First, For the coronary artery stent, two kinds of loads, including the pressure named 〓 derivatively from the balloon and the counterforce named 〓 on the wall edge of the stent, have been taken into account in the analysis of the stent.〓 and 〓 were changing as the stent expanding. So, the expansion process of the stent could be considered as the process composing of many extremely short equilibrium processes, where 〓 and 〓 could be regarded as constants and the stresses, the strains and the displacements were obtained using NFEA in every processes. Then, the stresses, the strains and the displacements obtained in every processes or steps were added up to get the final structure of the coronary stent.

首先,解决了支架有限元分析的载荷非线性问题,认为医用心血管支架受到两种载荷的作用:球囊直接传递的压力〓和球囊对不锈钢支架丝壁边缘的反作用力〓,这两种载荷在支架分析中必须都考虑进去;〓为非线性载荷,随着支架扩张不断变化,处理时将支架扩张的整个过程看成由37个很短的平衡过程组成,在每个过程中取〓为常量,采用有限元法获得应力、应变、位移,最后将各过程的应力、应变、位移迭加起来就获得了不锈钢支架总的应力、应变和位移;本研究用变分法和有限元法模拟杆件拉伸证明了上述方法是合理的。

In the last chapter, on the basis of theories in paper [4, 5], the notions of strong mixing, weak mixing, generator and expansion of the variable-parametric dynamical system are introduced, it turns out that in variable-parametric dynamical system strong mixing implies weak mixing and then implies transitivity; it is proved that if and both are variable-parametric dynamical system, F conjugates with G , the members of F are communicate with each other and the members of G are also communicate with each other, what's more, they are both homeomorphism, then F is strong mixing implies G has the same properties; futhermore, we prove that F is strong mixing implies F Devaney chaos in the sense of modification in variable-parametric dynamical system and that F Devaney chaos in the sense of modification if and only if G Devaney chaos in the sense of modification when semi-conjugate with and they both are communicate and homeomorphism; at last, we illustrate that F has generator if and only if it has weak generator, and we also prove that if F is expansion, then F has generator.

在第三章中,我们在文[4,5]的基础上,提出了变参数动力系统拓扑强混合、拓扑弱混合以及变参数动力系统的生成子、扩张的概念;证明了变参数动力系统拓扑强混合蕴含拓扑弱混合,进而蕴含拓扑传递;证明了:如果,为两个变参数动力系统,F与G拓扑半共轭,且F两两可交换,G两两可交换,它们均为同胚映射,那么F拓扑强混合,则G也有同样的性质;本章还证明了变参数动力系统拓扑强混合蕴含F在修改的意义下Devaney混沌;在此基础上得出了:如果变参数动力系统与变参数动力系统拓扑半共轭,它们都两两可交换,并且它们均为同胚映射,那么F在修改的意义下Devaney混沌当且仅当G在修改的意义下Devaney混沌;得出了F有生成子当且仅当F有弱生成子;如果F是扩张的,则F有生成子。

To achieve these goals, the following actions must be taken.First,the vertical and horizontal connection of city planning must be strengthened;balance be made between market system and local governments in allocating materials;cooperating systems between city governments be intensified;in order to guarantee the balance between internal structures of urban systems.Second,the stability of agricultural production and provisionment must be guaranteed;rural integration be accelerated;system of land transfer be reformed;rural citizens be given equal status in participating urban development and sharing the fruit of urban development;in order to guarantee the balance between rural and urban development.Third,supervision of upper governments must be strengthened;the "personal rationality" of local governments(the choice of short-term benefits for local area) be restrained and local governments be stimulated to bring into play "collective rationality"; scientific development patterns in active improvement of urban quality and steady enlargement of urban size be insisted;in order to guarantee the balance between urban and economic development,and the balance between improvement of urban quality and enlargement of urban size.Last but not the least,considering the crucial status of urban social development in deciding the socialist direction of urbanization of our country,it\'s essential that social development be made a political responsibility of local governments in order to guarantee the balance between the social and economic development of cities.

为此,应当加强城市规划的纵向与横向衔接,平衡市场机制与地方政府这两只手的资源配置功能,强化地方政府问的合作机制,确保城市体系内在结构的均衡;保证农业生产稳定与粮食供应,加快农村整合,改革土地流转制度,确立农民参与城镇发展的平等地位,合理分享城镇发展成果,实施拖腿扩门并举战略,确保农村发展与城镇发展的均衡;加强上级政府监管,抑制各级地方政府的&个人理性&,促使其更多地发挥出&集体理性&,坚持积极提升城市质量、稳妥扩张城市规模的科学发展模式,确保城市发展与经济发展、城市质量提升与规模扩张的均衡;城市社会发展事关我国城镇化的社会主义方向,要把社会发展作为地方政府无可旁贷的政治责任,才能确保城市社会发展与经济发展的均衡。
