Compared with other gas discharge switches, such as gas spark gap, vacuum switch, hydrogen thyratron and ignitron, the parameters of PSS, such as hold-off voltage, peak current, rate of current rise, lifetime, time delay, jitter, have been greatly improved.

伪火花开关与其它气体放电开关如高气压火花间隙、真空开关、氢气闸流管及引燃管等相比，开关的各项参数如耐受电压、峰值电流、电流上升陡度、寿命、时延和抖动都有了较大改善。

Unfortunately,the surge protection devices are occasionally faulty because of the protection indeterminateness due to the design and installation of SPD.We discussed the random characteristic of lightning strike,the breakdown time delay and jitter of SPD,multi-stages protection blind zone,the reflection oscillation of lightning wave between loads and SPD's,and proved the indeterminateness o...

由于SPD设计和施工带有多方面的不确定性，使被保护系统可能出现故障，导致SPD保护失效，因此从雷击特性的随机性、组成SPD元器件的击穿时延和分散性、多级保护盲区、雷电波在负载与SPD之间的反射振荡特性等方面进行了分析探讨，最终得出了SPD保护不确定性的必然性。

Because of the universal existence of parameter perturbation and the fault ineluctability for actuator and sensor, it is more important and practical to study robust fault-tolerant control of parameter perturbation for linear system with time-delay.

由于参数扰动的广泛存在性以及执行器和传感器发生故障的不可避免性，使得研究具有参数不确定的时滞系统的鲁棒容错控制问题具有更重要的现实意义。

Our work on the problem of robust controller design for linear time-delay systems with nonlinear uncertain parameters are mainly concerned about thefollowing three aspects:Firstly, based on Lyapunov theory and using linear matrix inequation method, we put forward a plan to design the state feedback controller of the system with high structured uncertainty and matrix polytope structured uncertainty.

第三，在非结构不确定性假设下，基于系统的解和Bellman-Gronwall不等式，得出这类系统鲁棒稳定的充分条件。

However, the modified RWM is limited to homogeneous flow, and it assumes that the adsorption of hydrocarbon and the attachment of biomass are equilibrium and instantaneous. Moreover, there will be some numerical dispersion error, especially when the steps of space and time are injudiciously selected.

Delay等提出一种RWM的修正形式，它不必单个跟踪每个颗粒，而是将若干颗粒分别置于有限差分网格中集中、统一模拟，这样既可以处理颗粒数量较大的情况，又可以处理结合1阶反应动力学的情况，然而，修正的RWM只限于处理均匀流场及均衡假设下的质量交换和反应。

Secondly, in view of the identification problem after the change of MRAPC structure, the research has been extended to a kind of continuous system with time delay, and the robust convergence analysis for this model reference adaptive identification algorithm has been given. Using the intermediate value theorem in this analysis, the approximate problem in original analysis has been solved partly.

2针对MRAPC算法结构改变后产生的自适应辨识问题，考虑一种更一般的具有实零极点的时滞连续系统的模型参考自适应辨识算法，作者分析了该算法的鲁棒收敛性，在运用微分中值定理的基础上，解决了原有的收敛性分析中存在的近似问题。
