公众史学的进一步发展要从公众史记录入手,公众史的核心是个人史,当代公众史记录核心要处理的是个人记忆文本化。当代人人能参与,是因为人人有一个大脑记忆数据库,当事人的主体认知有独一无二的价值。要重视老人历史记忆资源的采集,记下过往可以实现人生的痕迹化管理,文本传承的无限性可以弥补人类自然生命的有限性。口述史的可信度是有层次划分的。口述史是公众建立文本系统的最有效途径与手段,人人口述可以获得第一手的心迹与事迹信息。口述史可以将生活中的聊天与研究巧妙地结合起来,推开了一扇更大的"记忆之门",可让会说不会写的人留史。口述史的出现增加了一种普通人的历史认知表达形态,开创了直接的历史研究,公众参与与史家参与是不同层次的参与。

应用对冲火焰模型进行了甲烷/正庚烷对冲火焰结构与火焰中NO生成特性的数值模拟研究,探讨了NO的生成机理.贫燃甲烷/空气混合气和富燃正庚烷/空气混合气分别从两个对向布置的喷嘴射出,形成层流对冲火焰.结果表明:此对冲火焰为三重火焰,具有3个放热峰.保持正庚烷/空气混合气当量比不变,随着甲烷/空气混合气当量比增大,火焰宽度逐渐增大,NO排放指数逐渐减小.影响NO生成的最重要途径是快速型机理,其次是热力型机理,而NNH中间体机理和氧化二氮中间体机理的影响很小.随着甲烷/空气混合气当量比的增大,热力型机理影响增大,而快速型机理影响减小.快速型NO减少的原因是正庚烷/空气反应区的OH和H等自由基含量随着甲烷/空气混合气当量比的增大而减小.

目的系统评价针刺及电针对重症监护室肠内营养患者喂养耐受性及营养状况的影响。方法计算机检索万方数据库、中国知网、维普全文数据库、中国生物医学文献数据库、PubMed、Cochrane library、Web of science、Embase从建库至2020年8月1日收录的关于针刺或电针对ICU患者喂养耐受性及营养状况影响的随机对照研究(RCT),对符合纳入、排除标准的文献进行资料提取与质量评价,采用RevMan 5.4软件对喂养不耐受发生率及营养状况进行Meta分析,采用GRADE评价系统对结局指标进行证据质量评级。结果最终纳入15项RCT,合计1271例患者。Meta分析结果显示:与对照组常规治疗相比,针刺能够减少腹胀、腹泻、呕吐发生率,升高前白蛋白、血红蛋白水平(P0.05);电针能够减少患者腹胀、腹泻、呕吐、反流发生率,提高患者营养达标比例,增加患者喂养量、前白蛋白与白蛋白水平,减少加用肠外营养比例及胃残余量(P0.05)。根据GRADE标准,在针刺组与对照组比较方面,腹胀、腹泻、呕吐发生率为中质量证据,其余结局指标均为低质量证据;在电针组和对照组比较方面,便秘、误吸发生率、喂养量、前白蛋白水平、白蛋白水平为低质量证据,胃残余量和血红蛋白为极低质量证据,其余结局指标均为中质量证据。结论相比于常规治疗加肠内营养,联合针刺和电针治疗在减少ICU患者喂养并发症和改善营养状况方面有一定的优势,但是对于减少便秘发生率和增加喂养量,针刺优势不显著;对于减少便秘和误吸发生率、升高血红蛋白水平,电针优势不显著。

宏观语言学 2017年第1期5卷 1-23页

作者： qian Zongwu Yangzhou University China

Jinwen shangshu consists of the earliest documents handed down in China, and it is the classic of political history compiled no less than 2600 or 2500 years ago. The article makes a thorough analysis on object-preposed sentences, passive sentences,judgment sentences, and double-object sentences in Jinwen shangshu ( 《今文尚书》） . By comparing various sentence patterns and investigating them systematically combining with the development and the changes of the documentation language, it sums up some syntactic characteristics of Jinwen shangshu as well as the the evolution law of syntactic forms in the documentation language, and it is of reference value to the study of the history of Chinese grammar.
