High energy consumption has seriously hindered the development of Fenton-like reactions for the removal of refractory organic pollutants in *** solve this problem,we designed a novel Fenton-like catalyst(Cu-PAN3)by coprecipitation and carbon thermal *** catalyst exhibits excellent Fenton-like catalytic activity and stability for the degradation of various pollutants with low H_(2)O_(2)*** experimental results indicate that the dual reaction centers(DRCs)are composed of Cu-N-C and Cu-O-C bridges between copper and graphene-like carbon,which form electron-poor/rich centers on the catalyst surface.H_(2)O_(2)is mainly reduced at electron-rich Cu centers to free radicals for pollutant ***,pollutants can be oxidized by donating electrons to the electron-poor C centers of the catalyst,which inhibits the ineffective decomposition of H_(2)O_(2)at the electron-poor *** therefore significantly reduces the consumption of H_(2)O_(2)and reduces energy consumption.

关于唐宋书学丛纂所存“笔法谱系”的研究,以往尤重其历史生成而忽视后世赓续的相关问题;该“谱系”供以赓续的内容存在“复合”和“精简”两个范畴,但因皆具臆衍属性,遂可视为是一种基于部分现实但不等同于现实的书史之“相”。而后世则将其追认为“实”,并呈现出代际赓续的现象。然目的却不在赓续本身,而是为解决实际问题和寻求自身笔法的合法性。由此所进行的调整、附益、删补等过程,即是一种“史相之相”;该赓续过程无疑促进了笔法理论的继拓,也催发了将误读与异化归为创造的多向度结果,究其关键即在于对其中“相”与“实”取舍的分辨及权衡。

唐宋四部书学丛纂中蕴隐着繁复且具有整体性的“笔法谱系”,本文从明晰其概念的基础认知切入,通过对楷模之间笔法关联的归纳与分析,发现楷模的区位、距离、方向是决定“谱系”空间构成的重要因素。并通过考索“谱系”的具体内容,得知“法传”仅为表象,而“人传”则为实质性内容。继而通过探究其文本叙述的顺序、模式、频率等,认为该“谱系”是文献中被认定为具有“必然”属性的诸多笔法关联所组成的“偶发性”集合体,体现了古代笔法理论中“知识”的生成逻辑与笔法流传“有序”的朴素认知,以及笔法“正统”与否的思维范式。

就在十余年前,人们还普遍认为胸腔内注入纤维蛋白溶解剂(纤溶剂)治疗胸腔感染是无效的。随着临床研究证据的逐渐积累,现在国际上已经达成了共识,推荐以胸腔内同时注入纤溶剂和脱氧核糖核酸酶作为胸腔感染的初治用药,或作为外科手术后的后续治疗方案。推荐使用剂量为:组织纤维蛋白溶酶原激活剂10 mg/次,2次/d;脱氧核糖核酸酶5 mg/次,2次/d。建议今后的研究重点将在于摸索出更优化的用药方案,并开发更有效的治疗药物。

纪录片的发展与剧情片的虚构手法息息相关,衍生出许多亚类型,如伪纪录片。因缺乏判定标准体系,伪纪录片的边界模糊,以至于相关研究形成了混乱的案例库。简·罗斯科和克雷格·海特关于伪纪录片的研究建立起了一个相对立体、全面且清晰的标准与体系。该体系以事实性话语作为区分,通过四个角度--电影制作者的意图、文本的建构和为观众搭建的角色建构、对事实性话语的影响来研究、辨析伪纪录片,进一步提出了伪纪录片的三个层级:戏仿、批评、解构。以电影叙事学为横向,以四个角度为纵向,对比观测伪纪录片与剧情纪录片、剧情片、纪录片的风格差异,四种类型影片的文本的建构风格相对统一,与四个角度和三个层级的体系相吻合,形成了对应的、不同的风格特征。为数不多的特例也意味着该体系提供的边界还有随着新创意或新技术延展的可能。伪纪录片的根目录是纪录片。纪录片包含的元问题,揭示了其本身及其亚类型的复杂性和多样性,也反映了电影创作与社会、文化背景的深刻联系。伪纪录片作为一种文本建构方式,可以在风格层面上形成对真实的追求、探索或可能。
