摘要：1小池怎么也想不到,自己的非洲之行会和一只大猩猩产生奇妙的缘分。这一切还要从那场改变他生活的车祸说起。当那辆大卡车撞向他和妈妈乘坐的无人驾驶汽车时,汽车的智驾系统偏偏出现了瞬息的迟滞。在这生死瞬间,妈妈用自己的身体死死护住小池,给了他一线生机。

摘要：第二外语的学习与探索备受关注,其学科设计与研究更是刻不容缓。一直以来都是学生遵从学校的课程设计与安排的做法已不符合当代社会发展所倡导的"以教师为主导,学生为主体"的教育理念。本文从学生所关心的几个问题出发,探讨地方高校英语专业的第二外语学科设计,以提高第二外语在学生心中的影响力和学生学习二外的积极性。

摘要：桥头搭板作为过渡性措施,以缓解桥头突变性跳车以及将桥头差异沉降分散在一定距离范围内,有较好改善效果,本文通过对高速公路桥头搭板静载和动载试验进行研究,对桥头搭板的结构形式的合理性,以及试验桥头的行车舒适性进行分析。

摘要：多孔有机聚合物(POPs)是一类新型功能高分子材料,具有高比表面积、良好的稳定性及易于功能化等优点,已在气体存储与分离、传感、有机光电和多相催化等领域表现出潜在的应用。本文综述了在可见光激发下,多孔有机聚合物作为非均相光催化剂催化有机转化的研究进展,分析了多孔有机聚合物光催化剂的结构设计理念,总结了光催化有机反应的类型及催化性能,最后对多孔有机聚合物在光催化有机合成中的应用前景进行了展望,希望能够给予从事相关工作的科研工作者一定的思路和启发。

摘要：高校外语教学的课程思政建设是当前外语教学研究热点之一。本研究以北京外国语大学文秋芳教授团队构建的POA产出导向法为理论依据,探索基于POA教学法的高级法语课程设计思路,尝试深挖教材和课程各环节的思政切入点,融入《理解当代中国》系列教材的内容,探讨如何在高级法语课程教学中实现知识传授、能力提升和价值引领的多重目标。

摘要：阐述了生态环境保护的公路选线的原则及生态环境保护的公路选线的步骤。

摘要：Sluggish kinetics of anodic hydrogen oxidation reaction(HOR)in alkaline media,which arises from the two orders of magnitude lower HOR activity in alkali than that in acid media for platinum group metals,hinders the commercial implementation of anion exchange membrane fuel cells(AEMFCs).Consequently,the development of platinum-based catalysts combined with high efficiency and durability is urgently ***,we report a facile route for the synthesis of ternary PtRuTe alloy nanofibers with Pt atomic ratio of only 11%via a simple galvanic replacement *** optimize the adsorption strength of platinum and ruthenium towards hydrogen and hydroxyl species by regulating the electron donation from tellurium to platinum and ***,the obtained trimetallic alloy catalyst exhibits an impressive kinetic current density of 30.6 mA cm^(−2)_(geo) at 50 mV and an exchange current density of 0.426 mA cm^(−2)_(metal),which shows 3.0-and 2.5-fold enhancement compared with the commercial Pt/C in alkaline electrolyte,***,the catalyst also demonstrates excellent stability with merely 5%activity attenuation after 2000 potential *** work offers new pathways to boost alkaline HOR by rationally designing multicomponent alloys.
