" dxf " and " iges " are two standards adopted by industry widely . though " dxf " has not become the international standard , it has been the industry standard for the support of all kinds of cad softwares Dxf和iges是工业界广泛采用的两个标准，虽然dxf没有成为国际标准，但是由于它得到各种cad软件的支持而成为事实上的标准。
Basing on studied native and foreign development status of geometry sculpture and production model , the paper lucubrates iges data structure , brings forward the conversion method of production data model in virtual machining environment 本文在研究国内外几何造型和产品模型的发展状况基础上，深入研究了iges的数据结构。提出了虚拟环境下的产品数据模型的转换方法。
Then , the gene was cloned into vector pgem - t and subcloncd into expression vector pgex - 6p - l and induced by iptg . western blot analysis showed that the fusion protein expressed could be recognized by the specific ige antibody in the pooled sera 0mmoul的iptg浓度、 15c 37c诱导表达温度和lh 411诱导表达时间范围内，改变相应条件对重组蛋白的可溶性表达没有明显影响。
Cad / cmm interface is the information resource of cmm . the thesis analyzed the structure of iges , got and translated data from it . then , the inspecting part was modeled with opengl Cad软件和三坐标测量机系统之间的数据交换为测量提供了零件信息来源,本文以通用cad文件iges为数据交换介质,对其数据结构进行分析,实现零件信息的读入、转换,并利用opengl完成零件的三维重绘。
In this study , we at first aimed at obtaining the gene encoding the specific ige antibody related proteins by immunoscreening the schistosoma juponi cum adult worm cdna library with the pooled high - titer ige antisera from the individuals living in the schistosome epidemic regions J测定。 jnij序结果显示，该插入片段为1200hp ，第一开读框长507hp ，编码169个氨基酸残基，理论分子量为19 3kdi 。
Netsdbrowser , a 3d graphics browser based on network , is composed of two function modules : iges postprocessor and rendering and interaction module supported by opengl , which constitute function plug - in modules of the 3d graphics browser embedded in the webex netmeeting 基于网络的三维图形浏览系统( net3dbrowser )主要由iges后处理器和以opengl为支撑的绘制与交互操作两大功能模块组成，构成webex网络会议系统的三维图形浏览功能插件。
This method sculpts the entity of complicated model by other cad system , and saves in iges file format , finally machines through entering virtual machining environment using production model conversion interface . that embodies currency and universality of the system 该方法通过其它cad系统对复杂模型进行实体几何造型，再以iges文件格式进行存储，最后运用产品模型转换接口调入到虚拟加工环境下进行加工，着重体现了该系统的通用性和广泛性。
By studying the iges data exchange standard and analyzing iges files produced by the preprocessors of cad systems , comprehend basic line elements and basic face elements constituting parts and summarize the means to get data information of parts and assemblies . 2 通过对iges数据交换标准本身的研究，分析比较由cad系统的前处理器生成的iges文件，了解组成零件的基本线元和基本面元的实体类型，总结出从iges文件中提取零件和装配体数据信息的方法。
Integrating the graphics browser into the netmeeting , including realizing communication interface , transferring shared data , synchronizing scenes . according to methods mentioned above , a prototype system netsdbrowser is developed on the windows 9x / nt / 2000 and unix platforms by c + + , opengl and iges 根据上述思想和方法，我们利用iges作为图形交换标准，以c + + 、 opengl为开发工具在windows9x / nt / 2000以及unix平台上开发实现了一个原型系统net3dbrowser 。
The mechanism of ki 11 ing the schistosomulae in vitro depending on the specific ige antibody were observed . the distribution of the protein encoded by the cloned gene was determined by immuno - electromicroscopy with protein a - colloidal gold . in order to further analyse the epitope features of the protein relevant to the specific ige antibody , the phage display library of random peptides was screened by pooled sera with the specific ige antibody 借助现行生物信息学分析手段，通过互联网进入genbank数据库，对sj43b与已知序列进行同源性比对，应用dnatoois软件对其编码蛋白序列的氨基酸纽成、亲水性、抗原性和可及性进行分析，并在blastp程序下在genbank蛋白数据库中对sj43b编码3人卞医科大学博士学杠论文蛋白进行同源性检索。
