摘要：《送元二使安西》这首诗以送别为主题，前两句写景，后两句叙事，诗人别巨匠心地借别筵将尽、分手在即时的劝酒，表达出对友人的留恋、关切和祝福。本课教学以“读诗句，想画面，悟诗情”为教学重点。创设情境，让学生充分展开想象，并用自己的语言描述古诗所描绘的画面，学生自由地，充分地与文本、诗人对话，在师生互动的品味中体会一份浓浓的送别情。与此同时，力求“重文本”又“超文本”，通过学法的归纳，让学生自主学习《谢亭送别》，真正使学生做到“主动探究，团结合作，学以致用”。

摘要：叶圣陶先生曾道:“略读的略字一半系就教师的指导而言,只需提纲挈领的指导;一半系就学生的功夫而言,还是要像精读那样仔细咬嚼。”我们可以采取板块式推进,以抓住课文主要内容为基本目的,粗略地、有所侧重地学习,正如就教学效果而言“精读是准备,略读才是应用”。而略读课文前面的“提示语”恰恰就是专家的指引。

摘要：目的研究双线盾构施工过程对邻近深基坑位移的影响,为相关隧道施工提供参考.方法笔者结合某地铁区间双线隧道,使用Midas GTS岩土有限元分析软件建立模型,进而分析盾构施工对邻近深基坑围护结构的影响.结果盾构施工完成后地下连续墙的水平位移增加了5.48 mm;随着掘进压力的逐渐增大,地下连续墙的最大水平位移值也在不断增大;随着千斤顶推力的不断增加,地下连续墙的水平位移呈现出不断减小的变化趋势;随着注浆压力增大,地下连续墙的水平位移反而越小,但减小程度较小.结论盾构施工对邻近基坑的围护结构产生的变形不可忽略,在施工设计及施工过程中应充分考虑并予以关注.

摘要：Hollow metal-organic frameworks(MOFs)and their derivatives have attracted more and more attention due to their high specific surface area and perfect morphological structure,which determine their large potential application in energy storage and catalysis ***,few researchers have carried out further modification on the outer shell of hollow MOFs,such as the perforation modification,which will endow hollow nanomaterials derived from MOFs with *** this paper,hollow MOFs of MIL-53(Fe)with perforated outer surface are successfully synthesized by using SiO2 nanospheres as the template via a self-assembly process induced by the coordination *** tightly packed mesopore structure makes the carbon outer shell of MOFs thinner,thus realizing the in-situ transformation from MOFs to hollow Fe3 O4/carbon,which exhibits perfect capacity approaching 1270 mA h g-1 even after 200 cycles at 0.1 A g-1,as an anode material in lithium ion batteries(LIBs)*** research provides a new strategy for the design and preparation of MOFs and their derivatives with multifunctionality for the energy applications.

摘要：本文阐述了实验教学对培养学生的综合能力和科学素质重要意义,介绍了近年来环境工程专业实验教学改革与建设经验:调整教学计划,增加自主开发的综合性、设计性和探索性新实验。实践证明,该类实验受到了学生的普遍欢迎,对培养学生的创新能力起到了积极的作用。
