石灰石

They used limestone of different quality and large-fluctuant-range waste stone in proportion and substituted a part of clay with clay stone to produce cement. And the physical performance of the produced Portland cement was improved greatly-28 d strength increased from 50.4MPa to 54.5MPa, and output of the rotary kiln increased. Moreover, the company also tried to use green shale as admixture to produce compound cement and successfully produced compound Portland cement with a little low early strength and a little higher 28d strength than slag Portland cement. And the cement cost decreased 19.59 yuan per ton.

将CaO含量波动范围较宽的废石与不同品位石灰石按比例搭配使用，将其粘土质特性的废石替代部分粘土生产；而且生产的硅酸盐水泥熟料物理性能有较大提高，28d强度由原来的50.4 MPa提高到54.5 MPa，窑产量也有一定的提高；此外，该公司还进行了将绿色页岩作混合材生产复合水泥的生产探索，成功生产出了早期强度略低，但28d强度略高于矿渣硅酸盐水泥的复合硅酸盐水泥，且使水泥生产成本降低19.59元/t。

They reckon it has always contained a lot of nitrogen, but that earlycarbon dioxide was mopped up by the formation of limestone while methane levelsrose as a result of the exhalations of a group of bugs—then common, nowrare—called methanogens.

他们估计大气层中已经有很多的氮素，而早期的二氧化碳是石灰石的形成释放出来的，与此同时，在当时极为普遍的产甲烷菌还源源不断的释放出甲烷气体。

It was formed as a limestone cave during the last iceage

它是在冰河时代末期形成的一个石灰石坑洞。

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。
