隐性课程视角下高校德育课程建设初探

长久以来,我国高校德育一直都以显性教育方式为主导。但随着人们对当代高校德育发展和大学生思想品德发展的要求日益提高,仅仅依靠德育课程等显性德育方式显然是不够的,还必须运用除此之外的多种因素对学生施加德育影响,以提高德育教育的实效性。从目前我国高校德育课程的实施现状出发,在分析了隐性德育课程的内涵、特征及其构成要素的基础上,尝试性的对隐性德育课程的设计和建设提出了一点意见和建议,以期能为今后更好地开展和实施隐性德育课程提供参考。

面向电力安全的大面积停电事件情景构建方法研究

为了进一步提高各职能部门对大面积停电事件的应急处理能力,同时增强电力安全突发事件应急响应培训和演练的效果,采用了一种情景构建方法。基于相关案例、相关书籍收集整理出大面积停电事件中的重要情景;设计了情景库编码规则、分类方法和跳转关系。结合上海市电网实际情况,构建了大面积停电事件的具体情景,并基于"情景-应对"方式设计了大面积停电事件推演方案。     

新型二维材料MXene及MBene合成的研究进展

For exploring synthetic methods for MXene and MBene materials，the safer，greener and more reliable methods for synthesizing MXene have been proposed，and the preparation method of MXene using an organic solvent was pioneered. However，there are few reports on the synthesis of MBene experiments，and the feasibility of chemical etching was confirmed based on first-principles calculations. This article mainly reviews the research progress of two-dimensional transition metal MXene and MBene synthesis in recent years. The two-dimensional transition metal MXene with different elements was introduced to the corresponding synthetic method，and the intercalation stripping was also briefly introduced. Prospects for the future development and application of MXene and MBene were presented. We confirm that the excellent and stable synthetic structure of MXene and MBene is the premise of their development into application. We believe that with the deepening of research and the rapid development of synthetic technology in the field of material research，more MXene and MBene with good stability will be designed and synthesized，and the two- dimensional material family will be further developed.
