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.

Integration is widely used in all kinds of domanial management, and is the predominant contradiction, and is one of plain behavior of manager, all of these take the utility of information integration as precondition and conductor, information integration becomes the spontaneous or conscious behavior conducted by a spectrum, a group or an institution.

无论是客户关系、供应链管理、电子商务、还是人力资源管理、敏捷制造、企业应用集成等以及由此而衍生的其他的管理理念如虚拟组织、虚拟生产、虚拟团队、虚拟销售、战略联盟、虚拟管理、虚拟办公室、虚拟社区等无不是从整体、全局的角度来理解、认识资源、组织、生产、流通、消费、发展之间的关系，将信息作为精髓、作为指导，研究信息与其他要素之间的关系，研究信息在各类系统中的合理流动，借助信息的合理流动和利用进行资源的有效配置。

The study shows that the most striking feature about the use of the mandative subjunctive is that the distribution of the mandative subjunctive in MTE is much higher than that in MEE, NEC or T4, and much lower than that in LOBA or BROWNA. Another feature is that the morphological subjunctive, as one of the two variants of the mandative subjunctive, is most favored in MTE.

而在强制性虚拟语气中，原形式强制性虚拟语气在海事条约英语中的分布要高于迂回式强制性虚拟语气，而在其它语料库中，原形式强制性虚拟语气的分布却要低于迂回式强制性虚拟语气。

Firstly, virtual water contents were calculated for primary farm products and for virtual water consumption of residents in Jiangxi Province in 2000. The virtual water contents of crops was 284.81×108 m^3, and the virtual water consumption of rural residents 670.17 m^3. Then, based on the predecessors' study results, the difference of virtual water con- sumption of residents between Jiangxi Province and Shanxi Province was analyzed.
