英汉习语的语用对比与语用等效翻译

习语是语言的精华。通过一系列英汉习语之间的语用对比,本文探讨了英汉习语的具体语言表现形式的异同和各自特定的文化内涵。基于此,笔者以语用等效翻译理论为依据,通过若干例证的剖析,提出了英汉习语翻译的语用策略,以期在目的语中再现原语习语的语用语效。     

Hierarchical models for failure analysis of plates bent by distributed and localized transverse loadings

The failure analysis of simply supported, isotropic, square plates is addressed. Attention focuses on minimum failure load amplitudes and failure locations, von Mises＇ equivalent stress along the plate thickness is also addressed. Several distributed and localized loading conditions are considered. Loads act on the top of the plate. Bi-sinusoidal and uniform loads are taken into account for distributed loadings, while stepwise constant centric and off-centric loadings are addressed in the case of localized loadings. Analysis is performed considering plates whose length-to-thickness ratio a/h can be as high as 100 （thin plates） and as low as 2 （very thick plates）. Results are obtained via several 2D plate models. Classical theories （CTs） and higher order models are applied. Those theories are based on polynomial approximation of the displacement field. Among the higher order theories （HOTs） HOTsa models account for the transverse shear deformations, while HOTs models account for both transverse shear and transverse normal deformations. LHOTs represent a local application of the higher order theories. A layerwise approach is thus assumed： by means of mathematical interfaces, the plate is considered to be made of several fictitious layers. The exact 3D solution is presented in order to determine the accuracy of the results obtained via the 2D models. In this way a hierarchy among the 2D theories is established. CTs provide highly accurate results for a/h greater than 10 in the case of distributed loadings and greater than 20 for localized loadings. Results obtained via HOTs are highly accurate in the case of very thick plates for bi-sinusoidal and centric loadings. In the case of uniform and off-centric loadings a high gradient is present in the neighborhood of the plate top. In those cases, LHOTs yield results that match the exact solution.     

高职院校大规模在线教学成效、问题及提升策略研究

高职院校史无前例地实践了整个学期的师生居家式大规模在线教学,不仅挑战了课堂教学实践能力的极限,也是对我国40年来高职教育信息化建设成效的最强考验。作为“疫情”特殊时期课堂教学的应急替代方案,高职院校大规模在线教学化解了时空分离状态下的教学供需矛盾,交出了有效度又有温度的可喜答卷,用实践证明了在线教学有能力完成课堂教学任务,保障了“停课不停教”政策底线,树立了在线教育发展史上的里程碑。社会多主体协同为高职院校开展在线教学提供了所需的海量网络学习资源、多样化学习工具、虚拟化教学环境,教师转变角色当网红,学生相聚线上渐入佳境,以灵活的自组织教学方式实现在线教学质量超预期。变革教育领域深层“教学惯性”和师生“默契”教学心理场域并非朝夕之功,当前要以“身份”合法化赋予高职院校在线教学的社会基础,协同共建适切的优质在线教学资源,赋予教师在线教学人机结合、虚实叠加的协同组织者角色,以教学活动为中介统合在线教与学,培养学生自主在线学习能力,以情感为纽带协同家校、师生共同体、社区维系在线教学,为高职院校全面返校复课后线上线下协同的“混合教学”做好充足准备。

一类未定式的计算方法探究

未定式的计算是极限计算的重要组成部分．对于未定式1^∞,在满足一定条件下,可通过适当变换后再运用洛必塔法则直接计算．但洛必塔法则求解未定式既非万能,也非最佳。当该条件不满足时,洛必塔法则不能直接使用,可借助高等数学中的重要极限,选择凑构法、等价无穷小替换法及泰勒式展开法等来计算,从而巧妙地得到问题的解．
