The article is starting with since defining of bottom commercial space concept of skyscraper synthesis at first , on the basis of defining the skyscraper synthesis and bottom commercial space intension , do a concise exposition to the question appearing in the skyscraper synthesis and bottom commercial space developing history and development within the range of world and chinese on the senior level , and then sum up to summarize to the space and environment design of the bottom commercial space of skyscraper synthesis combine instance concrete , at last the development trend and designing inclining to be been analysed and prospect in the future to the bottom commercial space of the skyscraper synthesis 文章首先从高层综合体底部商业空间概念的界定入手，在明确高层建筑综合体及其底部商业空间内涵的基础上，对高层综合体及其底部商业空间在世界及中国范围内的发展历史及发展中出现的问题做一个简明的阐述，然后对高层综合体底部商业空间的空间及环境设计结合具体实例进行归纳总结，最后对高层综合体底部商业空间未来的发展趋势及设计倾向进行了分析及展望。
As a representative of this trend , the thesis selected the road intersection in the center of the city to solve the problem . firstly , spacial noumenon and nature has been definitized . secondly , from the " city " level , " road " level and " building " level , the thesis brings forward three principles for space such as " identifiable characteristic " , " directionality " , " integrated characteristic " , while summarizing the corresponding methods to realize 本文选取了这一趋势中具有代表性的城市中心区道路交叉口空间为着手点，明确了其空间概念及空间特性，分别从“城市”层面、 “道路”层面、 “建筑”层面三个不同的层次入手，提出了“可识别性” 、 “方向性” 、 “整体性”的设计原则，总结了各原则实现的手法。
In this way the author studied what the basic modeling elements of cmms , such as entity , action , task and interaction , shows to be in the conceptual model of c4isr communication networks . a series of specifications of conceptual model were established in unified modeling language ( uml ) in this paper , which can be used in constructing the formal conceptual model . the author also discussed how to perform the validation and verification of the conceptual model 论文通过任务空间概念模型( cmms )在c ~ 4isr通信网络中的具体应用，研究了cmms基本建模元素?实体、动作、任务和交互在c ~ 4isr通信网络概念模型中的具体表现形式，制定了利用统一建模语言( uml )进行形式化概念建模时的一系列概念模型描述规范，探讨了概念模型的验证与校核方法。
Thus , on the one hand , the technical advancement in computer and communication has raised people ' s ability of collecting , processing and distributing information , reduced the information cost , trade cost and transact cost in stock e xchange , which in turn shortened the time of making decision and execution in the financial transaction . the development of internet has redefined the concept of time and space . the stock markets in the world have been linked closely and vast capital flow easily between different countries and markets with " light speed " 在这种情况下，一方面，电脑和通信技术进步提高了信息的收集、处理和发布能力，降低了证券交易的信息成本、交易成本和清算交割成本，从而大大缩短了金融交易的决策和执行时间；互联网的兴起，重新界定了人们的时间和空间概念，全球各证券市场被紧密地连接起来，巨额资金以“光速”在各国和各个市场间快速流动。
