基于粒级分离的长江口及邻近陆架沉积物磁性特征及其环境意义

在粒级分离的基础上,对长江河口及邻近陆架22个表层沉积物进行了磁学表征,探讨了磁性特征对物源、输运、沉积动力等环境信息的指示意义.研究结果表明,长江入海泥沙、残留砂及废黄河物质是长江口外水下三角洲及邻近陆架沉积物磁性特征的主要物源影响因素,但3者的空间分布不同.沉积物磁化率(x)、饱和等温剩磁(SIRM)、硬剩磁(HI...     

Recent Progress on Fabrication of Thermal Conductive Aluminum Nitride Fibers

Among nitride fibers, aluminum nitride(AlN) fibers have been developed for various advanced applications due to their mechanical flexibility, high thermal conductivity, and excellent electrical insulation and chemical stability. This article presents an overview on the recent progress of AlN fibers. The properties of AlN, particularly the thermal conductivity of AlN in polymer matrix composites are introduced. Afterward, two major approaches, carbothermal reduction and nitriding polycrystalline ...     

从《驯悍记》解读“悍妇”形象

对莎士比亚《驯悍记》中的彼特鲁乔和凯瑟丽娜进行了驯悍者与悍妇的分析,主要运用女性主义的相关理论,以及表演和易装等理论从更深的层面剖析了悍妇形象产生的根源、表现和影响,以此呈现出控诉这个父权社会的最强音—悍妇。
