And the mechanism of ATRP is discussed from the view of complex-catalytic reaction. It is deduced that the active center in ATRP is not pure radical but complex active center, which maybe a complex with radical and complex ion. The structure of active center may have a "bridge"structure formed through propaganating radical and transition metal ion, and the active center exists in a"cage"generated by ligand-transition metal ion-organic halide and monomer or solvent.

论文运用基团贡献理论对一些实验现象和结果进行了讨论和分析，并结合研究结果对络合催化引发原子转移自由基聚合反应的机理进行了初步的探讨，认为：过渡金属化合物与有机配体参与的络合催化引发原子转移自由基聚合反应中，聚合反应的活性中心不是纯粹的自由基活性中心，而是与过渡金属相结合的、有着某种"笼"结构存在的复合式活性中心，同时该活性中心以自由基特性为主，同时兼具某种程度的其它活性中心特征（如阳离子和络合聚合活性中心）。

Of the calcium inside the human body, the physiology function of the calcium ion, the human body is to the absorption of the calcium ion, supersession, regulation mechanism to calcium ion etc. aspect to write.

At the same time, it is tersely described the ion molecule reactions in thedrift tube and the interactions between the ion and neutral gas molecules during ion drift process.

同时，为更好的理解IMS内部的反应机理，简要介绍了迁移管内分子离子的化学反应过程以及离子在迁移过程中和分子的相互作用。

It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理，氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱，而对含铁硅酸盐钠辉石强烈抑制，从而扩大了两者之间的浮选差异；SiF〓是矿浆中起抑制作用的主要成分，SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物，而且还与Si-O键形成稳定的Si-F共价键，而与赤铁矿表面只能形成离子型配合物，根据晶体配位场理论，与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用，因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用，却能够选择性地抑制钠辉石的上浮。
