Our country ethylene diamine mainly uses in producing the agricultural chemicals (woods manganese zinc, dithane Z-78, generation of woods amine and pesticide, weed killer, disinfectant), the surface active agent (lives geminate stearic acid amide, alkyl imidazole lin, double amide, with oxirane, epoxypropane synthesizes non-ionic surface active agent), the epoxy resin firming agent (polyamide resins, epoxy firming agent, hydroxyethyl ethylene diamine and so on), the wash assistant (ethylene diamine four ethanoic acid and sodium salt series chelating agents), medicine raw material (aminophylline, washes must be peaceful, nose eye only, deinsectization spirit and so on), water treatment medicinal preparation (ethylene diamine four methylene phosphonates, second grade trunk base ethylidene two phosphine acids), corrosion inhibitor dye fixing agent, photography materialFixing bath and oil dope and so on.

我国乙二胺主要用于生产农药（森锰锌、代森锌、代森胺及杀虫剂、除草剂、杀菌剂），表面活性剂（生成双硬脂酸酰胺，烷基咪唑啉、双酰胺，与环氧乙烷，环氧丙烷合成非离子表面活性剂），环氧树脂固化剂（聚酰胺树脂，环氧固化剂，羟乙基乙二胺等），洗涤助剂（乙二胺四乙酸及其钠盐系列螯合剂），医药原料（氨茶碱，洗必泰，鼻眼净，灭虫灵等），水处理剂（乙二胺四甲叉膦酸盐，乙脒基乙叉二膦酸），缓蚀剂染料固色剂，照相材料定影液及润滑油添加剂等。

The results showed that the light stabilizer BHW1 by adding component chelating metal ion in HALS complex had better light stability and balanced performance than other HALS complex .

实验表明：引入金属离子螯合剂组成的复合光稳定体系BHW 1在农用聚烯烃棚膜中应用效果良好，具有更为均衡的光、热稳定性能；自然曝晒实验和大田实验证明复合受阻胺光稳定剂的光稳定性能优于单组份光稳定剂，光稳定剂复合化是聚烯烃防老化最有成效的解决方式之一。

In iron-deficient cells, photosynthetic pigments content decreased, efficiency of photosynthesis was low, With the increase of the concentration of the iron-chelator 2, 2'-Dipyridyl in media, Fv/Fm decreased, indicating photoinhibition increased, the results were consistent with previous research; Heterocyst induction had one delayed time dependent on the status of iron-deficiency, More severe of the iron-deficiency condition, more late of the heterocyst induction, It is possible that certain iron-related genes may directly regulate heterocyst development; under different iron limitation conditions, Protein pattern were different, more serious of the iron-deficiency conditions, less bands of the protein pattern, We could not find the iron-deficiency induced protein; In general the toxic effects of ROS were potentiated by excess iron, But our results revealed that even under iron-deficiency conditions, Oxidative damage existed.

铁限制的细胞光合色素含量下降，光合作用能力下降，随着铁螯合剂2，2'-dipyridyl浓度的增加，叶绿素荧光F〓／F〓逐渐降低，显示光抑制变强。与前人的研究结果相似；依赖铁缺失状态，异形胞诱导有一段推迟的时间，铁缺失越严重，诱导越迟，推断某些铁相关的基因会直接调节异形胞发育；在不同铁营养条件下，蛋白质图谱的变化趋势很明显，缺铁越严重，则蛋白质谱带数愈少，但本文未能找到特异诱导蛋白；一般认为铁过量情况下ROS产生加强，本文结果显示即便在铁缺失条件下，也有氧化胁迫伤害，而且缺铁越严重，活性氧伤害越大。

Up to now, there are many reports about complexes of hydrazone and monohydrazidate, while fewer is reported about bihydrazidate and its complexes.

另一方面，含有多个配位原子的N-取代水杨酰肼是一种强螯合剂，是制备多核配合物的理想配体。

Cement and silver sand are used as the basis materials for solidifying galvanized sludge containing heavy metals such as Ni,Cr and Cu,the lixivium test to solidified matter shows that the effect of solidifying galvanized sludge with cement is good.

采用水泥和细砂作固化基材处理含Ni、Cr、Cu等重金属的电镀污泥，对固化块的浸出试验表明：水泥固化该电镀污泥效果良好，固化过程中加入适当的螯合剂KS-3，可以提高固化效果，并对固化块在不同pH浸取剂下的重金属浸出浓度进行了研究。

Objective To investigate the effects of EDTA on the structure of mucoid Pseudomonas aeruginosa biofilm.

目的 探讨金属螯合剂依地酸钠对黏液型铜绿假单胞菌成熟生物膜的杀菌作用和对其结构的影响。

Of the few chelating agents tested, all were found to exert a marked inhibitory action on the reconstitution.

三从螯合剂对重组合的抑制作用可看出SD的铁在重组合中是有功用的。

The metal pollution reducing mechanism of different chelating agent was also analysized in this paper.

本论文还对不同螯合剂减少硅晶片表面金属铜污染的作用原理进行了理论分析。

As with other chelating agents, the patients' mineral status should be determined before administering DMPS and repletion of deficient minerals accomplished.

跟其他螯合剂一样，给DMPS前要先检验评估患者体内的矿物质的状况，如有不足要先补充。

1St, This product union and the optimal near ten years for the domestic feed enterprise, the breeding farm design's cattle and sheep feed formula, strengthened VA, VD, VE, the nicotine acid and the biological element specially and so on, and include the rich electrolyte, the trace element, the chelating agent, the seasoner, metabolism regulation medicinal preparation, the nutrition comprehensive and are balanced, may adjust the milk cattle and sheep microcycle, maximum limit enhance cow's dry material amount of radiation, display cow's heredity potential fully, enhance the milk production quantity, the extension milk production peak.
