After the discussion of the line based and texture energy based palmprint recognition in detail , we analyze the advantages and disadvantages of these two algorithms and suggest an efficient combination of these two ways - - - two - level palmprint recognition 在详细阐述了基于线特征和基于纹理能量的掌纹识别方法之后,我们分析了这两种算法的优缺点,并给出了两种方法的有效结合- - -两层的掌纹识别方法。
After the experiment , the following result will be got : the pole ' s limit load - bearing capability can be enhanced 29 - 43 % with one layer , 44 - 59 % with two layers . the three layers " effect is equivalent to the two layers 通过试验我们可以直观地得到，粘贴一层gfrp的rc柱，其极限承载能力大约可以提高29 43 ；粘贴两层可提高柱子的极限承载能力大约44 59 ；粘贴三层在承载能力的提高上基本等同于粘贴两层的。
Gundersen said she tried the beer but that it tasted a bit odd and was not it turned out that a worker in a bar two floors below had mixed up the pipes , wrongly connecting a new barrel to a water pipe leading to gundersen ' s flat 事后证明，原因出在贡诺森家下楼两层的一个酒吧身上，一名工作人员插错了水管和啤酒管的插头，给贡诺森家输送自来水的水管插头被错插到一个新的啤酒桶里，而酒吧的啤酒龙头里流出的则是自来水。
Integrates circuit devices are mounted on one or both surfaces of the circuit module those multi - layer structure is divided into three types of integration regions including inter - connection integration regions , basic passive device integration regions and high frequency passive device integration regions 积体电路元件安装在电路模组的一或两层的表层，其多层结构分成三种整合区域，包含内部接线整合区域、基本被动元件整合区域和高频被动元件整合区域。
When modifying a feature , in order to maintain the original design intent , it is important to establish the correct correspondence between the previous and current topological entities of a feature model . this problem is known as persistent naming mechanism of topological entities . based on the analysis of existing naming mechanism , a hybrid , simple and effective mechanism is proposed , which is based on both topological faces and design histories 本文在分析当前的已有命名机制和实现的相关工作基础上，提出一个基于面和设计历史的混合拓扑元素永久命名机制，该命名机制采用三个实体命名表来管理和维护命名拓扑元素，由一个两层的表示来支持模型重建，实体模型重建时，系统会自动建立这三个表之间的连接对应关系。
Completion time of the collective communication operation is optimal in the grid environment . in this paper , we gave an example about broadcast , analyzed and compared a topology - unaware broadcast algorithm ( e . g . a binomial tree broadcast ) , a two - level topology - aware broadcast ( e . g 在这篇论文中，我们以广播通信为例，分析比较了未知拓扑型的广播算法，两层的已知拓扑型广播算法（例如ma吵人以及多层的已知拓扑型广播算法（例如mh0十02l并重点研究了网格环境下的多层已知拓扑型广播算法。
By extending the pyroelectric theory of a ferroelectric bilayer , we have presented the effective pyroelectric coefficient of a ferroelectric sandwich structure by use of the electrostatic theory . when the pyroelectric coefficient of the interface has a large deviation from that of the two - sided slabs and the dielectric constant of the interface is low , the effective pyroelectric coefficient of the sandwich structure may be one or two order higher than the largest pyroelectric coefficient of the components 我们应用静多层结构铁电系统的物理性质研究摘要电场理论，推广了铁电双层膜的热电理论，给出了铁电三明治结构的有效热电系数，发现在界面层的热电系数与上下两层的热电系数差异较大，且界面层的介电常数较小的情况下，三明治这种复合结构材料的有效热电系数比单一组份材料的热电系数可以提高一到两个数量级。
Since 1990s , whh the development of web and related technologies such as java technolog , the original computer an hecturehasdewtopedfiom 24edc / sarcnitecturetothe 3 - tiedc / s architecture , and been realizing the popular j2ee application architecture . the ejb - based 3 - tied architecture is one important part of j2ee application architecture 自20世纪90年代以来，特别是web及相关技术，如java的发展，计算机原有的体系结构也从两层的c s结构发展到现在的三层c s结构，并逐渐形成流行的j2ee应用体系结构。
Here is a demo of xdesignerhtmldom , it is a winform program written in c , please use vs . net 2003 to open project . this program parse a topic html document in some bbs , list all topic , build a two lay tree , when use expend a tree node , programm will parse this topic html document , and list all jpg image item . when use click one jpg node , program wile downlaod this jpg image document and dispaly it , if the image size is big , program will save this image content in database buffer . mdb 在此提供一个使用xdesignerhtmldom的范例程序，本程序为一个c编写的winform程序,请用vs . net2003加载工程，本程序功能是解析某个bbs论坛上某个版的主题列表html文档，列出所有主题，生成一个两层的树状列表，用户可以进入某个主题来直接查看该主题的html页面中包含的所有的jpg图片文件,并将大的图片内部保存到应用程序目录下的buffer . mdb数据库中。
