2017年11月,由华特·迪士尼电影工作室、皮克斯动画工作室联合出品的动画片《寻梦环游记》一经上映便受到广泛关注。片中展示的亡灵节庆祝画面令人耳目一新,许多中国观众通过这部影片认识并初步了解了墨西哥土著亡灵节,对其产生了浓厚兴趣。《寻梦环游记》对墨西哥的传统文化起到了良好的宣传效果,填补了人们对墨西哥土著亡灵节认识的空白,对亡灵节文化的传承与跨文化传播起到了极大的推动作用。反观与墨西哥土著亡灵节同为非物质文化遗产的我国的清明节,在影视宣传方面却缺乏内涵和吸引力。本文将以电影《寻梦环游记》为借鉴,从两个节日具有的相似文化内涵出发,探讨清明节影视宣传方面的不足之处,提出关于清明节节日文化内涵传承与传播的思考。 相似文献

对铑催化的1,6-烯炔环异构化反应进行了研究,这类反应具有较广的底物适应范围,在转化过程中,卤素发生了分子内转移。这类反应提供了一条新的立体选择性合成具有α-氯烯基结构的丁内酯、丁内酰胺、四氢呋喃、吡喃以及五元碳环等分子的方法。发展了两种不同的催化剂体系,即阳离子催化剂体系和中性催化剂体系。阳离子催化剂体系仅能催化顺式烯炔底物的环异构化,相反中性催化剂体系不但能催化顺反烯炔底物的环异构化,而且具有更广的底物适应范围。利用各种烯炔异构体,通过合适的控制实验对反应机理进行了研究。提出了涉及π-烯丙基铑中间体的可能机理,并且利用该机理对一些反应现象进行了解释。最后利用Suzuki偶联反应对产物进行了衍生。 相似文献
