对未处理和经喷砂、凿毛、切槽界面处理后的预制超高性能混凝土(UHPC)与现浇普通混凝土(NC)组合试件进行双面剪切试验,记录加载过程中的剪切荷载与界面滑移,通过剪切荷载-界面滑移曲线分析不同界面处理方式对组合试件抗剪性能的影响.结果表明:界面处理显著提高了预制UHPC与现浇NC组合试件的界面抗剪性能;不同界面处理方式下组合试件的破坏模式主要分为3种;采用边长18 mm正方形钢丝网格凿毛处理的组合试件界面抗剪强度与抗剪刚度均最大,其界面抗剪强度为未处理界面试件的4.69倍;凿毛与切槽处理使组合试件拥有较好的界面抗剪性能,表现为延性破坏;界面粗糙度相近但界面处理方式不同的组合试件抗剪性能表现出明显差异;各组试件界面抗剪强度与抗剪刚度变化趋势大致相同.

U盘的广泛使用为计算机之间交换数据提供了极大的方便,但是在使用U盘的同时也存在着U盘可以未经允许而随意地读取的问题。针对这一问题,现有的技术手段主要通过软硬件加密的方式解决,但仍存在兼容性低、操作过程复杂、可移植性低等问题。为了解决这一问题,提出了一个基于单板计算机的U盘加密系统。该系统的设计以运行Linux操作系统的单板计算机为基本框架,采用了Linux统一密钥设置(LUKS)加密规范,按照高级加密标准(AES)为U盘上数据提供加密保护;通过媒体传输协议(MTP)为计算机提供安全的连接,为整套系统对计算机的连接提供极佳的兼容性。实验结果表明,该U盘加密系统可以为所有兼容USB大容量存储设备的U盘提供加密功能,也兼容Windows和Linux等常见操作系统,在确保安全性的同时具有极佳的通用性。

Tracking the dynamic surface evolution of metal halide perovskite is crucial for understanding the corresponding fundamental principles of photoelectric properties and intrinsic instability. However, due to the volatility elements and soft lattice nature of perovskites, several important dynamic behaviors remain unclear. Here, an ultra-high vacuum（UHV） interconnection system integrated by surface-sensitive probing techniques has been developed to investigate the freshly cleaved surface of CH3NH3PbBr3in situ under given energy stimulation. On this basis, the detailed three-step chemical decomposition pathway of perovskites has been clarified. Meanwhile, the evolution of crystal structure from cubic phase to tetragonal phase on the perovskite surface has been revealed under energy stimulation. Accompanied by chemical composition and crystal structure evolution, electronic structure changes including energy level position,hole effective mass, and Rashba splitting have also been accurately determined. These findings provide a clear perspective on the physical origin of optoelectronic properties and the decomposition mechanism of perovskites.
