“马保国事件”消解了武术网络媒介形象,表现为荒诞式的话语呈现、断裂化的媒介记忆、消遣式的网民参与,主因是基于视觉媒介的武术欣赏结构变化、媒介奇观效应下的围观扩散、权威话语缺席下的情感消费。在武术与网络的交互关系中,媒介导致武术形象多维消解,集体参与加速武术形象崩解,武术符号形象与现实发展脱节。遏止武术网络形象崩解并重塑积极形象,需利用媒介搭建武术认同基础,推动武术形象正常化发展,多维度强化武术教育。
The OCF3 group has good metabolic stability,suitable lipophilicity and special electrical properties,which can modify the properties of drugs and material molec
Chiral phosphorus ligands have played a crucial role for the recent advances in asymmetric catalysis.This review summarizes chiral phosphorus ligands developed from the Laboratory of Professor Xumu Zhang in the latest 25 years.A number of iconic phosphoru
Persistent luminescence materials(PLMs)are a class of unique luminescent materials that can remain luminescent for a few milliseconds to days without constant excitation.By virtue of the super long decay time,PLMs have been extensively explored in biosens
在《道德经》英译中采用何种翻译策略以及如何操作,将直接决定取得何种语境效果。关联理论提出的四种语境效果——语境暗含、加强、矛盾、削弱,可以有效涵盖复杂的人类交际和充分阐释《道德经》英译行为、过程和结果。在《道德经》英译中采用三个英译策略——归化策略、异化策略、妥协策略,旨在使《道德经》英译文在英语读者身上取得语境暗含和加强这两种正面语境效果。在《道德经》英译中,三个英译策略的具体运用层面是不同的:归化策略始终针对目的语形式表征,异化策略始终针对老子思想内容本色表征,妥协策略则是对原文某些局部措辞或结构进行
中国古代有“辩者”之称,无“名学”之名.传统知识分类体系有“名家”之位,无“名学家”之说.“名家”如何在近代学科分类中演变为“名学”和“名学家”?随着晚清分科体系的
Main observation and conclusion The enantioselective hydrogenation of endocyclic enones has been a historical problem for homogeneous catalysis.We herein report an efficient method to reduce endocyclic enones with molecular hydrogen.Catalyzed by a rhodium
