The channel scale on transpiration cooling for the platelet thrust chamber of liquid propellant rocket engine is approaching micron dimension . it is very possible that micro - scale effects will occur in the flow and heat transfer of the channel . in the past , researchs on flow and heat transfer in the platelet micro - channel are mostly based on macro - scale theory 液体火箭发动机推力室壁面发汗冷却通道的尺度已达微米量级,通道内的流动与换热很可能存在微尺度效应,以前的相关研究都以宏观尺度的理论为依据,其研究结果的合理性需要进行微尺度效应的分析。
First , it is necessary to make the technical features of fdi clearly and definitely , the content include fdi ' s character , home country effect and new features . second , the law of the development of high - tech industry is studied ; based on all countries " experiment of developing high - tech industry , some basic features are abstracted ; at last , the fdi ' s home country - effect on the development of high - tech industry is studied deeply , the analyses including : scale effect , external effect and technical innovation effect 首先，评述了对外直接投资的理论成果，并阐述了对外直接投资的性质、母国效应和当前特征；其次，分析了高新技术产业发展的一般规律，在总结各国高新技术产业发展实践的基础上，抽象出若干特征；最后，深入分析对外直接投资对母国高新技术产业发展的影响，主要包括三个方面：一是规模经济效应；二是外部经济效应；三是技术创新效应。
To show the variety of pattern and process correctly , it is important to understand image objects scale effect in scaling courses , and to select the optimal scale for special class abstraction . based on methods and approaches in pixel - based image analysis , this thesis develops several results which focus on scaling and scale choose in object - oriented image analysis 每一个遥感专题应用任务对于影像分析中尺度的需求是不一样的，要正确反映测区内格局与过程的变化特征，了解多尺度转换过程中影像对象信息的变化效应，选择特定类别信息提取的最优尺度成为面向对象影像分析中关注的重点。
Chapter four makes some suggestions to china ' s future multinational operations . with china ' s entry into wto , chinese enterprises will face competition both at home and abroad . it requires joint efforts from governments and enterprises to implement " go - international " strategy : 1 ) to reform administrative mechanisms of governments and enterprises , 2 ) to fulfil scale effects by establishment of enterprise groups , 3 ) to increase international competitiveness by reasonable utilization of domestic and foreign resources , 4 ) to improve product design and promotion , 5 ) to set up explicit strategic goals in multinational investment , 6 ) to develop talents , 7 ) to enhance technology and develop integrative advantages , 8 ) to take flexible ways to enter foreign markets , 9 ) to implement diversification strategy 实施“走出去”战略需要政府和企业两方面的共同努力，中国企业跨国经营的发展首先是要改革政府管理体制和企业的经营机制，这是中国企业跨国经营发展的根本所在；同时要促进跨国企业的集团化以寻求规模效应；要善于发掘自身的技术和资源优势，实现内外资源合理配置，提高国际竞争力；要改进产品设计和宣传，突出产品差别优势；要有明确的跨国战略投资目标；要注意培养高素质的跨国经营人才；要提高科技水平，增强企业综合实力，而不能仅靠劳动力等方面的传统优势；在进入战略上也应因地制宜采取灵活多样的方式；同时要实施多元化的跨国经营战略。
Now the school has been developed into a school group with more than 10 , 000 students , and has cultivated a lot of senior skillful international talents for chengdu city , sichuan province and coastal regions , it has fully brought into play the scale effect and brand effect of vocational education group 目前，学校已发展成为拥有在校学历教育学生达万余人的办学集团，为成都市、四川省及沿海地区培养输送了大批高素质、精技能并与国际接轨的实用人才，充分发挥了职业教育集团的规模效应和品牌效应
The statistical methods include correlation analysis , regression analysis , etc . it draws the following conclusions : ( a ) the concentration of security brokerage is increased steadily if the trading commission floats , ( b ) the scale effect of security departments is obvious , ( c ) synthetic security companies did not gain the competitive advantage 竞争状态研究发现: ( 1 )浮动佣金制下经纪业务集中度稳步增加。 ( 2 )证券公司营业部规模效应明显。 ( 3 )综合类证券公司并未充分利用浮动佣金制度获得显著优势，还需在资源整合、业务优势互补等方面加大力度。
As a " intermediate institutional organizations " in the range of market and scientific organizations , industry cluster sets many relevance enterprises in a particular regional , its intrinsic association effect , the scale effect and the strive to improve mechanism , can effectively give the base the macroscopic benefit and the microscopic benefit 作为介于市场和科学组织之间的“中间性体制组织” ,产业集群集众多有关联性的企业于特定的区域,其内在的协效应、规模效应和自强化机制,能够有效地提高产业的宏观效益和微观效益。
According to the traditional rytov method , the theory model of modified rytov method is given for plane wave and spherical wave propagation in the atmospheric turbulence , and the characters of optical scintillation for waves propagation along horizontal paths is studied , the inner scale effect is considered , especially . then , the results , calculated by the modified rytov method , is compared with the experiment measurement , it shows that the modified method is suitable in moderate atmospheric turbulence 本文介绍了光波在湍流大气中传播的弱起伏和强起伏理论，从经典弱起伏理论出发，给出了光波在水平传输时的修正rytov方法理论模型，分析了在考虑湍流内尺度的影响下平面波和球面波入射时的闪烁特性，在中等湍流区计算结果与最近实验结果符合得较好。
This thesis , then beginning with the analysis of enterprises competition under network , demonstrates that risk increasing , external and internal cooperation changing and consumer scale effect are the typical characteristics of enterprises technological innovation process under network 论文随后以网络环境下企业竞争方式的转变为切入点，展开网络环境下企业技术创新过程的特性与机理研究。风险与不确定性加大、内外协作方式改变以及需求方效应突现成为网络环境下企业技术创新过程特性的集中体现。
But under the increasing competition background of the medical industry , tonghua medical industry begins to enter into the important period of transition in which the competing power of the market should be enhanced quickly . the conflicts that the degree of concentration of this industry is not high and the scale effect is unconspicuous appear step by step , and many enterprises for pharmacy fall across questions of lack in developmental stamina 但是,在医药行业竞争日益加剧的背景下,通化医药产业开始进入市场竞争力亟待提升的重要转折期,产业集中度不高、规模效应不明显的矛盾逐步显现,多数制药企业遇到发展后劲不足问题。
