In order to reduce the periodic current tracking error of the deadbeat control when compensating abruptly changing nonlinear load current, a repetitive controller is plugged into the deadbeat controller. Also, the repetitive controller can alleviate the parametric dependency of the deadbeat control and eliminate the effects on compensation performance caused by the uncertainties in the system.

另外，为了降低无差拍控制对系统参数的依赖型和系统中存在的不确定性对补偿性能的影响以及减小在补偿电流变化剧烈的非线性负载电流过程中存在的周期性的局部跟踪误差，本文在无差拍控制器的基础上，又提出了基于无差拍和重复控制的复合电流控制器。

By means of the undetermined coefficient method ,which is submitted in reference for solving nonlinear wave equations for their peaked soliton solutions ,three kinds of peaked soliton solutions are obtained for two important nonlinear wave equations— Korteweg-de Vries equation and Benjamin-Bona-Mahonyequation,respectively. One kind of peaked compacton solution ,which has the characteristics of both peaked soliton solution and compacton solution ,is obtained for above two equations with the aid of transformation relation between triangle function and hyperbolic function,. By use of above solutions, two kinds of periodic peaked traveling wave solutions are constructed.

FastNet takes DHRLM as routing model, it implements a diffluent multi-point distribution algorithm like Bittorrent, but FastNet is different from Bittorrent which is an unstructured P2P system, it implements the idea according to the characteristics of resource locating algorithm in structured P2P network. Moreover FastNet adopts periodic fault-tolerant algorithm to ensure active, quick and reliable distribution of security-related content.

FastNet以DHRLM为路由模型，实现了类似于Bittorrent的多点分流内容分发算法，与Bittorrent不同的是，FastNet在结构化的P2P网络中根据定位算法的特点实现了该算法：同时，FastNet采取了周期性的容错算法保证在P2P节点动态失效的情况下仍然能够主动、快速、可靠地分发安全内容。

It show that interstitial fluid pressure changes its sig n twice within one arteriolar vasomotion period and it is therefor not important that interstitial fluid pressure is a little higher or lower than atmospheric p ressure; arteriolar vasomotion can periodically result in lymph formation and in terstitial total pressure plays an important role in this procedure; local regu l ation of microcirculation can meet metabolic need to some extent in the form of dynamic equilibrium.

To more easily conceptualize and embody the learning in these stages of the cycle, they are set into a picture model of four cardinal, seasonal, and elemental directions, and an adaptation of Angeles Arrien's Forue-fold Path, and Ron Kurta' Sensitivity Cycle Barriers, as illustrated on the fold-out map at the beginning of each section of the book.

为了更容易地对这一循环中这些阶段的学习形成概念，并把这一学习过程具体化，我们插入了一个图片模型（这个模型是由四个主要的、周期性的基本方向组成的），及《Angeles Arrien's Forue-fold Path》的修订本和Ron Kurta的《灵敏度周期障碍》，如同这本书每一部分开始的插图一样。

The results show that the atomic population is time-independent provided that the atoms are in |β11〉 state. For the other three Bell states, there will appear the periodical collapse revival of atomic populationif the initial mean photon number reaches some special values. With the increase of the initial mean photon number, the oscillation frequency of the time-evolution of atomic population increases correspondingly, and the amplitude decreases. The degree of the entanglement of the two-mode entangled coherent field has no
