研究了金刚石／银复合材料的导热率与金刚石的含量、粒度等之间的关系,着重讨论了界面热阻对复合材料导热率的影响。并阐述了金刚石表面镀钛,能有效改善金刚石对银的润湿性,降低界面热阻,从而提高金刚石／银复合材料的导热率。     

简析蒋介石围追堵截红军长征失败的内因

蒋介石围追堵截红军长征失败的内因主要有:“攘外必先安内”的反动政策导致了蒋介石政治上的孤立;在围追堵截红军长征经过的十几个省份,蒋介石执行了许多与民为敌的政策,直接激起了沿途各省民众的反抗;蒋介石排除异己,欲借红军之力消灭沿途各省地方军阀的“一箭双雕”的部署,使国民党军队内耗严重,贻误了战机;蒋介石非常轻视红军的作战能力,在战略战术方面又显得因循、呆板;此外,国民党军队士气低落,缺乏战斗力也是围追堵截失败的又一原因。     

Optimum simple step-stress accelerated life tests for weibull distribution and type I censoring

This article presents an optimum simple step-stress accelerated life test for the Weibull distribution under Type I censoring. It is assumed that a log-linear relationship exists between the Weibull scale parameter and the (possibly transformed) stress and that a certain cumulative exposure model for the effect of changing stress holds. The optimum plan—low stress and stress change time—is obtained, which minimizes the asymptotic variance of the maximum likelihood estimator of a stated percentile at design stress. For selected values of the design parameters, nomographs useful for finding the optimum plan are given, and the effects of errors in preestimates of the parameters are investigated. As an alternative to the simple step-stress test, a three-level compromise plan is proposed, and its performance is studied and compared with that of the optimum simple step-stress test. © 1993 John Wiley & Sons.

An economic sequential screening procedure for limited failure populations

An economic sequential screening procedure is considered for limited failure populations in which defective items fail soon after they are put in operation and nondefective ones never fail during the technical life of the items. A cost model is constructed that involves screening test cost and external failure cost. A sequential scheme that minimizes the expected cost is derived from the solution of a dynamic programming formulation and the optimal decision at each stage is obtained in a closed form. © 1994 John Wiley & Sons, Inc.     

Economic screening procedures using a correlated variable with multidecision alternatives

Economic screening procedures using a correlated variable are developed for selecting markets in situations when there are several markets with different profit/ cost structures. It is assumed that the performance variable and the screening variable are jointly normally distributed. Profit models are constructed which involve three profit/cost components: profit from a conforming item, cost from an accepted nonconforming item, and screening inspection cost. Methods of finding the optimal screening procedures are presented and numerical examples are given.

线控灭雷具在流中接近目标的最佳路线及总体设计方案的选择

多数设计者倾向于将动力源置于线控灭雷具上的方案,以减小控制电缆在水中的阻力,提高灭雷具在流中工作能力。由于能源有限,灭雷具每次下潜的工作时间将受到限制。如何在有限的时间内提高灭雷具完成任务的能力,是摆在我们面前的重要课题。本文所要研究的仅是其中之一,即寻求灭雷具接近目标的最佳路线以求所消耗的时间最短,能耗最小,并从这点出发提出对总体设计方案的要求。
