相声艺术中的捧与逗

相声是一门通过捧哏和逗哏制造笑料的艺术。捧逗艺术凸显了相声的艺术本质:一捧一逗形成了相声的戏剧结构和叙述模式,奠定其开放性体制,从而建构了相声的艺术本体;捧哏和逗哏的语言厚薄有差、雅俗有异、奇正反转、节奏快慢有序,铸就了相声的美学风貌;捧逗艺术的形成是相声职业成熟的标志。经济要素、艺术要素和政治因素是推动捧逗关系演变的三大动力,使捧逗关系在失衡和平衡中沉浮动荡,对相声艺术造成重大影响。     

LHC上LRTH模型中Ztt和ZTt产生过程的研究

首先计算了左右双Higgs(LRTH)模型中大型强子对撞机上Ztt的产生截面及其相对修正,结果发现在LRTH模型所允许的参数空间内,Ztt的产生截面有较大的相对修正.然后,又计算了LRTH模型中新的产生道ZTt,发现当破缺标度不是很高时该过程有较大的产生截面.通过对以上两个过程的研究,可为检验LRTH模型提供很好的理论依据.     

相声艺术的捧逗与其文体

作为中国喜剧艺术的典型代表,相声从根本上说是一种兼具叙述体和戏剧体的“兼体性艺术”.捧哏和逗哏手法的特色凸显了相声艺术的兼体性本体：首先,捧逗手法决定了相声叙事的方式、技法和节奏,奠定了相声叙事的基本模式.其次,捧哏者和逗哏者分饰智者与愚者、文人与小市民,是相声中的基本角色,相互间的攻守形成相声表演的主要内容.总之,捧逗手法决定了相声的叙事和表演模式,造就了相声艺术的兼体性风貌.     

Dissipative Control of the State Delayed Systems

1　 IntroductionSince the notion of dissipative system was introduced by Willems ( 1 972 a) [1 ] ,andsubsequently generalized by Hill and Moylan( 1 980 ) [2 ] ,it has played an important role insystems,circuits,and control.Dissipativeness is a generalization of the concept ofpassivity in electrical network and otherdynamical systems which dissipate energy in someabstract sense.Applications of dissipativeness in the stability analysis of linear systemswith certain nonlinear feedback were first…     

Framework for dissection of complex cytonuclear epistasis by a two-dimensional genome scan

Epistasis between cytoplasmic and nuclear genes is the primary genetic component of complex quantitative traits.Genetic dissection of cytonuclear epistasis is fundamentally important to understand the genetic architecture of complex traits.In this study,a two-dimensional genome scan strategy was employed to evaluate the contribution of cytoplasm,quantitative trait loci (QTL),QTL×QTL interactions and QTL×QTL×cytoplasm interactions to the phenotypic variation.The p-value and parameter value for each genetic effect were calculated by multiple regression analysis.A stepwise approach was suggested to build confidence in candidate QTL on the basis of q-value estimation,false discovery rate calculation and Bonferroni adjustment.A fine-scale grid scan strategy was proposed for further analysis of peaks of interest.Plant height in maize was used as an example to illustrate the efficiency of the two-dimensional genome scan strategy.     

对依法治校与现代大学制度的一种理论追寻

我国现代大学制度的内涵首先表现在应秉承学术自由、大学自治、以人为本和彰显民族特色的价值理念,要使得这些理念得以制度化就必须实施依法治校的方略;依法治校的实质内涵与灵魂是奉行法的统治,坚持一种制度化、规范化与程序化的大学治理方式;依法治校与现代大学制度之间存在着必然的逻辑贯通.     

A perturbation-incremental scheme for studying Hopf bifurcation in delayed differential systems

A new method,called perturbation-incremental scheme (PIS),is presented to investigate the periodic solution derived from Hopf bifurcation due to time delay in a system of first-order delayed differential equations.The method is summarized as three steps,namely linear analysis at critical value,perturbation and increment for continuation.The PIS can bypass and avoid the tedious calculation of the center manifold reduction (CMR) and normal form.Meanwhile,the PIS not only inherits the advantages of the method ...

中国北方城市道路横断面的生态设计

为了应对北方城市水资源的短缺和水环境的恶化,从水的自然循环角度,提出了一种城市道路的横断面。该设计在保持城市道路原有交通、排水用途的同时,增加了雨水对地下水的生态补给功能,把传统城市道路的单一排水系统提升为城市道路雨水渗蓄排综合系统。给出了可以在实际工程中应用的道路横断面形式以及增加道路渗水能力的有效方法;并就雨水对路基稳定性的不利影响,提出了相应的工程措施。该种城市道路的生态设计,技术简单可行、便于施工、附加成本低,适用于多种形式的既有及新建道路。
