The voltammetric dissolution of an iron-zinc alloy film, deposited potentiostatically from −0.2 to −1.4 V, was studied. Dissolution curves of the film at different sweep rates showed only one anodic peak, whose current density (jp) was higher than the divacancy current density, implying that Fe and Zn in the film dissolved simultaneously. Equations relating jp to sweep rate (v) and peak potential (Ep) to v, for the dissolution process of thick alloy film, were developed on the basis of Brainina's theory of pure metal layer dissolution. These equations were applied to the dissolution of Fe-Zn alloy film. The results obtained showed that the jp × v and Ep × v plots were linear, corroborating the equations developed based on Brainina's theory and indicating that this alloy dissolves as one metal. 相似文献

In view of the application of γ-AlON as transparent structural materials, it is significant to have a deep understanding of mechanical properties of γ-AlON as well as their response to external pressure. First-principles calculation combined with bond valence models was used to reconstruct Fd3m structure, and explore the composition and applied pressure dependence of mechanical properties of Al24−8/3xO24+8xN8−8x. The reconstructed Fd3m structure of Al24−8/3xO24+8xN8−8x was proved to be reasonable. The investigation demonstrated that the hardness and bulk modulus of bonds can be enhanced by increasing the ratio of bond valence to bond length and the bonds in octahedra contribute more to hardness and bulk modulus of Al24−8/3xO24+8xN8−8x. The applicability of the inferences was assessed by MgAl2O4 and c-Si3N4. It can be inferred that the inferences cannot be applied to other spinel-type compounds but also provide guidance to designing new spinel-type compounds with desirable hardness and bulk modulus. 相似文献

目的了解中药注射剂在临床应用中导致死亡的主要原因和特点。方法以国内公开发行的医药期刊中有关中药注射剂致死的病例报道为基础进行分析整理。结果致死病例报道涉及17种中药注射剂,以葛根素、双黄连、复方丹参、清开灵、柴胡、鱼腥草、茵栀黄等报道频率较高;严重过敏是中药注射剂致死的最主要原因,给药方法不合理、抢救时机与措施不当也与死亡有关。结论中药注射剂临床应用的安全性问题应引起医药人员的高度重视。 相似文献
