浅论提高高校电子阅览室利用率的措施

分析了高校电子阅览室利用率低的原因，从加大宣传力度，加强电子信息资源的建设和管理，创建网络导航数据库，加强对读者的信息教育等方面提出了提高电子阅览室利用率的措施。     

化学问题解决的“信息加工”策略

本文借鉴现代认知心理学的某些观点，结合例证阐述了复杂化学问题解决的“信息加工”策略：信息简约、信息类比、信息引伸、信息转换、信息评价等等．     

具有完整性的控制系统设计方法

该文研究线性连续系统的容错控制问题，即设计反馈控制器，使闭环系统对可能的执行器失效具有完整性。该文利用代数方法，直接证明了期望的容错控制器的存在性，并导出了其解析表达式。最后，用数值例子说明这种方法的直接性与简单性。     

广义系统的某些性质

本文定义了广义系统的消失性,并给出了判别消失性的充要条件,进而给出了广义系统的闭环谱与其动态补偿器的谱不相交的充要条件.最后利用广义系统的一种特殊分解给出了广义系统脉冲可控的充要条件.     

节能气动系统数学模型的改进

作者曾提出一种节能近50%的节能气动系统,进行了理论与实验研究。本文重新定义特征时间 T_m~″和有效面积比 a_(?)~″,改进了它的退回阶段Ⅲ的动特性数学模型,使之能更准确地描述系统的真实特性,仿真结果与实验结果更趋一致。

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.
