本论文采用常规的溶液合成方法，首先设计合成了一个以含有二硫缩烯酮结构的丙二酸类配体和过渡金属铁离子的单核配合物，再以此单核配合物作为配体设计合成了三个异多核配合物和配位聚合物。

The patients with methylmalonic acidemia and homocystinuria should be mainly treated with vitamin B12, betaine and L-carnitine, while the patients with isolated methymalonic acidemia should be treated with protein restriction, the special milk formula without isoleucine, valine, methionine, and threonine, and be given L-carnitine.

对伴有同型半胱氨酸血症患儿，治疗以维生素B12、甜菜碱和左旋肉碱为主；对不伴有同型半胱氨酸血症患儿以限制天然蛋白质摄入，给予去除异亮氨酸、缬氨酸、甲硫氨酸和苏氨酸的特殊奶粉及左旋肉碱治疗为主。

In terms of physical-chemical conditions of ore deposits and nano-theories and nano-effects, in connection with themodynamics discussion on Au migrational mode, this paper first time points out that Au is migrated chiefly in the form of nano-particle natural gold in ore-bearing fluid.

3根据金成矿的物理化学条件计算，引进纳米理论和纳米效应，联系Au迁移形式的热力学讨论，首次提出本区金矿成矿流体中Au主要以纳米微粒自然金形式迁移，但在地壳中的物理化学条件下可能部分呈金-硅配合物和金-硫配合物形式在一定范围内迁移

Most of characterized conotoxins are mainly from fish-hunting conus as well as several molluscivorous species, because they were believed to be toxic to vertebrateIn this study, we investigated the venom of Conus marmoreus and Conus vexllium from South China Sea by separating, purifying and protein sequencing technologies to character unknown conotoxins.

本文通过天然毒素的提取，分离纯化，蛋白质测序，化学合成与二硫键定位等手段对中国南海的食螺的大理石芋螺和食虫的菖蒲芋螺进行了新型小肽毒素的发现和鉴定研究。

O-MNT、 p-MNT and m-MNT are got by mononitrating toluene, and the quantity of p-MNT and m-MNT that are needed is increased greatly, there is a great economic benefit to improve their ratioes , so the objective of this study is to improve the ratioes of p-MNT and m-MNT in the mononitration of toluene respectively through changing temperature and mixed acid composition in industrial way.

甲苯一硝化生成邻硝基甲苯、对硝基甲苯、间硝基甲苯，其中对硝基甲苯和间硝基甲苯的用量明显增加，提高它们在产物中比例的研究，具有十分可观的经济价值，所以本文从工业化的角度出发，通过改变温度和硝硫混酸的组成，分别对提高一硝基甲苯中对、间位异构体的比例进行研究。

The hydrophobic and hydrophilic organic fractions each accounted for about 50% of DOC of the secondary effluent samples. Hydrophobic acids were the largest group accounting for 42%, followed by hydrophilic acids and non-acid hydrophilic matters at 26% and 24%, respectively; nonacid hydrophobic matters at 8% were the smallest group.
