Abstract: 目的比较犬颈总动脉和股静脉持续输注异丙酚至脑电静息时循环、呼吸变化及异丙酚的用量。方法杂种犬8条,通过颈总动脉或股静脉持续输注异丙酚直至麻醉深度指数(csi)等于零,并维持csi在0-5之间波动持续60min停药。记录意识消失、恢复时间及异丙酚用量,观察犬血流动力学和呼吸的变化。结果达脑电静息所用时间和停药后苏醒时间,颈总动脉给药明显快于静脉给药(p<0.05)。颈总动脉和股静脉给药在意识消失时、csi=0-5持续10s、30min和60min时异丙酚的用量分别为(76.1±24.3)mg和(146.9±48.3)mg(p=0.000)、(221.3±47.4)mg和(353.3±89.2)mg(p=0.000)、(474.9±122.5)mg和(845.8±206.8)mg(p=0.000)以及(721.3±204.0)mg和(1401.4±410.4)mg(p=0.000)。在脑电静息各时点,颈总动脉给药对平均动脉压和呼吸的影响与静脉给药比较统计学差异非常显著,动脉给药血流动力学和呼吸指标变化更平稳。结论异丙酚颈动脉麻醉至脑电静息比静脉麻醉用药量少,对循环、呼吸影响小。更多还原
訊息來源可信度、情感認同與涉入程度對大學生採信消費性網路謠言之影響 The Influence of Source Credibility, User’s Affection and Involvement on College Student’s Belief toward Internet Rumors  [PDF]

Journal of Educational Media & Library Sciences , 2007,
Abstract: 本研究以訊息「來源可信度」、「情感認同」,與「涉入程度」作為變項,探討大學生在採信消費性網路謠言的影響程度。研究群希望藉此喚醒大學生對網路訊息的自覺,並將研究成果提供企業產品行銷及個人防堵謠言之參考。本研究結果發現:一、發訊者及訊息內容是否具專家權威性,將影響收訊者對消費性網路謠言的判斷;二、不同情感認同的收訊者在採信網路謠言的程度上,並沒太大差異;但在消費行為上卻稍有差異;三、涉入程度在來源可信度與情感認同兩方面,對於大學生採信消費性網路謠言均有正向影響。 The purpose of this study is to investigate the correlative causality of college students’ belief to consuming network rumors. “Source credibility,” “affection” and “involvement” are operated as the main variable effects on college students’ belief to these rumors. By using “involvement” as a moderator, this study analyzes its correlation with the other factors. This study is designed to awake college students’ attention to network messages, and to provide suggestions for the enterprises. The findings of this study include: 1. both source credibility and involvement have positive effects on the college students’ belief to consuming network rumors; 2. affection has part of effect on the college students’ belief to consuming network rumors, but with no causal relation; and 3. both source credibility and involvement have positive effects on the college students’ belief to consuming network rumors under different involvements.

Abstract: 针对高速光纤交换网络高质量的交换服务需求,提出了一种适用于信令寻径式高速光纤通道交换机的信令降频方法。该方法采用一套特殊的序列码对信令帧内容进行编码后传输,以达到信令帧信号频率成倍降低的目的,使交换机无需借助串并转换器对高频信令帧进行降频,就能够直接识别信令帧内容。试验结果显示,采用信令降频方法后,交换机的结构显著简化,可靠性得到很大提高,并且硬件成本大大降低。

rna编接  [PDF]

Abstract: 本文概要介绍了锥虫基因表达与调控的一种普遍而独特的方式:rna编接(rnaediting)。初级转录本经rna编接系统加工后,成熟rna中插入了数目不等的、非基因组编码的尿嘧啶核苷酸残基(u)并切除了某些由基因组编码的u序列。编接插入的“额外”u序列可占成熟rna的60%左右。这一现象的发现,向人们提出了这样的问题:遗传信息都存在于基因组dna序列中吗?是否还存在其它形式的遗传物质?

朱东润
- , 2015,
Abstract: 本文为已故朱东润先生(1896~1988)未刊稿,约撰写于1940年6月后不久。此前因教学安排,朱先生完成《史记考索》一书,以文献考订为主,但他的学术兴趣则更多地关注中国历代传叙文学研究,撰《传叙文学之变迁》加以探讨,其中包括本文,是有关人物传记与全书评骘之专论。本文谈到正史的范围,讲到史传与传叙文学的联系与区隔,《史记》互见体例之运用及其局限,特别讨论到《管晏列传》、《魏公子列传》、《魏其武安侯列传》以及项羽、刘邦本纪之人物叙写的成就和偏失。本文是朱先生学术鼎盛时期的力作,笔力健旺,议论风发,分析细致,识透纸背,显示融贯东西、参悟古今的气象格局。《史记》 传叙文学 互见 晏婴 信陵君 项羽 刘邦 古代史家和传叙家底分野,常常不清,希腊、罗马时代如此,中国古代也是如此。我们误认古代的史家就是传叙家,所以常说史传,我们也误认司马迁、班固底著作是传叙底标准。这实在是一种混乱的观念,现在必须看清,所以要把《史记》纪传底意义说明白,连带也把一切史家底传叙谈一下,以后就可以把史家底著述,完全搁下了。这一章本来可算是节外生枝,但是为着澄清一般的观念,还是必要。
Abstract:This article is an unpublished manuscript of the late Professor Zhu Dongrun, probably written in June, 1940. Before that Professor Zhu had finished his Shiji kaosuo (textual research of Shiji) as part of his teaching arrangement, but he concerned more about the biographical literature in ancient China. He wrote Revolution of Biographic Literature, including this article, which is a monograph on biographies and entire books. This article comes to the scope of official history, discusses about the relation and differences between historical biography and biographical literature, and gives insight into “Guanyan liezhuan”, “Weigongzi zhuan”, “Weiqi wuanhou zhuan”, and the pros and cons of the biographic narration in Xiangyu benji and Liubang benji (emperors' biography). It is one of the best works during Professor Zhu's academic peak, vigorously and critically written, with meticulous analysis and deep insights. A mind integrated the West and East, the past and present is demonstrated in the article.
