摘要：铋（Bi）正成为无铅电子系统中的必要元素。或者通过“自然的”供应链，或者通过设计，铋应用到电子系统中。比如说，在SMT制造这一层次上，一块PCB板上就可能组装有一个或多个含铋的元件。这是因为，除铅（Pb）之外，铋是减少锡晶须现象发生的最有效的元素。而那些无需转向无铅系统的厂商可能会继续使用锡铅（SnPb），因而铋也仍可应用于锡铅系统中。关于锡铅和无铅系统中铋的作用，已经积累了大量的数据和事实；遗憾的是各种各样的感受、传言和误解甚嚣尘上。正确理解铋的特性租陛能参数，对于驱散各种传言的迷雾十分必要，对于无铅的最终成功也至为关键。应予了解的关于铋的角色与作用的相关方面包括：

摘要：The aim of this paper is the analysis of the supernatural elements in Kipling"s "The Mark on The Beast" (1890), Conan Doyle"s "Lot No. 249" (1892), and Wells" "The Truth about Peycraft" (1903) conceived of as the expression of the revitalisation of the Gothic imagery which, through the short story, serve to voice and exorcise late Victorian crisis, de-Constructing late Victorian identity. First, the complex nature of late Victorian Britain crisis will be deepened. Second, the short story will be focused on as an independent genre from the novel which mostly epitomized Fin de Siecle literary fantastic discourse. Finally, the short stories will be investigated as textual examples of what Brantlinger (1988) defined as Imperial Gothic, instrumental in voicing and exorcising the pressures of late Victorian crisis.

摘要：The significance of the trinity archetype and the number three is recurrent in religions and myths around the world. Within the trinity archetype, each element is both distinct from and symbiotic with the other elements—-that is to say, each stands apart from the others, but none can truly function alone. This can be seen throughout Greek mythology, for example, The Moirae and The Musai, and of course, through the Christian Trinity of Father, Son, and Holy Spirit. While the archetype of the trinity appears numerous times throughout the Potter series, at its very heart, the series is centrally focused on a triad of trinities: the Trio (Harry, Ron, and Hermione), the three Unforgivable Curses, and the three Deathly Hallows. It is the intersection of this triad of trinities—-this "supertrinity"—-that not only drive the Potter narrative, but connect the work so readily to the psyche of readers and fans; it is how we are harmonically programmed, in terms of understanding stories.

摘要：The design procedure is made for a mine shaft where permanent underground facilities are interconnected. The highly faulted grounds were identified using empirical and semi-empirical theories. Furthermore, the behavior types are presented. This paper presents excavation and support methods in such ground conditions and the calculations results show that the installation of the yielding elements have an effect on support elements and prevent shotcrete damage during the curing stage. Different numerical analyses carried out showed that, with the yielding elements installed, the total displacements increase but the final axial force reduces, and therefore, the characteristic compressive strength of shotcrete is not exceeded. The calculation results of ground loads and displacements on the designed support system are presented with a 3D numerical geo-mechanical model adopted for highly faulted ground surrounding deeper complex underground structures.
