To aim at the differences in the ingredients which should be considered when different cooperative partners are chosen in virtual supply chain, the evaluation index system of upstream cooperative partner, downstream cooperative partner and logistics enterprise in networked virtual supply chain are established. Based on the differences of constructive technologies of traditional supply chain, the cooperative partner selection mode of networked virtual supply chain is established. The application of AHP in cooperative partner selection of virtual supply chain is researched. The dynamic construction mechanism of networked virtual supply chain is put forward to deal with all kinds of exceptions in the supply chain execution.

The first step, reduce the fictitious economy systematic risk of our country, analyze and prove from three respects concretely that the basic relation of fictitious economy and real economy, the system of fictitious economy, market mechanism: The main argument of basic relation of fictitious economy and real economy have:(1) Structural adjustment and optimization of real economy (2) Pay close attention to the balance of fictitious assets and physical assets of macro econo

虚拟经济体系方面的主要论点有：（1）完善虚拟经济体系的管理体制：建立健全虚拟经济法律法规体系，实现"依法治业"；建立健全虚拟经济监管职能体系；增强虚拟经济运行信息的透明度；（2）提高虚拟经济体系中虚拟资产的风险管理水平。市场因素方面来说，主要是：（1）实行灵活的汇率政策；（2）加强资本流动管理；（3）积极推进虚拟经济监管国际合作第二步，建立我国虚拟经济系统风险化解机制。在采取有效措施降低我国虚拟经济系统风险的基础上，还需要警惕来自市场方面虚拟经济风险冲击。我以为，对此有以下三种化解办法：（1）市场机制的基础调节；（2）法律和政策约束；（3）强行临时管制。论文创新点：建立了一个我国虚拟经济系统风险预警度量模型，并运用这个模型对我国虚拟经济风险的现状进行了评估。

The attitude that we hold to the fictitious capital development should be that: the development of the real economy is the kernel of Chinese economic development, we should satisfy the needs of the development of the real economy better through expanding the quantity and categories of the fictitious capital appropriately; we should pay attention to harmonizing the dialectical relation between fictitious capital and the real economy, so that we can make use of the positive effect of the fictitious capital to the real economy, and prevent the harm that may caused by fictitiousness and capital character of the fictitious capital.

我们对虚拟资本发展的态度：以实体经济的发展作为中国经济发展的核心，通过适度发展虚拟资本的种类和数量来更好地满足实体经济发展的需要；注意协调好虚拟资本与实体经济的辨证关系，发挥虚拟资本市场促进实体经济发展的积极作用，并始终警惕虚拟资本的虚拟性和资本性可能造成的危害。

It will expose the design problem of maintainability of civil airplane to the early stage of design. This paper discusses the composing of the virtual maintenance environment, builds non-immersion virtual maintenance environment of undercarriage, and establishes a part library management system. The characteristic of maintainability models and maintainability analysis based on virtual technique is researched to give the maintainability frame model of civil airplane virtual maintainability analysis. All levels of maintenance time model and maintenance man-hour model are established. Analog-Huffman code is proposed to optimize space partition method in traditional collision detection arithmetic."Maintenance therblig"is brought into the broken down of maintenance tasks, and the new maintenance tasks broken down method is proposed. The demands of human measure, position, and equipment layout in human engineering are discussed, and the verification methods of human measure, position and equipment layout in virtual maintenance are given. Basic principle and verification procedure of maintainability virtual verification is developed primarily, and the reachablity, the visibility, and posture-comfortability are verified.
