The paper introduces the conception of digital home and its development and significance at first. Then it explains the foundation of digital home system platform based on hardware platform and system operation system. Following it talks about the frame hardware system design and the daughter module board of the embedded digital home system platform based on Blackfin. After that, it mainly explains the uClinux kernel's transplantation and realization on the digital home system platform. At last it introduces the embedded GUI—microwindow's transplantation and realization.

Show model combines growth model, math model and VR technologies to design the proper object structure of each organ of virtual plant. First of all,research background, research content of virtual plant area and Virtual Reality technology are introduced. The concept of VR and research content of virtual plant are defined. Secondly, we analyze math model of virtual plant, including Bezier curve, NURBS curved surface, fractal system, L-system and Catenary curve. Thirdly, we give show model of virtual plant in detail. Finally, the design of the platform and growth model on XML script is introduced , and how to show the virtual plant in the platfrom is discussed too.

本文首先介绍了虚拟植物领域的研究背景、研究内容和虚拟现实技术，明确了虚拟现实的概念和虚拟植物的研究范畴，然后介绍了虚拟植物器官的数学模型，对各个器官展开了拓扑结构分析，建立有针对性的数学模型，先后介绍了Bezier曲线，NURBS曲面，分形系统，L-系统和悬链线曲线，接着详细分类介绍了虚拟植物器官的显示模型，最后介绍了虚拟作物平台的设计，平台中基于XML脚本的生长模型，以及虚拟作物在作物平台中的显示。

Considering the practice nature of platform regulation, this paper uses some city's regulation and operation for reference. Then, according to the frame of regulation, the blue print of xi'an international port park was drawn out.

物流园区信息平台的规划是实践性很强的一项工作，本文对国内相关物流信息平台的规划进行了比较，并分析了一些已投入运作的物流园区信息平台，以此作为对实际规划的经验借鉴。

Be, let a website form the ecosystem that develops oneself, if be his completely,adding that is much tiredder, employ a person namely that cost also is not little, let thousand the user of about a hundred is updated not instinctively, will make those preceding part of the text what I mention is infinite, that should be how a thing of save worry, want now which familiar website is not in that way ah, quite a few board piece it is to rely on broad him person that browse to prop up rise, the website is exacter ground function no more than is a platform only just, guest of rich of a few spaces is the platform that knowledge shares the confabulate that make friend, website of business affairs of a few electrons is the platform that buys the home to sell the home to trade.

是啊，让网站形成自发展的生态系统，如果全是自己添加那是多累呀，就是雇人那成本也是不少呀，让成千上百的用户不直觉地来更新、来做那些上文我提到的无限，那该是多么省心的一件事，想想现在哪个熟悉的网站不是那样呀，相当多的板块都是靠广大的浏览者自己支撑起来，网站更确切地功能无非就只是一个平台而已，一些空间博客是知识共享交友谈心的平台，一些电子商务网站是买家卖家交易的平台。

To these two types of BFP, the new schemes of towing and submergence were put forward: Type A BFP, added buoyancy with detachable cone-shaped pontoons, can be towed directly, and the self-ballast mooring submergence method can be applied into its submergence process. Type B BFP can be towed with the tied pontoons, and the submergence method is davit launch.
