The success of the transformation process depends on the existence of a supporting system that determines the process . experiences from abroad has demonstrated that venture capital system ( vcs ) is such an efficient supporting system that propels the marketization and industralization of hi - tech products 这一过程是否成功不仅依赖于高新技术成果本身的市场价值,而且依赖于客观上是否存在一个能对技术进步转化为生产力起决定性作用的支持系统。
( 2 ) the combination of vrml and java was used as main exploitation instrument in virtual reality system . two kinds extend mechanism of vrml scene were adopted to realize the function of browse and interaction . automatism roaming and interaction roaming were used in the scene ramble system also ( 2 )以vrml与java语言相结合作为系统的主要开发工具,利用vrml场景的两种扩展机制,实现了可供浏览的、实时交互的vcs虚拟校园系统场景,并采用自动漫游和交互漫游两种方式进行场景漫游。
Such two - period contract causes two agency problems , so we need three kinds of encouraging mechanism : to encourage vis to join venture capital funds ; to encourage vcs to invest enterprises properly , and to encourage ves to try their best in operating business . accordingly , we also need three kinds of controlling mechanism : how vis control vcs , how vcs control ves , and how ves control their employees 在两级委托代理关系下,风险投资需要三种激励机制:风险资本提供者需要激励去投资风险基金、风险投资家需要激励去投资创业企业、创业企业家需要激励去努力经营创业企业;相应地,风险投资也需要三种约束机制:投资者需要约束风险投资家、风险投资家需要约束创业企业家、创业企业家需要约束创业企业的员工。
The main contents of this research are the following : ( 1 ) the technology of graphic and image - based modeling and rendering is adopted , and 3d model of virtual campus system were accomplished . the geometry modeling of complex object is explored in vr , and commonly means were summed up such as trees , flower and grass etc . this paper also analyzed texture mapping problems of big and small geometry object , which can reduce workload of building scene ( 1 )采用图形与图像混合建模技术,实现了vcs虚拟校园系统的三维建模,并对虚拟世界中复杂物体建模技术进行了探索,总结出了树木、花草等复杂对象建模的一般方法,分析并解决了几何体的纹理映射问题,极大地减少了场景制作的工作量。
Main content of this paper is as follows : in chapter 1 we point out shortages of current relative researches , set up target and put forward the whole frames of this paper . in chapter 2 we analyze the three parties concerned in venture capital contract in china , namely vis , vcs and ves . from chapter 3 to chapter 5 we focus on fundraising stage of venture capital investment in china and discuss contract choosing , contract signing and contract implementing 本文研究的主要内容:第一章提出问题,指出现有研究的缺陷与不足,提出本文的研究思路及框架;第二章分析了中国风险投资契约的主体,即风险资本提供者、风险投资家及创业企业家;第三章到第五章分别论述融资阶段中国风险投资契约的选择、签订、履行;第六章到第八章分别论述投资阶段中国风险投资契约的选择、签订、履行;第九章总结全文。
The dissertation includes six chapters and the contents are as follow : in chapter 1 , the characteristic and the signification of vibration transducers are depicted , and the methods and theirs errors of calibration are presented detailed . then , the general situation of the development of vcs in domestic and abroad is introduced . the important signification of improving the performances of vcs is expounded 第一章叙述了振动传感器特点及其校准工作的目的和意义,重点介绍了传感器校准方法及其校准结果的误差分析,同时分析了目前国内外振动传感器校准系统的发展概况,阐述了改善振动传感器校准系统性能的重要意义,最后提出了论文的主要研究内容。
To deal with the echo information from doppler weather radar , in this paper we recommend the processing of some radar products ( cr , vcs , cappi , vil , wer , vwp ) , according to the research of nim on weather radar , referred to other advanced algorithm of radar products from home and abroad and combined with the requirement of application in our country . these products are produced on the platform of windows 98 or windows 2000 by the use of visual c + + 为了对多普勒天气雷达的回波信息(包括强度、径向速度和速度谱宽)进行加工、计算和处理,本文根据南京气象学院在天气雷达方面的长期研究积累,同时借鉴其他国内外先进的天气雷达产品的算法,结合我国气象业务应用的要求,对多普勒天气雷达的气象产品(组合反射率因子、任意垂直剖面、等高平面位置显示、垂直累积含水量、弱回波区显示、 vad垂直风廓线等)进行工程化设计。
This design for mvbc system adopts top - down eda common design flow . circuit design adopts veriloghdl coding description . function simulation and timing verification adopt simulation tool vcs of synopsys inc , the logic synthesis tool and fpga programming tool adopt the quartus ii of altera inc , and the fpga advice stratix ii ep2s15 该mvbc系统设计采用业界通用的自上而下的eda设计方法,电路逻辑实现采用veriloghdl硬件语言描述,功能和时序验证的动态仿真采用synopsys公司的vcs ,而逻辑综合与fpga实现采用altera公司的集成开发环境quartusii软件以及stratixiiep2s15的fpga器件。
Over the past few years china has removed some of its regulatory barriers to foreign investing , but a major hurdle remains for both overseas and home - grown vcs : they lack good " exit strategies " for cashing out their investments in chinese startups , such as selling shares in ipos on exchanges catering to high - tech investors 在过去几年里,中国取消了对外国投资的一些法规限制,但海外和国内风险投资面临的主要障碍仍然存在:它们缺乏可行的兑现在中国初创企业中的投资的"退出战略" ,如利用股票交易所面向高技术投资者的首次公开招股卖出股份。
In effect , the venture capital industry was downgraded from consisting of enterprises requiring special permits to the usual , and vcs no longer enjoyed incentives as in the past . moreover , the establishment of a vc firm no longer required prior approval by the ministry of finance but was instead directly licensed by the ministry of economic affairs department of commerce 2000年政府修订促进产业升级条例,同时废除创业投资事业管理规则,另颁创业投资事业范围与辅导办法,创投业则从特许事业转变为一般行业,不再享有租税优惠且申请设立亦不需经财政部核准,得迳洽经济部商业司办理即可。
