X-ray photoelectron spectroscopy was used to investigate the content and chemical valence of chromium element,and the content of compounds in chromate passive film formed on commercial tinplate via a cathodic electrolytical treatment.

用X射线光电子能谱(X-ray photoelectron spectroscopy，XPS)分析的方法，对铬酸盐钝化镀锡钢板的正常表面及缺陷点处铬元素的含量、价态以及由铬元素组成的化合物进行了研究。

The formatin of an insulating layer of TiO2 at the interface between the metallic base and the active coating resulting in the increase of oxide film resistance, the catalyst consumption induced the increase of charge transfer resistance of faradaic process evidently, which lead to the deactivity of the anode.

结果表明，阳极具有优良的耐析氯氧反应能力；钛基体逐渐形成TiO2的钝化膜使阳极的氧化物膜电阻增大，活性组元的消耗使法拉第电荷传递电阻增加，这两者最终导致阳极失效。

Based on 3D steady and incompressible N-S equation and k-ε turbulent model, the aerodynamic performance of three different design options of 160 km/h container flat wagon was analyzed and compared using finite volume method. The three design options are as follows: the first design option has no headwall and the side surface of side beam is flat; the second and the third both have headwall and high side beam, and the side surface of side beam of the second is obtuse, while the third is cambered.
