拓扑分子格的弱分离公理

本文是文［１］的继续，我们以Ｑ－远域为工具，首先引入和研究了拓扑分子格的ＳＴｉ分离公理（ｉ＝－１，０，１，２，３，４）。其次我们引入了Ｓ－不定序同态和Ｓ－同胚序同态等概念，给出了它们的若干特征性质。最后我们得到了各种ＳＴｉ分离公理是Ｓ－同胚序同态下保持不变的性质。     

水电工程规划设计方案的自动生成及评价

本文介绍了在水电工程规划设计时，如何利用三次自然样条插值函数在有限个方案的基础上自动生成无限多个方案，然后采用多目标综合决策模型在其中选择最优方案的一种方法．文中还给出了程序流程，并以某水电站正常蓄水位选择作为实例，对方法进行了验证，结果与专家决策完全吻合．     

Ruin Probability with Variable Premium Rate and Disturbed by Diffusion in a Markovian Environment

We consider a risk model with a premium rate which varies with the level of free reserves. In this model, the occurrence of claims is described by a Cox process with Markov intensity process, and the influence of stochastic factors is considered by adding a diffusion process. The integro-differential equation for the ruin probability is derived by a infinitesimal method.     

中国书法的民族文化精神

中国书法作为中国文化的核心和精髓，突出地表现在五个方面：一、生生不息的传承精神；二、自由成己的创造精神；三、天人合一的理性精神；四、博大坚毅的人格力量；五、艺术化的人生态度。这些颇具民族性的特点，值得后人认真总结和发扬光大。     

STABILITY CRITERIA FOR A CLASS OF UNCERTAINSYSTEMS WITH TIME—DELAY

Some stability criteria are obtained for a class of uncertain systems with time-delay usingLyapunov functional and analytic techniques. It is easy to check the criteria by making use of theboundedness of the uncertainties.

Technical Notes ：STUDIES ON THE VALUE OF SECONDARY MARKET TO THE SUPPLY CHAIN

This paper investigates the impact of a secondary market, where retailers can buy and sell excessinventories, on the supply chain. We develop a two-period model with a single manufacturer and tworetailers. At the beginning of the first period the retailers order and receive products from themanufacturer, but at the beginning of the second period, they can trade surplus products betweenthemselves in the secondary market. We investigate the impact of the correlated dependence ofretailers' demand on both the quantity effect and the allocation effect under the secondary market.Lastly,we study potential strategies for the manufacturer to increase sales with the existence of thesecondary market.
