The fierce competition in modern commercial society urges the economical organization re - examine on the traditional theories related to the organization structure and operation mechanism , and consistently carries corporation innovation to improve competing competence while pursuing scale and specialization 现代社会激烈的商业竞争迫使经济组织必须重新审视其组织结构及运行机制的传统理论,在追求规模化、专业化的同时,不断进行组织创新,以提高其竞争力。
The second one analyses the reasons , results and basic ways of modern business competition in detail based on the relative theories at home and abroad . it points out that china unicom must acquire the whole idea of competition in cdma market . meanwhile , it makes a further research into the critical factors 第二部分借用国内外商业竞争学术研究理论，全面分析商业竞争的成因、后果以及现代商业竞争的基本形式特征，指出在商战时代来临的今天，中国联通cdma在参与市场竞争时必须树立全面的商战观念，同时对中国联通商业竞争的关键环节进行了深入的研讨。
A topology of asymmetrical half bridge soft switching is researched in this thesis , which has inherent zero voltage switching ( zvs ) capability and thus potentially higher efficiency by its resonating of the leakage of power transformer with the parasitic capacitances of the power mosft switches , whereas it does n ' t raise the expense of the converter these studies in the thesis have been done as follows : ( 1 ) the topology of asymmetrical half bridge is introduced , and its principle and the relation of duty cycle and input voltage and output voltage discussed , the method of eliminating the deflection magnetism is also brought forward 虽然，软开关技术能够实现功率变换器的小型化、模块化等，但是，电路变得更加复杂，使得中小功率的变换器的成本增加，往往不利于商业竞争。本文研究了一种零电压的不对称半桥拓扑结构，它可以在不增加电路成本的基础上，利用电路自身的特点，实现软开关。本文所做的主要工作如下： ( 1 )对不对称半桥主电路工作原理进行分析，给出了占空比与输出电压、输入电压的关系以及消除变压器偏磁的方法。
Alternatively , sensitivity is higher in a monetary system in which the banks operate commercially in a highly competitive environment , requiring the efficient use of surplus interbank liquidity , than in a monetary system in which the bank management is not really accountable to the shareholders for its profitability 再假设另外两种安排，一是银行要面对激烈的商业竞争，因此必须有效地运用过剩的银行同业资金，另一是银行管理层无需就盈利向股东负责，相比之下前者涉及货币状况对结算结馀改变的敏感度较高。
Nowadays world economy is developing with the unresisting trend of integrated global market , digital business survival and internationalized business competition , which is represented by internet , knowledge - based economy and high and new technology with new economy seeing satisfaction of consumer ' s needs as cores 当今世界经济正以势不可挡的趋势朝着全球市场一体化、企业生存数字化、商业竞争国际化的方向发展，以互联网、知识经济、高新技术为代表，以满足消费者的需求为核心的新经济迅速发展。
The author makes a breakthrough with the " cooperation " . on the base of analyzing , the present situation of chinese city tv media , the thesis draws into the cooperation strategy from management , and has tried to open up the path for the development of the chinese city tv media from the angle of commercial strategy 笔者即以“合作”为突破口，在分析中国城市电视媒体发展现状的基础上，引入了管理学中的合作竞争战略，试图从商业竞争战略的角度，为中国城市电视媒体的发展寻求出一条新的路径。
About the three fundamental problems , in this paper , the author has constructed a research framework in which the theory of value chain , the theory of trade costs and the theory of business process reengineering are united , trying to combine the latest research achievements of net economy with the e - commerce application progenies and problems all over the world together , and systematically considering the challenges of e - commerce that we are facing . in this paper , the author has attempted to summarize the developing measures of e - commerce in traditional enterprise by applying the theory of marketing and business process reengineering in the view of combining the competitive strategies of traditional business with the features of e - commerce 论文紧紧围绕这三个基本问题，构建了一个以价值链理论、交易成本理论和业务流程再造理论为一体的研究框架，力求将最新的网络经济理论研究成果与目前国内外电子商务应用成果及问题结合起来，系统地思考我们所面临的电子商务的挑战；并尝试从传统商业竞争策略与电子商务特点相结合的角度，运用市场营销理论和业务流程再造理论，总结出传统企业的电子商务发展对策。
