Compound 6 is a three-dimensional structure consisted of the independent uncharge components , and HO via hydrogen bonds linking together.

合成了超分子化合物［Mn〓〓〓〓］〓［Mn〓〓］〓2H〓O6和［Cd〓〓］7（C〓H〓O〓＝反丁烯二酸根），测定了它们的晶体结构。

Shellfish and many calcifying organisms play a crucial role in converting bicarbonate back to carbonate.

研究以贝类为对象，它们在海洋碳循环中负责将氢碳酸根转回碳酸根，然后以碳酸钙方式储存。

A fully automated simultaneous determination of nitrate and nitrite in water samples by sequential injection analysis based on the Griess diazo-coupling reaction and the formed azo dye for nitrite at 540nm and reduction to nitrite using coppered cadmium column.

用顺序注射分光光度法，通过一次进样。同时测定硝酸根和亚硝酸根。亚硝酸根是根据格里斯重氮－偶联反应，形成偶氮染料后在波长540nm下进行检测。而硝酸根则通过镀铜镉粒还原柱还原为亚硝酸根后进行测定。

But when hexacyanoferratedecomposes or hydrolyzes to release free CN-, it forms a lethal poison.

但当六氰合铁酸根分解或水解时，会释放出游离态的CN-，它有剧毒。

But when hexacyanoferrate decomposes or hydrolyzes to release free CN-, it forms a lethal poison.

但当六氰合铁酸根分解或水解时，会释放出游离态的CN-，它有剧毒。

In the second chapter, twelve compounds constructed by arenedisulfonates and metal ions such as alkali, alkaline earth and transition metal ions have been synthesized and structurally characterized.

第二章描述了在水溶液条件下芳烃二磺酸根离子与碱金属离子、碱土金属离子和过渡金属离子形成的十二个化合物的结构。

The thermodynamic calculation results indicated that the formation of calcium aluminate hydrate from aluminate solution with CaO is easier than that with Ca2, and the value of αk is great at low temperature; the temperature rise leads to the reduction of stability of calcium aluminate hydrate in the aluminate solution, and it can be decomposed at high temperature, which can both substitute for Ca2 and recover alumina in the process of Bayer.

热力学计算结果表明，氧化钙较氢氧化钙更容易使铝酸钠溶液中的铝酸根离子转化为水合铝酸钙，使铝酸钠溶液的平衡苛性比能达到很高的值；水合铝酸钙随着温度的升高，稳定性降低，因而能在拜尔法高温溶出过程中分解以代替石灰，并回收其中的氧化铝。

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。
