《野草》与鲁迅心灵世界的悖论

鲁迅思想的矛盾性集中体现在他的《野草》中。这种矛盾并非简单的二元对立,而是充满着结构张力的逻辑两难,它们相互依存相互冲突,纷繁复杂的呈现在文本中,使得《野草》表现出多义特征。     

随机脉冲控制下超混沌复Lü系统的渐近稳定性

基于脉冲微分方程的稳定性理论,研究了具有随机信号的脉冲作用下,超混沌复Lü系统的渐近稳定性.给出了确定性和随机脉冲作用下系统达到渐近稳定的判据.并且提出了在等距脉冲间隔下,系统达到稳定的区域估计值.通过数值算例,讨论了确定性脉冲和随机脉冲的异同点,并证实,此方法对于外界噪声是比较稳健的.     

契诃夫与鲁迅：在医生和作家之间

契诃夫是19世纪俄国批判现实主义最后一位作家,鲁迅是20世纪中国新文学最初一位作家。契诃夫是医学院校培养出来的医生,鲁迅在医学院校接受过专业的医学教育。他们用医生的视角认识社会,用医学的原理透析人生,用医生之手解剖形象。在医生和作家之间考察,是对契诃夫和鲁迅予以准确定位的重要途径。     

线性反馈、非线性反馈控制策略实现Lü系统混沌同步

对混沌系统的同步问题进行了理论分析,并证明了线性反馈控制同步规则.基于Lyapunov函数提出了基于部分变量的非线性反馈控制同步规则,其特点是仅需对响应系统部分变量施加控制就可以实现同步,具有较好的鲁棒性和抗干扰性,而且同步速度较快.     

自我本味的解剖——《离婚》症候式分析

鲁迅《离婚》的难读难解性在学术界几乎是一个共识,而且在很大程度上存在着误读。文章从文本的表层深入到文本内部,用症候式分析方法解读《离婚》,得出《离婚》的症候:爱姑形象对封建制度的反抗是显在的,而鲁迅无意识之中丑化爱姑,消解了爱姑的反抗性,把爱姑的反抗塑造成不成熟的,无意识流露出对爱姑的厌恶情绪。接着从鲁迅的爱情、婚姻生活及其思想矛盾性里寻求鲁迅的情结所在,反映了鲁迅潜意识之中是对自我思想矛盾性的追问和反省。

Ultimate load carrying capacity of the Lu Pu steel arch bridge under static wind loads

This paper investigates the ultimate load carrying capacity of the Lu Pu Bridge under static wind loads through the spatial finite element model. Both geometric and material nonlinearities are involved in the analysis. The Lu Pu Bridge is a long-span half-through-type steel arch bridge with a 550 m-long central span under construction in Shanghai, China. This will be the longest central span of any arch bridge in the world. Three load combinations are used in the ultimate load capacity analysis of the bridge. Combination I: combined dead and live loads over the entire bridge. Combination II: combined dead and wind loads. Combination III: combined dead load, wind load and live load over the entire bridge. Ultimate load capacity of the bridge is first investigated under load combinations I and II. Attention is paid mainly to investigate the load capacity of the bridge under load combination III. In the case of load combination III, the influences of several parameters (i.e., loading sequence, three components of wind loads and wind loads of individual bridge element) on the ultimate load capacity of the bridge are discussed. It is concluded that wind loads result in significant reduction in the ultimate load capacity when applied wind loads become large.     

陆良与保山盆地第三系浅层气田开发规律探讨

以云南陆良、保山盆地第三系浅层气田为例,结合国内外浅层气田的开发经验,探讨浅层气田的开发规律,以指导同类气田的开发.浅层气田一般气藏规模小,气柱高度小;产层疏松,大部分气藏为有水气藏;生产时气藏无水生产时间短、稳产时间短,气井容易出水、出砂,其开发规律明显区别于中深层整装构造型气藏.针对陆良、保山浅层气田生产表现的"三低"(低单井日产水平、低采气速率、低采出程度),气井见水快,井筒容易积液,产层容易出砂,出水大则出砂也大等特点,提出以下对策:(1)依据多井小压差原则,进一步完善井网,避免频繁激动气井;(2)严格按.规定压差生产,及时确定气井"三稳定"的最佳工作制度,生产中;(3)尽量减少或杜绝井口气量调节,更不能轻易关井;(4)一旦发生气井水淹,尽快采取措施,避免造成井底或地层的严重污染,给复产带来困难;(5)加强气田生产测井、试井、产能测试,取全取准各项资料,及时进行动态分析与动态监测,对生产中出现的问题做到早发现、早解决.从而保证气田平稳、正常开采.     

Superior self-paced memorization of digits in spite of a normal digit span: The structure of a memorist’s skill.

Over the last century many individuals with exceptional memory have been studied and tested in the laboratory. This article studies Chao Lu, who set a Guinness World Record by memorizing 67,890 decimals of pi. Chao Lu’s superior self-paced memorization of digits is shown through analyses of study times and verbal reports to be mediated by mnemonic encoding and retrieval processes. Furthermore, Chao Lu’s development of his superior memory for decimals of pi is consistent with his engagement in thousands of hours of memorization. In contrast to most other studied memorists, who have digit spans over 15 digits, Chao Lu exhibited a digit span in only the normal range. Implications for different types of memorization skills and associated practice activities are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

王澍：普利茨克奖的“尾声”

王澍获得了2012年度的普利茨克奖,该奖发源于美国。是业界公认的、颁给当代建筑师的最高奖项。但当一位建筑师获得这一荣誉之后,会发生什么事情呢？本文通过对以往这一桂冠的获得者的后续发展、世界范围内的地标建筑及“明星建筑师”现象的考察,来推测这位来自中国杭州的建筑师王澍日后的发展轨迹。这篇文章建立在一篇访谈的基础上,指出王澍的作品不管是在全球范围内,还是在中国本土,都将对当代建筑产生有意义的冲击。
