方解石

They crystallized in veins that are several centimeters in diameter, which were made up mainly of calcite, sodium feldspar albite, and iron sulfite pyrite.

它们体现在那些静脉直径几厘米，其中大部分为方解石，钠长石钠长石，黄铁矿和铁的亚硫酸盐。

XZM Ultrafine mill is a machine for producing fineness and ultra-powder. It is mainly used for grinding the materials whose hardness is middle and low, moisture below 6%, and Moths hardness should be blow 9 grade and non-explosion and non-flammability, such as: calcite, chalk, limestone, dolomite, kaolin, bentonite, steatite, mica, magnesite, illite, pyrophillite, vermiculite, meerschaum, attapulgite, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate ore, potassium ore pumice, etc.

XZM 中速微粉磨是一种细粉及超细粉的加工设备，它主要适用于中、低硬度物料的研磨粉碎，如高岭土、石灰石、方解石、滑石、大理石、重晶石、石膏、白垩、白云石、膨润土、云母、菱镁矿、伊利石、叶腊石、蛭石、海泡石、凹凸棒石、累托石、硅藻土、石墨、明矾石、萤石、磷矿石、钾矿石、浮石等湿度小于6％，莫氏硬度在9级以下非易燃易爆的非金属物料。

The content of anhydrite and calcite is lower. The content of anhydrite will increase with the addition of flux CA while the content of calcite will decrease.

煤中添加助熔剂CA后，煤灰中硬石膏含量增加，并且随着助熔剂CA量的不断增加，方解石含量在不断减少，硬石膏含量在不断增加。

The paragenetic sequence are in the order of calcite-kaolinite, secondary quartz overgrowths-illite-dawsonite and ankerite.

成岩共生序列依次为方解石-自生高岭石、次生加大石英-伊利石-片钠铝石、铁白云石。

The carbonate cements, mainly consisting of ferroan calcite and ankerite, are telogenetic cements.

这样形成的碳酸盐胶结物为晚期胶结物，主要为含铁方解石和铁白云石。

The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。

The distribution law of calcite and whewellite affirms again that Weertman's water-film theory under ice is correct and indicates that the water-film on the stoss and the top-surface prevails.

同时也说明方解石的沉淀过程，不仅仅是背冰面的复冰过程。方解石的分解与沉淀与水膜承压而溶有较多的CO〓有关。

A soft, pure, earthy, fine-textured, usually white to light gray or buff limestone of marine origin, consisting almost wholly (90-99%) of calcite, formed mainly by shallowwater accumulation of calcareous tests of floating microorganisms and of comminuted remains of calcareous algae (such as cocoliths and rhabdoliths), set in a structureless matrix of very finely crystalline calcite.

中文解释=海产起源的石灰石，柔软、纯净、土质、组织精细，通常从白色到浅灰或浅黄色，几乎完全（90-99％）由方解石组成，主要由浮游微生物的粉碎残留物浅水堆积而成，嵌在非常精细的方解石晶体的无定形填质中。

That is to say, less and less of the sea will remain hospitable for calcifying organisms.

在早年的研究中，许多科学家判断，海洋酸化问题不大，因为至少对方解石而言，表层水仍然保持过饱和，而方解石是最坚硬的一种碳酸钙。1990年代，迈阿密大学的海洋生物学家兰敦进行了一项精妙的实验，来验证科学家的猜测。

The depressing ability of the macromolecule organic depressants can be improved by the increase of their D.S.. The high D.S. CPVA and CPEG show strong depressing ability to calcite, while CPEG indicates strong depressing ability to diaspore, and HPAM to pyrite.The depressing mechanism of organic depressants was confirmed by the measurements of zeta potential, contact angles, adsorption capacity and IR spectrum.

利用动电位、接触角、吸附量和红外光谱等测试方法和手段，探讨了抑制剂的作用机理：苯氧乙酸类小分子抑制剂与方解石之间可发生较强的化学作用，可以选择性地吸附在方解石表面，使捕收剂发生解吸或阻止捕收剂在矿物表面的吸附而使矿物受到抑制；大分子抑制剂则主要是依靠亲固基吸附在矿物表面，再利用其长链的强亲水性而使矿物受到抑制。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
