影响油罐电位的输油参数分析

目前,油库、储运公司改扩建工程较多,不可避免对工艺流程进行调整,依据液体静电产生原理,应用高斯定理和欧姆定律等理论,分析油罐注油过程中油面电位以及时间与管径、流速等各参数之间的关系,针对管径不变流速变化的情况,进行实验分析,在不对管路进行整改,仅对泵进行重新设计优选时,对如何控制罐内电位的安全,提出参考方案,对油库改扩建工程有一定的指导意义。     

System availability in a gamma alternating renewal process

We measure the effectiveness of a repairable system by the proportion of time the system is on, where on-time and off-times are assumed independent and both gamma-distributed. This measure is helpful for system planning and control in the short term, before the steady-state is reached, and its mean value is intermediary between instantaneous and steady-state availabilities. We also present other significant results concerning the Gamma Alternating Renewal Process. © 1999 John Wiley & Sons, Inc. Naval Research Logistics 46: 822–844, 1999     

The NBUL class of life distribution and replacement policy comparisons

Let X and X_τ denote the lifetime and the residual life at age τ of a system, respectively. X is said to be a NBUL random variable if X_τ is smaller than X in Laplace order, i.e., X_τ ≤_L X. We obtain some characterizations for this class of life distribution by means of the lifetime of a series system and the residual life at random time. We also discuss preservation properties for this class of life distribution under shock models. Finally, under the assumption that the lifetimes have the NBUL property, we make stochastic comparisons between some basic replacement policies. © 2001 John Wiley & Sons, Inc.

作为历史观念的《尚书》“先王”观念

"先王"观念与"法先王"思想基本为同一范畴。"先王"观念与古代中国宗法社会紧密相连,还与中国古人对"政治制度和社会文化的延续性"的深刻认识有关。《尚书》中尚未出现"法先王"一词,但是"先王"观念非常浓厚,是中国"法先王"思想的文献源头。"先王"观念也是历史观念的重要体现,它与"殷鉴"思想、"忧患"意识一起构成了《尚书》历史功用思想的整体,并对后世产生了很大影响。     

状态电子密度的数值反演

提出了一种计算状态电子密度的超分辨处理方法。这种方法是在Fourier变换的基础上,引入高频滤波器函数H（ω,α）,经滤波处理后,再取Fourier逆变换,得到近似解。此方法能够较好地抑制噪声干扰,且计算复杂性较低,文中给出了算法,证明了收敛性,最后给出了计算机实验结果。     

我国周边安全形势对边防工作的影响及应对策略

边防工作作为国防的重要组成部分,涉外性强,受周边安全形势影响大。当前,我国的边防工作既面·l盏着难得的发展机遇,同时更要直面各种挑战。分析周边安全环境对我国边防的影响,可以使我们更好地认清形势,趋利避害,抓住机遇,充分发挥职能作用,确保边防安全稳定。     

Defensive weapons and star wars: a supergame with optimal punishments

We model the perspective faced by nuclear powers involved in a supergame where nuclear deterrence is used to stabilise peace. This setting allows us to investigate the bearings of defensive weapons on the effectiveness of deterrence and peace stability, relying on one-shot optimal punishments. We find that the sustainability of peace is unaffected by defensive shields if the latter are symmetric across countries, while asymmetric endowments of such weapons have clear-cut destabilising consequences.     

2005～2009年《武警学院学报》文献计量分析

通过对2005～2009年《武警学院学报》5年间的载文、作者及引文情况进行统计分析,研究其载文量、栏目设置以及著者、发文地区和著者系统分布,并统计出合作度、合作类型、引文量、篇均引文数、引文语种及引文类型等,以期描述学报在改为月刊后的出版状况,从中发现一些带有规律性的问题,并客观评价其办刊特色,为刊物的进一步发展及相关学科动向提供理论依据。     

基于复杂网络的武器装备体系贡献度评估分析方法

根据结构决定功能的系统论观点,基于复杂网络理论对武器装备作战体系网络的拓扑结构进行了分析,构建了基于不确定性自信息量的武器装备作战体系作战效能分析模型,提出了计算武器装备体系贡献度的方法,并通过算例验证,探讨了网络结构演化及度量参数改变对武器装备体系贡献度的影响,为武器装备体系贡献度评估分析提供了技术支撑。     

武警学院教考分离的实践与探索

教考分离是武警学院近年来探索、实施的一种考试管理模式,主要通过制定教学管理规章制度、实行集体命题、试题库、试卷库、流水作业评阅试卷、试卷分析、成绩分析等予以实施,具有规范、科学、客观等优点。对实施过程中存在的一些问题,通过采用现代化技术设备、加强各项规章制度的实施等措施和手段予以改进和提高。
