机械镀锌的形层过程既没有热镀锌那样的高温冶金反应，也没有电镀锌那样的电沉积效应，镀层是常温常压下利用化学吸附沉积和机械碰撞使金属锌粉在工件表面镶嵌堆积而成[1]，所以人们认为机械镀锌镀层的致密性要低于电镀和热镀锌镀层，但机械镀锌镀层又表现出良好的耐腐蚀性能。

No tetracthyl thiuram (TETD or D2) molecule formed by oxidation on the surface. At the potential from -0.25 V on, the chemical adsorption of jamesonite occurred. In the presence of diethyldithiocarbamate, the interaction between jamesonite and diethyldithiocarbamate became obvious from 0.35 V on.

采用循环伏安电位扫描研究方法，研究了乙硫氮在脆硫锑铅矿表面的电化学作用机理，在其表面没有氧化形成四乙基二硫化秋兰姆（TETD或D2）分子；电极电位从－0.25V左右开始就在脆硫锑铅矿产生了化学吸附。

Since H〓S and SO〓 adsorbed on TiO〓 could react with each other and TiO〓 is the medium of their electron transfer, thus SO〓 could not be adsorbed quite strong on the active site of TiO〓, which makes it more resistant to sulfating and increase the stability of catalyst. Finally, the model and mechanism of the reduction of SO〓 by NH〓 to elemental sulfur is advanced as follows: on the sulfide catalyst, ammonia is decomposed to N〓 and H〓, and H〓 reacts with SO〓 to form the intermedium of H〓S; then H〓S and SO〓 react as Claus reaction on TiO〓 catalyst.

反应系统中过量水蒸气的存在使催化剂表面某些活性位被水蒸气抑制使活性和选择性有较大幅度降低，但这种影响是可逆的，不会造成催化剂永久性中毒；另外当单质硫和水蒸气同时存在时，在〓催化剂上能够生成硫化氢和二氧化硫，而且由于硫化氢和二氧化硫化学吸附能力不同而导致它们的脱附顺序不同，硫化氢的生成温度总是低于二氧化硫的生成温度，说明过量水蒸气的存在会导致氧化物催化剂上逆克劳斯反应的发生；而在硫化物催化剂上几乎没有硫化氢和二氧化硫生成，说明硫化物催化剂能够抑制逆克劳斯反应的发生。

The uptakes of H2 and CO on the Li-promoted Rh-based catalyst were almost the same as those on the Rh-Mn/SiO2 catalyst, which implied that most of Li was positioned on the support, and only a small part of the added Li was positioned on the top of Rh particles.

Li负裁量对Rh-Mn/SiO2催化剂上H2和CO的化学吸附量影响较小，这表明并非所有的Li都和Rh发生了相互作用，而是有相当一部分Li只是分散在载体SiO2上，并没有与Rh发生接触。
