After saturating the aqueous layer with anhydrous potassium carbonate, the organic layer was removed and the aqueous layer was extracted with tetrahydrofuran 4 .times.

饱和后，水层无水碳酸钾，有机层被拆掉，水层提取四氢呋喃

In the process of all the world generally often can make use of the craft stone carbonate rocks (including some of argillaceous impurity), whether they are after heavy crystallization and metamorphism, called the marble.

在工艺界往往笼统地把所有可作工艺石料利用的碳酸质岩（包括一些含大量泥质等杂质的），不论其是否经过重结晶和变质，均称为大理石。

Mr Bloomberg has suggested a slightly different tax, involving a direct levy on drink producers, and has astutely highlighted its financial benefits at a time when the state faces a multi-billion dollar budget shortfall.

在金融危机令美国各州政府财政吃紧的形势下，关于对含糖饮料尤其是碳酸饮料征税的呼声越来越高。去年，纽约州长戴维·派特森也曾提议对含糖饮料征收所谓的"肥胖税"，但是由于公众的反对而作罢。

In the end, the extractive distillation method was applied to separate and purify the binary azeotrope mixture, methanol-dimethyl carbonate. The isoamyl acetate was used as extractant and the two tower system was introduced to continuous extractive distillation operation. The results show a better separation effect.

最后采用萃取精馏的方法，对甲醇-碳酸二甲酯的二元共沸混合物进行了分离提纯研究，以毒性较低的乙酸异戊酯为萃取剂，采用两塔连续萃取精馏操作，结果表明，分离效果比较理想。

So geochemist Robert Hazen of the Carnegie Institution of Washington in Washington, D.C., and colleagues traced the origins of nearly 3000 common terrestrial minerals--such as turquoise, azurite, and malachite--to about a dozen ancient minerals.

因此，华盛顿特区华盛顿卡内基研究所的地球化学家Robert Hazen和他的同事们，对近3000种常见的地球矿物质――例如绿松石、蓝铜矿、碱式碳酸铜――进行追本逐源，发现它们源于十几种古代的矿物质。

He found that the red pigment proved to be iron oxide, hematite; a yellow consisted of clay containing iron or yellow ochre; a blue color was a finely powdered glass; and a pale blue was a copper carbonate, probably azurite; green were malachite; black was charcoal or boneblack; gray, a limestone mixed with charcoal; and a quantity of pigment remaining in a paint pot used in the decoration, contained a mixture of hematite with limestone and clay.

他发现红颜料是铁的氧化物赤铁矿；黄色颜料由含有铁或黄赭色粘土组成；蓝颜色为细微的玻璃粉；而普蓝就是碳酸铜，或许是蓝铜矿；绿颜料为孔雀石；黑色为木炭或骨黑；灰色，石灰石混合木炭而成；而一些颜料残留在用于彩绘装饰的颜料瓶里，含有赤铁矿与石灰石及粘土的混合物。

In separate bowl, combine flour, baking powder, baking soda, and salt.

在另外的一个碗中，将面粉，发酵粉，碳酸氢纳发酵粉和盐混合。

Recent research advance in preparation of ultrafine barium carbonate and strontium carbonate is summarized.

综述了超细碳酸钡和碳酸锶制备方面的研究进展。

It won't be like carbonated drinks and would be devoid of any toxins.

它不像碳酸饮料，而且不含任何毒素。

It is one of most effective and safe manipulation of gastric bezoar with injection of 5% Sodium Bicarbonate solution, combination with the forceps and snare.

电子胃镜不仅是诊断胃石最直接的方法，而且胃镜下行胃石内注射碳酸氢钠联合圈套器勒扎碎石，方法简便，安全，费用低，治疗效果好。
