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。

Influence of Additional Twist on Flax Cotton Blended Compact Yarn Property;2. By numerical integral of this model, the factors which affect the additional twist of yarn are analyzed, including the pressure in the profile tube and the coefficient of friction between the fiber band and lattice apron.

通过对集聚区内须条的集聚过程分析，建立须条变截面部分的力学模型，可以得出此部分须条是有附加捻度的，并且对影响这部分须条附加捻度的因素：须条与网格间的摩擦因数和负压的大小进行了分析，结果表明集聚区须条的附加捻度随着须条与网格间的摩擦因数和负压的增加而增加。

If, for example, Bill's will provided that Mary can live in his share of the house through her lifetime and then upon her death the house goes to Bill's children, Bill's share does not become relationship property if Mary enters a new relationship.

内镜下特征：呼气状态下会厌形态正常，而深吸气时会厌软弱卷曲，或过度后倾接触咽后壁，阻塞声门，部分病例伴有披裂粘膜水肿松弛。12例中8例行支撑喉镜下会厌部分切除术；另外4例施行会厌部分切除和改良悬雍垂腭咽成形术。

Results The anterior bundle of ulnar collateral ligament originates from the inferior aspect of the medial epicondyle and inserts immediately adjacent to the joint surface on the ulna near the sublimis tubercle. The posterior bundle originates from the medial epicondyle slightly posterior to its most inferior portion and inserts broadly on the olecranon process. The lateral collateral ligament arises from the inferior aspect of the lateral epicondyle. Two types of conjoined lateral collateral and annular ligamentous insertions on the ulna were observed. Type Ⅰ(61.2％) was bilobate and type Ⅱ(38.8％) was a single broad conjoined type with insertion on the ulna. The anterior band of anterior bundle was more tighten than the posterior band as the elbow flexed less than 60°. When the elbow flexed over 60°, the two parts of anterior bundle were equally tightened. The posterior bundle was tightened as the elbow was flexed more than 90°. The lateral collateral ligament was tightened gradually as the elbow moved in flexion.
