The conversion film is probably constituted of amorphous and pored alloying tannate chelate.

这种转化膜很可能是由有一定孔隙的非晶态单宁酸膜层构成.

In this paper, the new chelating resin (PSIM) with a polythioether backbone bearing imidazole group is first synthesized by the reaction between polychloromethylthiirane and imidazole.

通过聚环硫氯丙烷与咪唑进行高分子，成了以聚硫醚为主链、侧链带有咪唑基团的螯树脂（简称PSIM）。

According to the problems in dyes production,the role of cupric ion in coupling-cupric complexation was discussed,and the chelated forms of formazane reactive dyes were introduced.

并结生产和用中的实际问题,对偶-铜络一步完成中铜盐的作用、甲铜络物的啮形式及其性能等研究成果进行了介绍。

3, A chelating agent which forms an easily water-soluble metal chelated compound such as nitrilotriacetate (NTA) or ethylene diamine tetraacetate (EDTA) is incorporated in a detergent composition.

在洗衣粉中掺入螯剂，例如次氮基三乙酸酯（NTA）或者是乙二胺四乙酸酯（EDTA），这些螯剂易于形成水溶性的属螯物。
