Collaborative virtual battlefield discussion enviroment is the extent and development of traditional Collaborative virtual enviroment, integrates cyber-cooperation, virtaul reality, internet-based 3D visualization, media streaming, becomes a new method of military automated command system ensurer under high tech condition. This paper reseaches the theory and realization techniques of Collaborative virtual battlefield discussion enviroment deeply based on enough understand of Collaborative virtual enviroment theory, and explores a prototype sysytem.

协同虚拟战场研讨环境是对传统协同虚拟环境的延伸和发展，它是对计算机协同、虚拟现实、网络三维可视化、流媒体等多种技术的集成，是高技术条件下军队指挥自动化保障的一种新方法；本文在充分了解协同虚拟环境及其相关理论的基础上，对协同虚拟战场研讨环境的理论和实现技术做了较为深入的研究和探索，并开发出了原型系统。

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。

In the future,network virtual community become more and more variously , more and more like reality.even better than reality for its excitiment and amusement.what realty have exist in fictity.what can not realise in realty is easy to do in fictity.you can marrige with your lover,you do business with your cooperation,you can speculation on stocks,you can make friends,you can do every thing you want unless some thing not allowed in law,which make the bound become more and more fuzzy betwen fictity and reality.people will mist easily between them for a long time.it is scareful to face such blurred phenomenon.so for those who have not enough ability to distinguish ,especiely youth and children,it is easy to lost themselves.

不久的将来网络虚拟社区会越来越全面。跟现实几乎一模一样，甚至比现实的东西还要全面刺激。现实中有的虚拟空间里都有，现实中无法实现的可以在社区里得到满足和实现。可以在虚拟社区里结婚生子，做生意，炒股票，交朋友等等。这样虚拟和现实的界限会越来越模糊，时间久了人们就会在两者之间迷离了，形成虚拟和现实的交错现象。有时候想想也挺可怕的。所以对于没有做够判断和分辨能力的人来说，特别是青少年和儿童，真的容易迷失自己。

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.

首先计算2000年江西省主要农产品虚拟水含量和城乡居民生活消费虚拟水含量，得出粮食作物的虚拟水含量为284.81×108立方公尺；城镇居民人均消费主要产品的虚拟水量为768.27立方公尺；农村居民人均消费主要产品的虚拟水含量为670.17立方公尺。

Abstrict: This article aims at remedying the weakpoint in Virtual Reality Mining Technology, by combining VR Technology and Multimedia Technology with Database, introduced the whole course of setting up a system which based on the VRPlatform, which combining the virtual mine-visiting with data searching.

针对目前国内虚拟矿山技术存在的不足，将虚拟现实技术、多媒体技术同数据库结合起来，基于 VRPlatform 虚拟平台介绍了一套包括虚拟矿山漫游和数据查询与一体的虚拟矿山系统的创建过程。

Mariana VS virtual studio system is the combination of 3D virtual studio technology, 3D videotext and database technology, and is brand-new virtual studio that is made ingeniously. The system employs Mariana 3D rendering engine that was self-developed and high efficient. It can provide a strong platform of rendering for 3D virtual scene and 3D virtual videotext.

Mariana VS 虚拟演播系统是结合三维虚拟演播室技术、三维图文技术、数据库技术，精心打造的全新一代虚拟演播产品，该系统采用新奥特公司自主研发的强劲、高效的 Mariana 三维渲染引擎，为三维虚拟场景、三维虚拟图文应用提供功能强大的渲染平台。

The virtual design technology is an advanced product developing technique in 21 century.and it is effective on developing sugarcane harvester as soon as possible.however, there is no research report about the virtual design technique used in the development of sugarcane harvester at present.ln the dissertation.the visual virtual design method was used to provide support for sugarcane harvester development.ln the chapter twojt expatiates X3D practical application in the virtual design platform for sugarcane harvester.in this section,it brings forward XML normal transport format in virtual design platform for sugarcane harvester.

虚拟设计技术是21世纪先进的产品开发技术，是快速研发丘陵地带甘蔗收获机械的有效手段。但是目前尚未见采用虚拟设计技术开发甘蔗收获机械的研究成果报道。本研究提出可视化虚拟设计技术进行甘蔗收获机械的研发，并围绕设计开发过程的若干关键技术进行分析研究。论文在第二章阐述了X3D技术在甘蔗虚拟设计平台中的实际应用，提出了XML作为虚拟设计平台的标准传输格式。
