The electroformed copings and interfacial area were examined by SEM and EDS analysis. Results: Surface roughness increased by sandblasting, O content had not been greatly improved by preoxidation, the coping surface formed a porous structure after applying gold bonder. The gold and porcelain combined tightly, mechanical chimera and simple diffusion of Al, O elements were observed in interfacial area.

Oxidizing feature which is oxidizing leaching of every element, studied kinetics of anode oxidation, analyzed oxidizing slag with XRD and SEM during suspension electrolysis of zinc sulphide mine. The results show that zinc sulphide concentrate in different suspension electrolysis solution can be oxidized. However, the ore in zinc sulphide, ammiaonia sulfate and sulfuric acid suspension electrolysis solution can be oxidized obviously and has better oxidation rate.

确定了硫化锌矿悬浮电解时的电解液后，我们又对硫化锌矿在悬浮电解过程氧化特征即矿物氧化时其中各元素的氧化溶出情况进行分析，对阳极氧化进行了动力学研究，对氧化渣进行XRD和SEM分析，以了解其含锌矿物在悬浮电解过程中的氧化规律，还进行了渣中元素硫的回收。

For all the transition metals, the binding energy first increased and then decreased as the number of d electrons increased, and the strong attractive interactions of these atoms with sheet was due to the interaction of valence electrons in the 3d shell with 2p electrons of carbon.

过渡族元素随着外层d电子数的增加，其结合能先增加再降低，过渡族元素的3d电子与碳原子的2p电子的相互作用导致了与碳管的稳定吸附。
