Because the theory of modular organization could explore the ambiguous views about collection organization such as networks , virtue organization , alliance organization , it makes the study focus on the micro - level of modular organization . and also because it could widen the range about research on the double coordination between market and firm , the theory of modular organization decrease the disadvantage of traditional theories 模块化组织理论不仅可以澄清长期困惑人们对诸如网络组织、虚拟企业、联盟组织等集合性组织概念模糊的认识,从而将研究对象更具体地聚焦在基本构成?模块化组织层面,而且,模块化组织理论还可以拓展对研究市场与企业渗透地带关于组织双重协调性的视野,弥补许多传统理论视角狭窄的不足。
According to the fluctuating property of wind , on the stochastic vibration finite element theory , some calculation formulas of the response , including the along - wind response and the across - wind response , are obtained , the ideology of the torsion vibration in the double - tower structure and the ideology of the double - tower structure ' s dynamical wind load are also put forward at the same time . by using the stochastic vibration module of the general finite element program , the paper analyses the performance of the wind resistance more deeply and fully , discussing the influence on the double - tower structure from the diversification of the different component . the variance law of dynamic displacement and wind - induced vibration coefficient is derived through analyzing structure stochastic vibration , so is the effect of several parameters on dynamic displacement , acceleration and wind - induced vibration coefficient 从结构风振的基本理论出发，通过对脉动风功率谱的分析，推导了结构风振响应(顺、横风向)的计算公式，同时提出了双塔结构的扭转振动和动力风荷载计算的思想，在结合通用有限元程序的随机振动模块的情况下，对双塔结构的抗风性能作了深入、全面研究，探讨了双塔结构构件截面的变化对其抗风性能的影响，同时探讨了顺风向风速谱的选取、风速、参与计算的振型数、风与结构耦合作用是否考虑等因素对分析结果的影响，比较了规范风振系数的计算与随机算法结构的异同，并讨论了原因，得出一些有意义的结论。
Based on the double principal - agency relationship in government investment which for the first time theoretically explains widely existing problems in government projects such as misuse of public funds , bad decision making and low execution quality , a new approach to government investment supervision in china is derived by combining chinese practices and advanced experiences of world bank , adb and many developed nations including germany , us , japan and uk 探索了政府投资领域中的双重监督管理模式，即公众对政府和政府对投资项目的监管模式。从自身的实践和发达国家、大型国际组织的先进经验出发，提出了建立我国现代化项目监督管理模式的新设想。 3 、本文对西方主要发达国家日本、德国、英国、美国等国在政府投资监督管理方面的法规、管理体制、监管模式、实际操作方法做了比较详尽地介绍。
In order to effectively use the vacant space beside the passenger train paths in the train running diagram of mixed passenger and freight lines and draw more freight train paths to improve the carrying capacity , the essay analyzes the reasonable drawing plan for freight train paths beside single passenger train arid two passenger trains respectively on the double tracked section with automatic blocking system according to the principle of minimal additional removal time and on the basis of the calculation method of removal coefficient table 摘要为了在客货共线运行图中有效利用旅客列车运行线两侧的空档，尽可能多地铺画货物列车运行线，以提高区段通过能力，在扣除系数表格计算法的基础上，按照附加扣除时间最少的原则，分析了在双线自动闭塞区段单列旅客列车和2列旅客列车两侧货物列车运行线的合理铺画方案。
First , it analyzes china ' s twice tax system reforms and current tax structure in brief , and suggests that china ' s tax structure should insist on the double - principal taxes system with income tax and turnover tax . second , it provides some suggestions of further perfection of china ' s tax structure . finally , it emphasizes that in china , it is of great meaning to improve tax collection and administration system for implementing the optimal tax system , especially income tax system 首先对我国税制结构的历史变革与现状进行了简要分析，针对我国现行税制商品税比重过高的现状，提出我国税制结构模式应继续坚持商品税和所得税并重的双主体税制；其次针对我国税制结构中所存在的问题，提出进一步优化的基本思路；最后重点强调了为保障税收制度的有效实施，我国在所得税制的改革中应加强税收征管的优化。
Due to the road width shortfall on section 4 of wufu road and west river road , this section is planned as a single track 3 . 14 kilometers long . this lrt line is planned to be mainly of the at - grade type , except for the area at the intersection of section 3 of chushan road and section 4 of kishon road , as well as on the north side of genko bridge over the love river , where underground sections are planned . there will be 23 stations on the double - rail sections and 9 stations on the single rail sections 并提出其轻轨系统优先发展路网，建议路线全长约9 . 6公里，设置9个车站，总成本以88年币值估算，约需新台币86亿，包括2 . 2公里高架，占全长之23 ， 2个高架站； 0 . 7公里地下，占全长之7 ， 1个地下车站；其馀6 . 7公里为平面型式，占全长之70 ， 6个地面车站。
