武器系统分析

系统工程与电子技术 1984年第3期 1-13页

作者： N.a.Kheir Y.S.sherif 王连成

人们通常是根据一个武器系统完成某项具体要求的军事能力对它进行审定,而对它能否完成其它任务不给予应有的考虑。本报告提出了进行武器系统分析的一种方法学,并且研究了与系统效用有关的各种准则和特征。这些准则和特征包括:系统性能... 详细信息

人们通常是根据一个武器系统完成某项具体要求的军事能力对它进行审定,而对它能否完成其它任务不给予应有的考虑。本报告提出了进行武器系统分析的一种方法学,并且研究了与系统效用有关的各种准则和特征。这些准则和特征包括:系统性能、战备状态、寿命周期费用、费用设计、可靠性、可用性、可维修性、可生产性、可操作性、能力、适当性、后勤等。本报告说明了一系列不同类型的适用于一般武器系统分析,特别是防空武器系统分析的仿真技术和语言,同时对其实用性、有效性和可靠性做了评价。除此之外,本报告还介绍了各种防空战略、技术与战术。

常规时移地震成像方法对监测对象开展重复观测,这种工作模式一方面比较耗时,工作量大,另一方面因数据采集时间间隔的不确定性对短期瞬态时移速度难以跟踪其变化规律。本文提出了Pa.simonious地震成像速度变化时移监测方法。其基本原理为:在地震测线离散采集几个炮集记录,采用地震干涉方法重构出密集的虚炮集数据,从而开展速度成像。通过试验场地内的连续1小时注水实验,采用该方法成功获得了地下水流动引起的地震速度变化,高精度成像了注水地下运移的分布规律。该方法的提出对于地下空间高分辨率成像以及地表关键带参数监测具有重要意义。

Objective： Over 50% of the world popula.ions a.e infected with Helicoba.ter pylori （H. pylori）. Most subjects a.e a.ymptoma.ic; however, in 1994, H. pylori ha. been ca.egorized a. group I ca.cinogen. The a.m of the study wa. to investiga.e the rela.ionship between H. pylori infection a.d ga.tric ca.cer. Methods： Thirty ga.tric ca.cer pa.ients （GCs） a.d 30 ga.tritis pa.ients were enrolled in the study. H. pylori wa. cultured on non-selective a.d selective media., infection density wa. a.sessed by qua.tita.ive culture. a.tibiotic sensitivity testing wa. performed. PCR wa. done for the H. pylori 16S rRNa.gene in a.dition to ca.a. va.a.a.d icea.genes. Results： H. pylori could be cultured from 100% of specimens obta.ned from a.l pa.ients. The density of H. pylori wa. higher in ca.cer ca.es tha. in ga.tritis pa.ients. The 16S rRNa.wa. detected in a.l GC pa.ients （100%） while it wa. only detected in 70% of ga.tritis pa.ients. The ca.a.gene wa. found in 53.3% vs 13.3% of GC a.d ga.tritis pa.ients, respectively. The va.a.gene wa. present in a.l GC pa.ients （by a. lea.t one of its a.leles） while it wa. only found in 33.3% of ga.tritis pa.ients. The va.a.slml combina.ion wa. the most predomina.t genotype in GC pa.ients, while m2 wa. the commonest a.lele in ga.tritis pa.ients （10%）. The icea.gene wa. found in 86.7% vs 40% of GC a.d ga.tritis pa.ients, respectively. Simulta.eous presence of multiple H. pyiori stra.ns wa. proved, both phenotypica.ly a.d genotypica.ly. Conclusion： The development of GC is linked to infection with H. pylori ha.boring certa.n virulence genes. Higher infection density of H. pylori wa. found in GC pa.ients. Co-existence of more tha. one stra.n of H. pylori in the sa.e pa.ient occurs in both ma.igna.t a.d benign lesions.

Trends Survey a.d identified 1094(27.4%)respondents(weighted popula.ion size = 21959672) without a.fa.ily history of ca.cer a.d 3138(72.6%) respondents(weighted popula.ion size = 58201479) with a.fa.ily history of ca.cer who were 50 yea.s a.d older.

We compa.ed complia.ce with CRC screening a.ong those with a.d without a.fa.ily member with a.history of ca.cer.
