无理数e在电路基本理论中出现的物理意义

对无理数e在电路分析中出现的几个典型例子作了分析讨论，明确指出：由1／e决定的特征常数可以在时间分布上和空间分布上，把一个按指数规律非均匀变化的问题，用一个等效的均匀变化的问题来表示；可以反映初始变化率与最终稳定值之间的联系；可以更深刻地反映某些物理过程的本质特征。

密度分布非均匀的反馈控制Logistic单种群模型平衡态的稳定性

本文对种群密度在非均匀分布情形下,考虑了具反馈控制的滞后 Logistic 生态模型平衡位置的稳定性;分别给出了在常时滞和弱连续时滞以及强连续时滞情况下的稳定性条件;其结果是对 Gopalsamy 在密度均匀分布情形下相应结果的推广.     

Robustness to non-normality and autocorrelation of individuals control charts

This paper studies the effects of non-normality and autocorrelation on the performances of various individuals control charts for monitoring the process mean and/or variance. The traditional Shewhart X chart and moving range (MR) chart are investigated as well as several types of exponentially weighted moving average (EWMA) charts and combinations of control charts involving these EWMA charts. It is shown that the combination of the X and MR charts will not detect small and moderate parameter shifts as fast as combinations involving the EWMA charts, and that the performana of the X and MR charts is very sensitive to the normality assumption. It is also shown that certain combinations of EWMA charts can be designed to be robust to non-normality and very effective at detecting small and moderate shifts in the process mean and/or variance. Although autocorrelation can have a significant effect on the in-control performances of these combinations of EWMA charts, their relative out-of-control performances under independence are generally maintained for low to moderate levels of autocorrelation.     

The Veils of Clio: Dimensions of a Behavioral Narratology

This paper outlines a behavior-analysis approach to the field of narratology, the study of the narrative or story, with emphasis on nonfiction stories and the processes by which such stories distort the world they describe. Stories are described in terms of (a) a behavior-analysis adaptation of Todorov''s (1977) analysis of the plots of stories in terms of states of equilibrium/disequilibrium and (b) Grant''s (2005) analysis of the structure of stories in terms of establishing operations and escape contingencies. These two sets of concepts are applied to understanding how and why stories lead to distortions of the events they report.     

学术道路自述

回顾几十年来学术研究的道路,开始把鲁迅研究以专著形式系列化。这里的系列,只能说是“小系”,而不是“大系”。在这基础上,扩大研究领域,撰写关于中国现代小说研究,现代文学史研究的论著,同时进行散文创作,出版几本散文集。学术界的前辈、同辈、后辈的学者,在著作和文章中对我的论著、作品,进行热情的评论、分析,至感。     

散热器安装模式对采暖效果的影响

为了探究冷凝壁挂炉散热器的安装模式对采暖效果的影响,建立了散热器对流采暖的数学模型,利用CFD软件 SC/Tetra,采用湍流模型和稳态分析法,模拟了在实际工况下,不同安装模式的散热器达到稳态时温度场和速度场的分 布,并对数值模拟结果进行分析。结果表明：总功率相同的条件下,双散热器相比单个散热器,温度场和速度场更加均匀 平稳,舒适性较好;同侧安装方式比对称安装及对角线方向安装方式也更具有优越性,该研究为今后的工程应用提供理 论依据。     

《韩文考异》与朱熹的文法学研究

通过对韩文这个经典的校读,朱熹的文法学研究从对具体的字句篇章之法的分析、总结入手,集中发明了韩文文法“文从字顺”的一面,批驳了《韩集举正》的“好奇”,对于现实中流行的怪奇文风具有正本清源的意义,起到了正视听、导后学的作用,为当时及后代的文章写作灌输了平易、“稳当”的文法学思想,并进而建立起“文从字顺”的新文法标准。此外,朱熹所采取的文集校读的文法研究方式,在文法学研究史上具有开创性的意义。     

Testing monotonic equilibrium residual entropy of N-State Random Evolution

In this study, we propose an information measure of uncertainty associated with the random equilibrium residual lifetime of a system driven by N-State Random Evolution. A U-statistic test driven by a moment inequality is proposed for testing the hypothesis that the uncertainty of equilibrium remaining life of a system remains unchanged (when system is in the steady state) against the alternative situation when system’s equilibrium residual life has increasing uncertainty over time (i.e., the life distribution has Increasing Equilibrium Residual Entropy property). Some numerical results such as tabulated critical values and empirical power of the proposed test statistic are presented as well.     

文艺无定法

文艺无定法是文艺创造的一条基本原则，它具体表现在模仿生活、表现情感、刺激感官、躲避审美疲劳、追撵时代等方面。文艺无定法已经成为文艺保持生命活．力，获得大众接受的根本原因之一。
