The human cartilages are composed of chondrocyte and extracellular matrix,the form of chondrocytes are hypertrophy and the quantity are less;the ECM of cartilage are compised of type II collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury,the ommilayer injury ofcartilage can be recovered by marrow,but because of without stimulation mechanism,the new tissues are merely fibrocartilages,they can not be coincide with hyaline cartilage in menchanics;the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation,thus,the plerosis of articular catilage can not depend on the proliferation of local chondrocyte.Ever since,people tried their best to find a way to reconstruct articular cartilage.

造成人体关节软骨损伤的原因主要为创伤和关节炎，关节软骨全层损伤可由于骨髓中间充质干细胞的高速增殖修复，但这种修复由于缺乏相应的刺激机制，只能形成纤维软骨，而不能形成符合关节生理、力学要求的透明软骨；单纯软骨部分损伤软骨组织内无血管，软骨细胞迁移迟缓，无法使损伤区域软骨细胞再生，因此，关节炎及关节创伤后的软骨修复不能依赖于软骨细胞的增殖和迁移。

The following exciting results are revealed: 1 When considering the influence of some nonlinear elements such as hard-limit of exciters, the effects of some devices such as Power System Stabilizer and Static Var Compensator which can introduce positive damping in power system, the reasonability of system parameter values in simulation, the SNB surface and HB surface on the boundary of SSSR will turn close to each other and even coalesce together; 2 Under some conditions, coupling between slow exciters and shunt capacitors will bring negative damping in power system dynamics, which increases the possibility of oscillatory instability. So the power system with mass shunt compensators is easily subjected to the oscillatory instability. In recent years, chaotic phenomena of power system have been reported many times. Some simulation studies even found chaos existing inside the power system SSSR. In this dissertation, chaotic phenomena in power systems are thoroughly studied in order to make clear the relation of chaos and SSSR. The following results are derived: 1 Based on Li-Yorke Theorem and their definition on the chaos, the existence of chaos in power system is verified; 2 Three possible routes of causing chaos in power system are found and deeply investigated. They are route of cascading period doubling, route of directly initial energizing and route of torus bifurcation (or quasi-periodicity). The latter two routes are investigated for the first time in power system stability studies; 3 When the stability conditions of chaos are broken, it is found they can lead to voltage collapse, angle divergence, or voltage collapse with angle divergence simultaneously.

针对在电力系统小扰动稳定区域内可能存在混沌吸引域的有关报道，本文深入研究了电力系统混沌现象的出现途径和与系统失稳模式之间的关系：1利用Li-Yorke定理和Li-Yorke的混沌定义，从理论上证明了电力系统混沌现象的存在性；2发现了电力系统中导致混沌出现的三种可能途径：倍周期分岔导致混沌、初始能量直接激发混沌和经由环面分岔导致混沌，并对后两种新发现的途径进行了较为细致的研究；3发现了混沌极限环破裂导致电压崩溃、角度失稳以及电压崩溃和角度失稳同时出现的现象，其中混沌极限环破裂导致系统角度失稳和电压崩溃及角度失稳同时出现的现象均属首次报道；4证明由微分-代数方程描述的系统模型，其小扰动稳定域的边界只包含HB、SNB和SIB三种分岔界面，在SSSR的内部和边界上，均不可能存在会导致混沌的点，从而将混沌现象排除在小扰动稳定域的研究之外，简化了后者的研究工作。
