在微型柱的填充材料中高分子螯合树脂由于高分子效应又增添了许多新的功能，具有合成简便、价格低廉、吸附容量大、干扰少和稳定性好与金属离子的结合能力强等优点因而适用于从环境样品中选择性地富集痕量重金属离子。

From the point of ion exchange and chelating ,the high adsorption selectivity was investigated by the peculary structure of amidoxime fiber(combined with crosslinking structure and the maximal conversion of cyano) and Au ion.

从离子交换和螯合吸附的角度，根据偕胺肟基纤维本身的交联结构和最大氰基转化特点以及金离子本身的结构特点对其高选择吸附性能进行了解析。

Chelate fiber with amidoxime group,which is obtained from chemical modification of PAN fiber,is treated with mercury nitrate to prepare anion-exchange fiber.The optimum conditions of the anion-exchange fiber absorption of the thiocyanate ion,such as ion concentration,time,the pH value were studied.

以聚丙烯腈纤维进行NH2OH化学改性制得的含有偕胺肟基的螯合纤维为原料，经Hg(NO3)2化学处理，制得阴离子交换纤维；并以硫氰酸根离子为研究对象，系统地探讨和研究了阴离子交换纤维吸附硫氰酸根离子的最佳条件参数：离子浓度、时间、pH值等。

In the presence of suitable nickel catalyst and without the chelation effect of special designed dithioacetals, simple aliphatic dithioacetals could react with a series of Grignard reagents to give the corresponding olefinic products.

因此在适当的镍触媒存在下，脂肪族硫缩醛在不需要特别的螯合作用下，即可以与一系列的格林那试剂进行烯化反应。

The coprecipitation is based on the formation of water-insoluble inner complex compounds of the trace elements with-SH group-containing reagent and the formation of disulphide directly in the solution owing to the easy oxidizability of the-SH group. During the formation of the solid disulphide phase the trace elements are coprecipitated.

痕量元素和含-SH基团的试剂形成不溶於水的螯合物，由於-SH基团易被氧化从而直接在溶液中形成固相二硫化物，同时将溶液中的痕量元素共沉淀下来。

The trace of red O phenanthroline Fe indicates: Fe 2+ was absorbed by roots and transported to stem, main vein of leaves when iron fertilizer was root inserted.

整根对铁的吸收已有较多的研究，铁可以Fe2 +、Fe3+或铁的螯合物形式被植物吸收。

The lyophilization treatment of silkie fowl blood meal and the hot-air drying treatment of broiler blood meal had the strongest inhibition in lipid peroxidation. All the blood meal showed higher ability of the ferrous ion chelating.

而所有的血粉样品其螯合亚铁离子能力都达到90%以上，彼此间无显著差异，血粉样品的抑制脂质过氧化能力以乌骨鸡冷冻乾燥的血粉效果最佳(p.05)且与自肉鸡热风乾燥之血粉无显著差异。

Committed to delivering ever better chelated products and services, Continually seek ways to exceed expectations, be efficient, effective and systematic in our approach.

承诺提供最好的螯合物产品和服务，不断寻求超过客户预期的高效，系统的产品和市场方案！

It is shown from study results that the soluble iron has a strong controlling effect on the phytoplanktonic growth, and most of soluble iron is chelated with ligand such as siderophore with high affinity to Fe 3+.

研究表明，可溶性铁对浮游植物生长有很强的控制作用，大部分可溶性铁是同具有极强铁亲和力的配位体螯合在一起的，如铁载体。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
