Starting from the necessity of constructing rational supply chain structure,conceptions of supply chain structure flexibility are expatiated.Then the connection between the supply chain structure flexibility and knowledge coupling among them are analyzed.On the basis of that,it constructs the model of knowledge coupling in the supply chain,and proposes supply...

从构建合理的供应链结构对供应链有效运作的必要性出发，首先阐述了供应链结构柔性的相关概念，接着分析了在知识经济时代，供应链结构柔性与成员间的知识联结关系，在此基础上，构建了供应链的知识联结关系模型，并从关系模型出发，提出了通过综合考虑知识联结范围和知识联结强度这两个知识联结的维度，来测度基于知识联结的供应链结构柔性，并通过实例说明模型的应用。

Chapter 4 firstly analyses the generation mechanics, calculating method and interference effect of flow force in the outflowing large-capacity proportional valve. Then it not only presents a structural design to compensate the flow force according to the performance characteristic of the cone valve, but also calculates and simulates the flow field at the valve port through CFD software Fluent6.0. At last it studies the influence of compensation structure parameters and obtains better projected dimensions.

微观还原论无法揭示物质涌现性的根源，以及物质结构与性质之间的相互关系，基于一般系统结构理论，建立了物质在原子，原子基团，分子和分子聚集体等层次上的统一的数学模型，即物质系统结构模型，通过对该模型的数学分析，研究了环境与物质结构，物质行为，物质状态之间的相互关系。

Since the reform and opening to the outside world in China, with the constant adjustment of ownership structure and production relation, China has experienced great changes of stratum structure and stratified differentiation, which brings complex impact on political participation mechanism, simultaneous, political participation affects the process of social stratum changes in a degree.

改革开放以来，随着所有制结构和生产关系的不断调整，我国社会阶层分化日益明显，阶层结构发生了重大的变迁。阶层结构的变化给我国的政治参与机制带来了十分复杂的影响，同时公民政治参与也在一定程度上影响阶层结构变迁的进程。

The two selection restrictions are determined by the cognitive function of middle construction. Though middles do not report actual event, they depict the properties of virtual events, therefore, naturally verbs in middles should be event verbs. And middles are cognitively motivated to deemphasize the role of agent in the occurrence of the event and focus the active role a passive participant could play in the occurrence of the event, then a volitional adjective or adverb that is under the control of agent would bring the deemphasized participant back into focus again, which is obviously contradictory to the cognitive motivation of middles.

这两种选择限制是由中动结构的认知功能决定的，中动结构虽然并不报道具体事件，但它描述虚拟事件的特性，因此动词必须是事件动词；同时中动结构之意图是弱化施事的作用而强化被动参与者在事件中的积极作用，因而一个语义上由施事自主控制的形容词或副词必然又会突显施事的作用，这与中动结构的认知动因是相矛盾的。

In order to investigate the divarication and chaos properties in nonlinear stage of complex structures deeply and reasonably, the mechanism and essence of the structure mechanics performance must be analyzed.

复杂结构在非线性阶段的行为一般呈现出分叉特性与不稳定特性，为了深入地从机理上了解和认识产生这种现象的本质原因，从而更合理、客观地进行结构非线性力学性能的分析，揭示结构的宏观损伤演化规律，有必要进行随机结构非线性分析方法的研究。

The results show that the microscopical pore structure of the three dimensional orthogonal woven carbon fabric structure perform is composed of body-centered cubes which arranged periodically at spaces. The net structure and shape of the pores of perform are determined by the size and proration of the fasciculus diameter, which are key factors influencing the gaseous permeability and final density of composites. Once the proration of the fasciculus diameters of different directions is determined, the trend of diversification of the permeability followed by pore rate during CVI process and the density of composites are stated, and the permeability increases with the increase of the fasciculus diameter.

研究结果表明：三维正交结构炭纤维预制体的宏观孔隙结构在空间上可以看成是由呈周期性排列的体心立方"晶胞"构成； X ， Y 和 Z 3个方向纤维束直径大小及比例关系决定三维正交结构炭纤维预制体宏观孔隙网络的结构和形状，也是决定反应气体在孔隙中的比渗透率和复合材料最终致密度的重要因素；当 X ， Y 和 Z 3个方向纤维束直径的比例关系一定时，不同预制体在CVI增密过程中比渗透率随孔隙率变化的趋势相同；复合材料的最终致密度一定；比渗透率随纤维束直径增大而略有增大。
