To investigate the pitting and metastable pitting rules of type 304 stainless steel, potentiodynamic polarization method was employed to study the behavior of metastable pitting and stable pitting on 304 stainless steel in sodium bromide solution and borate/phosphate buffered bromide solutions. The influence of the concentration of Br-、the pH value、the buffer capacity and general environmental factor to pitting potential and metastable pitting was studied as well.

为了更深入地了解304不锈钢的稳态及亚稳态孔蚀规律，本文采用动电位慢扫描法测得了304不锈钢的阳极极化曲线，研究了不锈钢在纯溴化钠溶液及含溴化钠的硼酸盐或磷酸盐缓冲溶液中的亚稳态孔蚀以及稳态孔蚀行为，分析了溴离子浓度、pH值、缓蚀性阴离子、以及缓冲容量和综合环境因子对孔蚀电位以及亚稳态孔蚀特征参数中的形核数目、峰值电流、生长寿命的影响。

结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

In this process, the discharge process of single point to point contact is transformed to the process of both point to point contact and the overall surrounding contact of sphere Ni through the self redox reaction, thus making a highly efficient electron transfer process. In this dissertation, the catalytic electrolysis mechanism is discussed. The influence of various parameters (e.g. kind and concentration of catalyst, reaction temperature and electrolysis duration) on electrolysis were investigated.

本文首次提出了以KMnO_4为代表的高锰酸盐作为电解过程电子传递的媒介，通过锰盐自身氧化还原反应的参与，在阳极和溶液中的球形Ni_2之间建立起高效的电子转移过程，使球形Ni_2和阳极之间单一的固体之间的点点接触放电，转变为点点接触放电和球镍与溶液全方位包围接触放电过程，大大提高了电解过程的效率。

In order to improve their water solubility, 4"-fatty amido-3"-sodium carboxylate azobenzene-4-sodium sulfonates were synthesized. They are azo compounds with two hydrophilic groups of carboxyl and sulfonyl. They decrease the surface tension in dilute solution slowly, and show some surfactivity, but are not surfactants. The probable reason is their relative strong hydrophile. Furthermore, their colors are not fresh and far from our destination.

为了改善其水溶性，改用对氨基苯甲酸为原料合成了4′-脂肪酰氨基-3′-羧酸钠偶氮苯-4-磺酸钠盐，以偶氮结构为主的亲水基团上连有羧酸基和磺酸基两个亲水性较强的基团，但可能由于其亲水性太强，在稀溶液中只能缓慢地降低溶液的表面张力，具有一定的表面活性，但不是表面活性剂，而且颜色不鲜艳，距离我们的目标较远。

传统的柠檬酸盐镀金工艺前处理采用稀盐酸或稀硫酸活化，活化液可能被带入镀金溶液，造成SO2-4、Cl-积累，严重影响柠檬酸镀金溶液的稳定性和镀层质量。

After SBF solution cultivation for some days, the Ca/P coating was very easily deposited on the porous surface that was constituted of cystiform polygon made up with irregular nanometer circles like honeycomb. The energy spectrum showed that n/n atom ratio is about 1.61:1 which is very similar to that of HA and human bone. The active surface of the porous titanium after acid-alkali treatment and SBF solution condition which calcium-phosphorus ions was supersaturated induced the formation of Ca/P deposition layer.
