石灰石

A method for the determination of mixedness degree of red mud and limestone by spectrophotometry with 1,10-phenanthroline was developed. The mixture of red mud and limestone was dissolved by hydrochloric acid, and iron content in the sample solution was determined by spectrophotometry with 1,10-phenanthroline.

用盐酸提取赤泥和石灰石的混合料后，通过邻二氮菲分光光度法测定提取液中铁含量，进而求得混合料中氧化铁的质量分数，以此来衡量混匀度。

The monumental face pack consists of multani mitti, or fuller's earth, a lime-rich clay found across northern India and used in many face masks and body treatments.

这种特制&面膜&的主要成分是&漂白土&。漂白土产于印度北部，是一种富含石灰石的粘土，很多面膜和印度草药护肤品中都含有这种成分。

A soft limestone either pure or nummulitic was used for the bulk of the core blocks and a hard white limestone for the mantle.

软石灰石或nummulitic要么是纯为核心区块的大部分，是一个勤劳的地幔白色石灰岩使用。

Three kinds of typical shells, such as scallop, whelk, bloody clam, as well as one kind of limestone were chosen to perform desulfurization and calcination experiments on the fluidized bed platform.The microstructures of the tested samples were mensurated by means of one mercury porosimeter.

在流化床上对3种典型贝壳---扇贝、海螺、毛蚶以及一种石灰石进行煅烧脱硫试验研究，并利用压汞仪测定试验样品的微观孔隙结构，通过最可几孔径、孔隙率、比表面积等3个结构特征参数对微观结构进行定量分析；另外，还对试验样品的化学成分进行了分析。

It's in the mountains above Verona that the red limestone is quarried.

红色的石灰石是在维罗纳城边的山上开采出来的。

They were built mainly of limestone quarried on the Giza plateau itself.

他们建成的主要开采石灰石本身吉萨高原上。

They date back to Roman times, when limestone was quarried to begin building the Paris we know.

这得回溯到罗马时代，那时候石灰石被开采出来开始建造我们现在所知道的巴黎。

Eg.It's in the mountains above Verona that the red limestone is quarried.

红色的石灰石是在为罗纳城边的山上开采出来的。

The area is being quarried for limestone .

这地方正在开采石灰石。。。

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.

交际能力和语法的关系应该是目标与途径的关系。
