The factors of temperature and humidity influenced on film thickness and order of layer were studied, in which pulling speed and pulling times were also included. It showed that the thickness of single dip-coating film reached 0.23 μm ~ 0.625 μm, and the degree of order of surface layer were still holding much higher.b Adopting calcined or uncalcined mesoporous silica membrane as matrix, nano zirconia particles were assembled through ion exchange method and ion-template exchange method.

Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先，钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能，并且有明显的协同作用，从而能抑制部分点蚀核的产生；其次，钼酸盐复配缓蚀剂的使用，从电化学的角度分析，具有明显的钝化性能，且钝化区间较宽、维钝电流密度较小，从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化，得到有效的修复；最后，对于还有部分蚀孔发展成为闭塞腐蚀电池的情况，钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐，从而有效地减缓了点蚀的恶化，抑制了腐蚀的发展。

All patients demonstrated signs or symptoms of cerical myelopathy and/or radiculomyelopathy. The expansieopen-door laminoplasty technique described by Hirabayashi et al was performed in all patients, and foraminotomy was additionally performed in 18 patients who had accompanying foraminal stenosis.

用氟碳表面活性剂作为&共模板&，使高温合成介孔分子筛成为可能，只要选择合适的表面活性剂组合，使氟碳表面活性剂与碳氢表面活性剂可以形成混合胶束且在合成条件下它们与无机物种有合适的相互作用，则有可能在高温下合成一系列不同结构的稳定的介孔分子筛。

According to the experimental results, both the conducting area and material of current collector slices have great influence on the performance of micro PEMFC, especially the former one. The increment of cell's performance is finite by increasing the gas reheats temperature. The performance is better for open ratio 75% compared with 50% and 67%. The concentration polarization is improved by increasing the air flow rate at high current density and if the GDL diffusive capability in the latter cell could be promoted, the differences between these two cells' performances would be reduced.

由实验结果可知，集电片的导电面积与材料对於电池性能有显著的影响，尤其是前者；对於增加反应气体的再热温度，微型燃料电池增加的性能有限；双极板开孔率75%相较於开孔率为50%与67%有最佳的性能曲线；增加阴极气体空气的流量，可以改善高电流情况下的浓度极化现象，所以若我们能增加气体扩散层的扩散能力，则可以减少两者的性能差距。
