The approach to exactly calculate geometric parameters of subdivision surface , such as limiting point , tangent vector and normal vector , are illustrated . ( 2 ) the number of geometric elements ( vertex , edge , facet ) within control mesh grows exponentially as the increase of subdivision levels in general subdivision schemes ( 2 )在正常的曲面细分过程中,控制网格上几何元素(顶点、边、面)的数量是按照几何级数增加的,会产生庞大的冗余数据。
With the rapid development of internet technology and then the surpassing increase of all kinds of information characterized by geometric progression , the intellectualized information retrieval has become a major research topic , for the traditional information retrieval ca n ' t meet the requirements of users 随着因特网技术的迅速发展,因特网上信息成几何级数增长,传统的信息检索服务已不能满足用户的检索需求,因此智能信息检索成为重要的研究课题。
With rising of the internet ' s knowledge on the way of geometric series , the search engine , which is looked as a tool that users get information with , its function had been regarded . at present , an excellent search engine can increase the number of the web site ' s accessing largely and has been the web site ' s appearance 随着internet网上的知识呈几何级数式的增长,搜索引擎作为一个查询用户所需信息的工具,其作用性越来越受到人们的重视;目前,一个优秀的搜索引擎能够大大地提高一个网站的点击率,搜索引擎已经成为一个网站的门户。
With the rapid development of internet , digital library information resources are increasing with geometric series . in the face of tremendous amount of network resources , how to organize and describe digital library information resources so as to readers can find and utilize them expediently , is a problem that the librarians must solve urgently . firstly , this article describe the digital library information resources is different of other resources . it has its only orgnize and orgnize way . secondly , standards and specifications in the contents creation and resources description can be created in the course of the building of digital information resources . in these days , there are many metadata schemas in organizing digital library information resources . metadata schemas for resources description and domain specific markup languages have evolved dramatically during the last several years . this paper analyzes and discusses several metadata schemas . dublin core has been dramatically applied to the libraries for its advantages 随着internetr的讯猛发展,数字图书馆信息资源呈几何级数增长。面对浩如烟海的网络信息资源,如何来选择一种对数字图书馆的信息资源进行组织与描述的标准,以方便读者查找和利用,成为图书情报学界急待解决的问题。本文首先介绍了数字图书馆信息资源不同于其它的信息资源的特点,提出数字图书馆信息资源有自己独特的组织原则与组织方式;其次,在数字图书馆信息资源的建设中,在内容创建和资源描述方面时应遵循相应的标准规范,目前存在的多种组织数字图书馆信息资源的元数据标准,其中以处理文献资源为基本目的的元数据标准和专业置标语言近年来都在以前所未有的速度向前发展。
For several decades , many scientists have been working hard at reducing production cost , simplifying the industrial process , increasing the coefficient of propagation , but as for the rapid propagation of most economic plants , people still can not transform the technique of tissue culture into great productivity in large scale 这一点更像组织培养试管快繁的优点。越到后面的代数,繁殖的种质资源材料越多,繁殖的速度越快,成本越低。快繁苗木随著按几何级数高效增殖的同时,快繁生产成本却不断得到稀释。
The study shows that the early and late seed rains of constructive tree species in evergreen broadleaved forest at chongqing simian mountain had no activity . the bigger the seeds of the species and the earlier or later the seeds of the species matured , the higher the proportion of the seed rain damaged by animals . the quantitative variation of seed rain , active seed rain and seed bank did not take place at the same time . at early time , the number of seed banks of castanopsis fargesii , lithocarpus glabra , quercus myrsinrefolia , castanopsis plasyacantha , cinamomum subavenium . which own more active seed rain increased by geomitric series . the seed banks of castanopsis orthacantha and schima argentea were small , only survived a short time , and did not sprout next year . the quantitative dynamics of seed banks and their increasing or decreasing rates were decided by the proportion damaged by animals , dying speed of seeds and their resistance to pathogens and adverse circumstances , and the state of seed germination 对重庆四面山常绿阔叶林建群种种子雨、种子库的研究表明,建群种早期和晚期的种子雨无活力;种子偏早或偏晚成熟及大籽粒的树种,其种子雨被取食的比例大;种子雨、有活力种子雨、种子库三者的数量变化不一致;有活力种子雨量较大的栲、石栎、小叶青冈、扁刺栲、香桂等,其种子库密度在早期以近几何级数的方式增长,元江栲、银木荷种子库小,存在时间短,翌年无一年生萌发苗;种子库数量动态、消减率动态决定于种子被取食的强度、种子衰老的速度以及种子对病菌、逆境的抗性和种子萌发的整齐性
The design complexity and system function of electronic system have been increasing largely , the competition from the global also shorten the design period , therefore , the demand for the tools of electronic design automatic is tremendous and the requirement for efficiency of eda tools is more and more precise 电子系统的设计复杂性和系统功能一直在呈几何级数增长,全球的竞争又加剧了产品开发周期的缩短。因此,对电子设计自动化工具的需求越来越迫切,要求也日益提高,这一切促进了eda的发展,加速了设计方法和设计工具的更新换代。
As indicated by the research of humanity hypothesis theory and incentive theory of the western , incentive can make people exploit their potential capability . for the executives , the direct suppliers of the entrepreneur source , the efficient incentive can have the geometric series amplified effect on social economy 西方的人性假设理论和激励理论的研究表明,激励能够使人发挥更大的潜能,而对于企业家资源的直接供应源经营者来说,有效的激励能够对社会经济起到更大的呈几何级数的放大效应。
