First, we consider nonholonomic chained systems with modeling error, in this section,based on back-stepping , using the so-called adding a integrator , state-scaling technique , we design discontinuous feedback law,such that the trival solution of the closed-loop systems global strong stable; Second,we consider high-order nonholonomic chained systems with modeling errors and external disturbances, in this section,using input/state-scaling and integrator backstepping methods , we design discontinuous feedback law and give out the switching strategy, such that the closed-loop systems global /C-exponential stable; Finally, we consider a class of more general power chained form systems with particular drift-terms, in this section , using Lyapunov method, we design time-varying feedback law , such that the closed -loop systems p—exponential stable.

第一部分考虑的模型为带有模型误差的高阶非完整链系统，我们运用加幂积分器、State-scaling技巧以及基于Back-stepping方法构造出不连续反馈律，从而使得所讨论系统的闭环系统的平凡解全局强稳定；第二部分考虑的模型为带有模型误差的不确定高阶非完整链系统，这一部分我们运用input／state scaling和integrator backstepping方法构造出不连续反馈律，并给出切换策略，使得所对应的闭环系统全局κ-指数稳定；第三部分考虑的系统是形式更为一般的且带有特殊形式漂移项的幂链系统，利用Lyapunov函数方法，设计出时变反馈律，从而使得相应的闭环系统ρ-指数稳定。

Is such a simple and ordinary, but the so-called love at first sight hidden bar.

就是这样的简单平凡，却暗藏了所谓的一见钟情吧。

He lived in a haunted world where mundane facts, a reflection in a mud-puddle, an image chalked on a wall, the slant of a black-robed figure against mist, radiate significance at once familiar and only half-consciously grasped.

他生活在一个烦恼滋生的世界，有很平凡的现实，泥泞生活，白墙涂鸦，朦胧薄雾中黑色风衣的侧影。

I know I'm a common ignorant girl, and you a book-learned gentleman

我知道我只不过是个平凡的不学无术的丫头，而你是个有学问的上流绅士。

I know l'm common ignorant girl, and you a book-learned gentleman.

我知道我只不过是个平凡的不学无术的丫头，而你是个有学问的上流绅士。

Amidst the joyful ringing of Christmas bells, we ushers in a peaceful evening.

分享： 就是这样两句&平凡的&节庆套话，可译得多好啊！

Everyone of us was just as frail and common as a reed, but we won't change our mind of pursuing the happiness and beauty.

我们每个人，都脆弱平凡如一株芦苇，但内心对幸福和美好的向往，却是如此执着。

In Chapter 3, we use the sufficient and necessry conditions of minimal point being critical point on closed convex set and construct closed convex sets with some character as more as possible, to discuss the existence of solusion of nonlinear Hammerstein integral equations on different closed convex sets. We get the results of multiple solutions.

在第三章中，我们没有借助于条件，而是利用闭凸集上的极小值点是临界点的充要条件，构造出尽可能多的具有某些特性的闭凸集，在不同的闭凸集上讨论非线性Hammerstein型积分方程的非平凡解的存在性，从而得到多解性的结果。

Her gown was a light cotton print, and from the back of her head a kind of rope could be seen descending to some distance below her waist, like a Chinaman's queue.

虽然她们的外貌现在在一双平常的眼睛看来，显得肥胖臃肿、庸俗平凡，但是在她们自己看来却是全然不同的。

The grass seeks her crowd in the earth.

平凡的芳草求她地上的伴侣。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
