　　Oxygen diffusion is the main form of transportation in the preparation process of polycrystalline superconductor YBa2Cu3O7(YBCO)thin films.Study of the diffusion of oxygen ions in the grain boundaries,is not only necessary for refining the preparation technique of YBCO film,but also very significant for deep understanding of the mechanism of its superconducting current carrying.

热缺陷对复合材料薄板结构屈曲承载力的影响分析
复合材料薄板结构广泛应用于航空航天、建筑等工程领域。在实际工程使用中，由于制造工艺、工作环境等因素，往往会局部受热产生局部热缺陷。热缺陷使结构整体或局部表面温度升高，通过热传导的形式将能量传递至结构内部，使结构内部产生不均匀的温度场，温度升高使材料的热力学性能发生改变，热膨胀受到约束将使结构产生热应力，进一步降低结构的屈曲承载能力。
