In the present work,the existence and uniqueness results aboutperiodic boundary value problems for different kinds of the nonlin-ear periodically perturbed nonconservative systems are establishedthrough the discretization technique,under suitable assumptions,by using global inverse function theorem and result about the ex-istence and uniqueness of periodic solution for nonhomogeneouslyfirst order linear periodic boundary value problem.

本文的第一章概述了在讨论原问题解的存在唯一性过程中以及构造和分析相关的数值求解方法时将要用到的全局反函数定理、有关矩阵特征值的若干重要引理、线性常微分方程非齐次周期问题解的存在唯一性定理和单参数影射方法及有关结论，并简单回顾了已有的证明非线性微分方程周期边值问题解的存在唯一性的方法，其中包括谱理论、最大最小化形式方法、摄动技术和全局反函数理论方法，最后，介绍了两类数值求解非线性微分方程问题的方法。

After the teeth often hard to eat baby food such as biscuits, toast, apple slice, carrot chip, etc., in order to exercise the masticatory muscles, and promote the development of teeth and jaws. Molars after 1-year-old after grow, it should be regularly stubby eat food such as vegetables, if eaten too soft fine food, lack of masticatory muscle training, jaw can not be fully developed, but the teeth are still growing, it will lead to crowded teeth, with irregular or facial deformities.

出牙后要常给婴儿吃些较硬的食物，如饼干、烤面包片、苹果片、胡萝卜片等等，以锻炼咀嚼肌，促进牙齿与颌骨的发育。1岁以后臼齿长出后，应当经常吃些粗硬的食物，如蔬菜等，如果仍吃过细过软的食物，咀嚼肌得不到锻炼，颌骨不能充分发育，但牙齿却仍然生长，就会导致牙齿拥挤，排列不齐或颜面畸形。

And if you keep your AV software up to date, you're most often covered anyway.

I sat next to the late John Peel, and we shared looks of amazement as the group went through the fully choreographed routines of a Motown act, providing a platform on which Jackson demonstrated every ounce of the gifts and the potential that would make him, by the end of the decade, the biggest attraction in the world of showbusiness, the star of stage shows of previously unimaginable lavishness.

我坐在已故的约翰皮尔旁边，在他们精心编排的汽车城例常曲目结束后，我们都非常看好他们将有惊人成就。汽车城给了杰克逊一个平台，将才华展示得淋漓尽致，也展示出了他的潜力——这些让他十年不到就成了全世界演艺届中最引人注目的明星，给予了大家以前无法想象的美妙表演。

As a result, during the famine years, the majority of poor farmers and carpenters, limner, a tailor, shoemaker, the carpet maker, hair Chengqunjiehuo tanner will go to Inner Mongolia to get to work to earn a living, in order to win,"extraoral" people's welcome, and some people and To beg on the show, some of the low paid, that's often said:"You-Ji Wan digging on the side line."

因此，每逢灾荒之年，广大贫苦农民和一些木匠、画匠、裁缝、鞋匠、毡匠、毛皮匠便成群结伙到内蒙去揽工谋生，为了博得"口外"人民欢迎，有的人又兼行乞卖艺，取得一些低微的报酬，即人们常说的："挖几碗莜面就行"。

Calculation method of flow force and linear model of differential pressure control system are established.

解析和使用伺服阀时，从喷嘴喷出到挡板上的气体流体力相对作用力较小，常被忽略。

Linear Fractional Transformation is adopted to translate the control of perturbation to the control of disturbance, then cost index is augmented, and with the min-max method, a robust receding horizon control law is derived. The sufficient conditions for the existence of the control law and closed-loop stability are also presented. The result is extended to time-invariant system with an infinite horizon, and its consistence with the robust control based on the concept of Quadratic Stability is verified.

首先利用线性分式变换，将摄动系统的鲁棒控制问题转化为对扰动系统的鲁棒控制问题；然后通过对性能指标的扩展，利用min-max方法，得到了鲁棒滚动时域控制律，并给出了其存在和使闭环系统渐近稳定的充分条件，并将结果扩展到对定常系统时域无穷的的情况，指出其与现有的基于二次型稳定概念提出的鲁棒控制的一致性。
