螯

The effect of the molar ratio of amino acid to copper,microwave power,reaction time and pH value on chelate reaction was investigated.

采用微波螯合工艺，对复合氨基酸与铜的配位比、微波时间、微波功率及反应体系的pH对螯合反应的影响进行详细的研究。

The chelate structure was examined by AFM scaning, single strand structure at AFM gram is Ala-Gln, two combined single strand is Ala-Gln-Zn~(2+), and atomic radius of Ala-Gln-Zn~(2+)'s conjunctive atom is about 0.24 to 0.25nm, which is near to Zn~(2+), so the conjunction atom is Zn~(2+). Thus the coordination reaction and the molar ratio 2:1 is proved again.

原子力显微扫描指出，大量出现的单一弯曲链状结构是Ala-Gln分子，而两两组合连接的链状结构，则是Ala-Gln-Zn~(2+)螯合物，且连接两个链状结构、半径约为0.25nm的中心原子是Zn~(2+)，证明Ala-Gln与Zn~(2+)形成配位比为2：1稳定螯合物。

The thesis also introduced the procedure of chelate reation with the raw material of aspartame and zinc nitrate、bluestone and autunite nitrate.

The thesis investigated the effect of reation temperation, pH value, and material ratio on the chelating reation. To determine the L-aspartic acid zinc complex\' chelation ratio by orthogonal experiment, we get the best conditions of reaction. On this basis, the thesis synthesized L-aspartic acid autunite complex and L-aspartic acid coppe complex.

本课题探讨了反应温度、反应溶液的酸度、原料配比n：n三个方面对L-天门冬氨基酸与金属元素反应得影响，并以螯合率为指标，运用L_9(3~4)正交设计实验对影响L-天门冬氨基酸螯合锌的条件进行了研究，得出最佳的反应条件。

In this experiment, we utilized organic solvent ethanol, acetone sedimentation separation method to separate and purify metal chelates. In the mean time, the chelation ratio of L-aspartic acid/aspartame zinc、autunite、coppe、ferrous complex was determined by EDTA complexometric titration and the products\' structure were analyzed and confirmed by IR spectrometry.

本试验采用有机溶剂乙醇、丙酮沉淀分离法来分离提纯金属螯合物，借助EDTA络合滴定法测定了L-天门冬氨基酸、阿斯巴甜与金属元素钙、铁、铜、锌的螯合率，利用红外光谱对产品结构进行了分析确认。

The optimum conditions were evaluated basing on the chelation rate and yield of amino acid chelates.

正交试验表明，螯合的最佳工艺为：反应体系pH为11，微波功率为342W，螯合时间为6min，氨基酸与硫酸铜配位比为2：1。

The feeding frequency of male crabs in unit time (30 seconds) is lower than that of the females because each male has only one minor cheliped for feeding.

摄食乃招潮蟹最常见的行为，她们利用小螯夹取表面土摄食其中的有机养分，而雄蟹只有一只小螯取食，其在单位时间内的进食次数比雌蟹少，此外，愈小的个体，吃得愈快。

And the complex of hydroxyquino line and metal iron is a small molecule luminous material which has very high luminescence efficiency.
