements of these problems will bring good economic and environmental benefits. This paper researched the effacement and improvement of limestone flour as concrete admixtures on workability, mechanical property durability , dry-shinkage and creep of concrete.

另外由于石灰石碎石和机制砂在生产过程中夹杂一定量的石灰石粉，这些石粉在混凝土中所起的作用，人们对它的认识和研究还是很少。

The second set consisted of patina ― a chemical film encrustation on one of the limestone boxes.

第二套样本中包含有铜绿――在一个石灰石盒子上附着的一种化学物质。

Finally, the paper concludes the adoptions of this process is feasible, gives somesuggestion for concrete execration of FGD engineering.

论文最后得出了该工程采用石灰石-石膏法工艺可行的结论，并分析了工程实施中的关键问题。

In addition, the territory of granite, potash feldspar, limestone, gold, silver and copper are also rich.

此外，境内花岗岩、钾长石、石灰石、金、银、铜等也比较丰富。

In order to improve sintering raw mix size composition, increasing sinter TFe content and reducing solid fuel consumption,the industrial sintering test with all burnt lime to replace the limestone in BaoGang Iron Making Plant was conducted, and anticipative effect was gaine

为了改善烧结混合料的粒度组成、提高烧结矿TFe含量、降低固体燃耗，包钢炼铁厂进行了用全生石灰取代石灰石的工业试验。本文介绍了湘钢二烧使用生石灰的情况以及生石灰配消系统的改造情况，并提出了进一步完善的措

Proven metal and non-metallic mineral deposits are copper, lead, zinc, gold, silver, manganese and limestone, quartz, feldspar, Glauber's salt, zeolite, more than 30 kinds of stone, and so on.

已探明的金属和非金属矿藏有铜、铅、锌、金、银、锰和石灰石、石英石、长石、芒硝、沸石、麦饭石等30多种。

Third,? Proven exploitable reserves of mineral deposits, only 6,000,000 tons of Glauber's salt, 100,000,000 tons of limestone annual emission of 70,000 tons of quality natural mineral water. Fourth, very difficult to finance.

其三，？已探明可开采的矿藏只有藏量600万吨的芒硝、1亿吨的石灰石、年涌出量7万吨的优质天然矿泉水。

Minerals found in the region has 31 major categories, representing the province's mineral resources have been found in 23% and found that more than 160 types of mineral point, the proved reserves of 15 kinds of minerals, of which: ilmenite, graphite ore are domestic large mineral reserves of 6,000,000 tons and 4,000,000 tons or more; limestone, gypsum, Glauber's salt, granite and coal and other non-metallic fuel and energy resources in the northwest edge itself, which proved coal reserves of 1.068 billion tons, oil-page rock 248 million tons, 7.73 million tons of Glauber's salt, 1.17 billion tons of limestone, gypsum 140 million tons, due to a low degree of geological exploration, the comprehensive development of a low utilization rate, at present the development and utilization of mineral ores accounted for only 30% of the region, cooperating with the outside great potential for development.

全区已发现矿产9大类31种，约占全省已发现矿产的23%，发现各类矿产点160余处，探明储量的矿种15种，其中：钛铁矿、石墨矿属国内特大型矿产，储量分别为600万吨和400万吨以上；石灰石、石膏、芒硝、花岗岩和煤炭等非金属和能源燃料类资源在西北占居优势，其中煤炭探明储量10.68亿吨、油页岩2.48亿吨、芒硝773万吨、石灰岩11.7亿吨、石膏1.4亿吨，由于地质勘探程度低，综合开发利用率低，目前开发利用的矿种仅占全区矿种的30%，对外合作开发潜力巨大。

Sculptors have generally sought to produce works of art that are as permanent as possible, working in durable and frequently expensive materials such as bronze and stone: marble, limestone, porphyry, and granite.

为了让自己的作品经得住时间的考验，雕刻家们利用耐久却相对昂贵的材料，譬如青铜，或大理石、石灰石、斑岩和花岗岩，更甚者以玉、象牙、金，银浇铸雕塑。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
