查询词典 tridentate

When the concentration of zinc nitrite is lower than 0.1 M,(002) is the prior face for zinc oxide. As the concentration raise, the other kinds of crystal face would appear. Among those data,(002) grows the best when the concentration of zinc nitrite is 0.06 M. We add lactic acid and citric acid respectively; there is an carboxyl group on the lactic acid and three carboxyl groups on the citric acid. The monodentate of lactic acid helps the growth of zinc oxide, compared to the tridentate of citric acid which can only produce zinc oxide film under very low concentration, but the growth of (002) face is not that stable as adding the lactic acid and zinc will electrodeposit to substrate.

实验中，当硝酸锌浓度低於0.1 M 时，氧化锌以(002)面为优选位相，当浓度提高，其他晶面将会出现，当硝酸锌为0.06 M，(002)晶面成长最佳，分别加入乳酸和柠檬酸，乳酸结构上有一羧基团而柠檬酸有三个羧基团，单芽基的乳酸有助於氧化锌成长，对照於三芽基的柠檬酸，则必须在极低的浓度下才能制备氧化锌薄膜，但(002)面成长却没有添加乳酸来的稳定而金属锌也会电沉积到基板上。

In this sense, IDA plays dual effects, tridentate chelating to Cu(2) and bridgebetween two Cu(1) andCu(2).3 Metal complexes were selected as the appropriate for the study of cleavage plasmid pBR322DNA by gel electrophoresis technique. The results showed Ni and Mn complexes could cleave effect- ively DNA in the presence of H2O2 at physiological pH and temperature, whereas individual Zn complex could cleave effectively DNA.

通过电泳实验研究了一系列金属配合物与pBR322DNA的作用，发现在Tris-HCl缓冲溶液中，生理条件下，镍、锰配合物在共反应物H_2O_2存在下能够很好的断裂DNA，而Zn配合物单独作用就能够使DNA由ccc型转化为oc和linear型。
