New ESR-Electrochemical Cell Designs for Coaxial Microwave Cavity

本文报道了一种适用于同轴微波腔的新型ＥＳＲ—电化学池的设计。工作电极的长度可调节，部分屏蔽微波辐射的功能由上下两个屏蔽套承担。除了传统的螺线管，工作电极还可由打孔的金属筒、金属网、甚至复合材料制成。对电极可根据需要置于共振腔的外面或里面。总之，新设计灵活实用，适合更多的研究场合。本文列举了一些应用实例。

Schwarz混乱松弛法(S-COR)及同步和异步并行算法

早在1985年,[1]就把Schwarz交替法推广到任意多个子区域分解情形,并且提出了带松弛因子ω的S-COR算法.就一般的二阶自共轭椭圆问题而言,[1]断言:当ω∈(0,2)时,S-COR算法收敛,并在[1]和[2]中给出了收敛性证明.但在证明中有几处不严密的论证.本文利用Lions的理论给出一个收敛性证明,并提出几个同步和异步并行算法.其收敛性可由S-COR算法的收敛性导出.     

Synchronizing Complex Networks by an Adaptive Adjustment Mechanism

We propose an adaptive adjustment mechanism for synchronizing complex networks, in particular for sociological or/and biological systems. We do not take it for granted that a dynamical system is put on isolated nodes and they are coupled with each other by one （or more） variable（s）, as employed in most previous models. As a replacement, we suppose that each node may have any finite number of possible states, and their evolutions with time are determined by their nearest-neighbouring （or even second-nearest-neighbouring, etc） nodes in an adaptive adjustment mechanism. It is found that synchronization can be achieved for almost all connected networks and that the scale-free property can evidently improve the synchronizing speed.     

Chaos Synchronization Criterion and Its Optimizations for a Nonlinear Transducer System via Linear State Error Feedback Control

Global chaos synchronization of two identical nonlinear transducer systems is investigated via linear state error feedback control. The sufficient criterion for global chaos synchronization is derived firstly by the Gerschgorin disc theorem and the stability theory of linear time-varied systems. Then this sufficient criterion is further optimized in the sense of reducing the lower bounds of the coupling coefficients with two methods, one based on Gerschgorin disc theorem itself and the other based on Lyapunov direct method. Finally, two optimized criteria are compared theoretically.
