两个含磷、氮化合物的EI-MS分析

采用气相色谱一质谱联用技术对二异丙氨基甲基膦酸乙基酯和N,N-双（2-甲基膦酸乙基酯乙基）甲基胺2个合成样品进行了分析,比较深入地研究了2个化合物的质谱裂解规律,并推断了样品中相关杂质的结构。     

A produce‐to‐stock system with advance demand information and secondary customers

We consider a manufacturer (i.e., a capacitated supplier) that produces to stock and has two classes of customers. The primary customer places orders at regular intervals of time for a random quantity, while the secondary customers request a single item at random times. At a predetermined time the manufacturer receives advance demand information regarding the order size of the primary customer. If the manufacturer is not able to fill the primary customer's demand, there is a penalty. On the other hand, serving the secondary customers results in additional profit; however, the manufacturer can refuse to serve the secondary customers in order to reserve inventory for the primary customer. We characterize the manufacturer's optimal production and stock reservation policies that maximize the manufacturer's discounted profit and the average profit per unit time. We show that these policies are threshold‐type policies, and these thresholds are monotone with respect to the primary customer's order size. Using a numerical study we provide insights into how the value of information is affected by the relative demand size of the primary and secondary customers. © 2007 Wiley Periodicals, Inc.

压水堆大破口失水事故安全装置实验研究

本文针对压水堆发生主管道“双端断裂”的大破口失水事故而提出了一种安全装置,对其工作原理及工程上实现的可能作了浅析,对其原理性实验过程及结果作了介绍。实验表明:这种安全装置结构简单,原理正确,工程上易实现,造价低廉。它在大破口失水事故发生初期(约数十毫秒)就能充分发挥其作用。对于防止堆芯熔化具有重要意义。

A replacement model with overhauls and repairs

This article generalizes the classical periodical replacement model with minimal repair by considering the effect of the overhaul, which is assumed to be able to rejuvenate the system. The generalization is based on the notion of the virtual age of a system introduced by Kijima, Morimura, and Suzuki [“Periodical Replacement Problem without Assuming Minimal Repair,” European Journal of Operational Research, 37 , 194–203 (1988)]. © 1995 John Wiley & Sons, Inc.     

渡江战役胜利对打赢信息化战争的启示

回顾渡江战役胜利历史,对打赢信息化战争提供了有益的启示:战争打的是利益,强敌干预皆必然;打赢信息化战争,必须站在国际政治格局的高度整体筹划.政治指引着军事,军事服务于政治;打赢信息化战争,必须围绕最高政治斗争的需要统筹考虑.战役之前细筹划,战斗实施巧变化;打赢信息化战争,必须采取机动灵活高效的战略战术.战役最后得胜利,人民群众是靠山;打赢信息化战争,必须创新人民战争的战略思想.
