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。

It was proved by IR spectroscopy that Zn2+ and hydrolyzed ion were chelated with polysilicic acid to produce the polymer of zinc-silicon. The reaction was not the simple physical blending,but the chemical reaction forming the inorganic polymer with special structure.

红外光谱证实了PZSS中Zn2+及水解Zn2+离子可与共存的聚硅酸起螯合反应生成锌硅聚合物，聚硅酸与Zn2+反应并不是单纯的物理混合加成作用，而是形成了具有特殊结构的无机高分子的化学反应，这种新型絮凝剂所具有的优良絮凝特性是由各物质间以化学作用为主的物理化学因素共同作用的结果。

It was proved by IR spectroscopy that Zn(superscript 2+) and hydrolyzed ion were chelated with polysilicic acid to produce the polymer of zinc-silicon. The reaction was not the simple physical blending, but the chemical reaction forming the inorganic polymer with special structure. The better flocculating efficiency was resulted mainly from the chemical and physico-chemical factors among the components.

红外光谱证实了PZSS中Zn(上标 2+)及水解Zn(上标 2+)离子可与共存的聚硅酸起螯合反应生成锌硅聚合物，聚硅酸与Zn(上标 2+)反应并不是单纯的物理混合加成作用，而是形成了具有特殊结构的无机高分子的化学反应，这种新型絮凝剂所具有的优良絮凝特性是由各物质间以化学作用为主的物理化学因素共同作用的结果。

The ability of acne treatment was performed by inhibition of Propionibacterium acne and Staphylococcus epidermidis, which commonly isolated from pustular acne lesions.

结果发现乳清、肽类、醣类、菌之胞内萃取物均对铜离子产生螯合能力，显示克弗尔具有明显之抗氧化活性。

Other types of titanate are chelate (for greater stability in wet environments), quat (water-soluble systems), coordinate and cycloheteroatom.

其它类型的钛酸酯是螯合型、水溶型、配位型和杂环原子型。

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。

The scFv formed inclusion body in E. Coli. 8 mol/L urea was used to solubilize the inclusion body, and the scFv was then purified in two steps , including Ni 2+ chelating affinity chromatography and gel filtration.

大肠杆菌表达的单链抗体包涵体，用8 mol/L尿素裂解，经过Ni离子螯合亲和层析和凝胶过滤两步纯化后，纯度达到97%以上，再通过透析复性除去尿素。

Three hundred one-day-old avian broiler whose body weights were near consistent and healthy were selected, and were divided into 5 disposes randomly, 3 repeats in each dispose. Adopting single factor to compare the effect of complex amino acid trace element chelated on production performance, death rate and disease occur rate in leg of broiler when it was added with high Cu (Cu 250 mg/kg) level, 1 times NRC level, 0. 5 times NRC level, 0 level (neither use chelated nor sulphated) and 1 times NRC level as sulphate.

选体重近似一致、健康的1日龄艾维茵肉用仔鸡300只，随机分为5个处理，每个处理3个重复，采用单因子设计比较研究了复合氨基酸螯合微量元素(Fe、Cu、Mn、Zn)高铜水平(Cu 250 mg／kg)、NRC水平、0.5倍NRC水平、0水平和硫酸盐对肉用仔鸡生产性能、腿病发生率和死亡率的影响。

The enrichment coefficient and translocation factor both reached 1 of Tagetes erecta L with Cd and Tagetes patula with Pb, which indicated that Tagetes erecta L and Tagetes patula could be used for the remediation of contaminated soil.

施加EDTA后万寿菊对Cd和孔雀草对Pb的富集系数和转移系数均达到了1以上，这表明这两种植物可用于螯合辅助植物提取方式的污染土壤修复。

Structural analysis reveals that the assemblies of these complexes are mainly directed by counter anions, followed with the change of anions from simple inorganic species (SCN~-/dca/Cl~-) to organic ones (ip/nip/tp/chdc), diversiform structures are formed varying from mononuclear, tetranuclear molecules to infinite 1-D and 2-D frameworks.

第三章利用4-bpt的同分异构体4-氨基-3，5-双(2-吡啶基)-1，2，4-三唑(2-bpt)作为螯合试剂，与多种无机/有机阴离子以及金属Cd~盐反应，得到了一系列Cd~配位化合物(7-15)。

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。
