燃料棒中铯活度比A(~(134)Cs)/A(~(137)Cs)的轴向分布测量与分析

在热室中 ,用γ扫描装置对秦山核电厂 3× 3 -2考验组件中辐照历史、燃耗及冷却时间不同的两根燃料棒中的铯活度比A(13 4 Cs) /A(13 7Cs)的轴向分布进行了测量 ,并利用自行开发的压水堆燃料棒破损特性分析程序FCAC进行了理论计算。结果表明 :辐照和停堆冷却过程中燃料棒中铯原子的轴向迁移可以忽略 ,燃料棒中铯活度比的轴向分布由燃耗的轴向分布决定。     

A Delay-Dependent Approach to Robust H ∞ Control for Uncertain Stochastic Systems with State and Input Delays

In this paper, the problem of delay-dependent robust H _∞ control for uncertain stochastic systems with state and input delays is investigated. The time delays are assumed to be bounded and time varying and the uncertainties are assumed to be norm bounded. By using the Lyapunov functional method, a new delay-dependent robust H _∞ control scheme is presented in terms of linear matrix inequalities (LMIs). Some numerical examples are given to illustrate the effectiveness of the proposed approach.

一种新型啮合式磁吸传动系统的电磁有限元分析

介绍一种新型的啮合式磁吸传动系统,它将电动机和减速机结合在一起,结构和制造工艺简单、传动比大、成本低、可靠性高。在分析其结构和工作原理的基础上,建立有限元分析模型,采用磁矢量势分析方法（MVP）对这种磁吸传动系统进行二维静态仿真,得到了系统的静态性能,并分析了磁势、工作气隙、材料等各种因素对该系统传动性能的影响。将计算结果与现有电机产品进行比较,得出该系统的优缺点。     

A study of Reduced-Rank stap

This paper starts with the discussion of the principle of Reduced-Rank (RR) Space-Time Adaptive Processing (STAP). It is followed by a dedication of the upper bound performance of all eigen-based RR methods provided by Cross Spectral Method (CSM) under the condition of a given processor rank and an identical secondary sample size. A performance comparison between two RR STAP processors with prefixed structure and CSM is performed by the means of simulations. It is shown that the performance of time pre-filtering followed by jointly localized STAP structure (i.e. 3DT-SAP) is very close to the upper bound and thereby it is an effective RR approach.
