二价羧酸

The most commonly used method for the covalent binding of biomolecules onto 1-D nanostructures is through the diimide-activated amidation of carboxylic acid terminated nanostructures.

最常用的方法是通过端羧酸基纳米结构的二酰亚胺活化氨基化合物来进行生物分子与1-D纳米结构的共价结合。

The three tetranuclear copper complexes are structurally analogous and they all consist of a pair of [Cu22]+ or [Cu22]+ fragments bridged by a deprotonated dicarboxylate into dumbbell-shaped, neutral, tetranuclear molecules.

三个四核混合价铜化合物具有相似的分子结构，它们由一对[Cu22]+或 [Cu22]+碎片和一个架桥的二羧酸配体组成中性的四核的哑铃型结构。

The amount of Na(superscript +), NH4(superscript +), K(superscript +), Mg(superscript 2+), Ca(superscript 2+), Zn(superscript 2+) in fruits and juice (sports water, green tea , pear juice, carrot juice and carrot and orange juice) were respectively separated and detected by non-suppressed ion chromatography. And pyridine-2, 6-dicarbexylic was used as mobile phase to separated monovalent cations and pyridine-2, 6-dicarbexylic-ethylenedi-amine-oxalic acid was used as mobile phase to separated divalent cations.

采用非抑制型离子色谱法测定了水果以及饮料（运动型饮料、绿茶、水蜜桃汁、胡萝卜汁和胡萝卜橙汁）中Na、NH4、K、Mg(上标 2+)、Ca(上标 2+)、Zn(上标 2+)的含量，其中一价阳离子以吡啶－2，6-二羧酸为淋洗液测定，二价阳离子以吡啶－2，6-二羧酸+乙二胺+草酸为淋洗液测定。

The amount of Na+, NH4+, K+, Mg2+, Ca2+, Zn2+ in fruits and juice (sports water, green tea , pear juice, carrot juice and carrot and orange juice) were respectively separated and detected by non-suppressed ion chromatography.

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
