查询词典 a source of information

Through the source code audit such as RATS software can find the flaw information of level of partial source code, but after all the majority that software of source code audit searchs spills over for the existence buffer such as Strcpymemcpy the C function that involuntary discharge of urine has, the measure that adopts audit source code so will undertake flaw is dug is coefficient of a possibility very small leak digs a technology, and the flaw that although also can find a few software,checks in the light of the black box of software, but possibility coefficient also is met lesser, a few undertakes flaw is dug idea that are in abroad already slowly promotion writes black box to check code for oneself, the module of a certain function that is aimed at system or software next undertakes modular flaw digs a technology.

通过RATS等源代码审计软件可以找到部分源代码级别的漏洞信息，但是究竟源代码审计软件寻找的多数为strcpymemcpy等存在缓冲区溢出遗患的C函数，所以通过审计源代码的办法来进行漏洞挖掘是一个可能性系数很小的漏洞挖掘技术，而针对软件的黑盒子测试虽然也能找到一些软件的漏洞，但可能性系数也会较小，在国外的一些进行漏洞挖掘的办法已经慢慢的提升为自己写黑盒子测试代码，然后针对系统或软件的某个功能模块进行模块化的漏洞挖掘技术。

Taking customer domain for example, an ontology-based customer metadata model is build and formalized in description logics. Then two kinds of modes for customer information sharing are studied. The two modes are to construct a global c ustomer m etadata m odel w ithin a n e nterprise a nd t o c onstruct a mapping mechanism between customer metadata models located on different enterprises respectively. In the first mode, an information source is regarded as a 3-tuples, including a metadata model, a concept relation set and a resource data set.

DunHuang documents is a valuable information source. It accumulates, exchanges and spreads the cultural information effectively by symbols and carriers on time and space. Furthermore, the discovery of the old newspaper DunHuangJinZouYuanZhuang provides the oldest newspaper's authentic proof for the spreading history of news. So, its value is not to be sneezed at.

由于敦煌文献本身非常有效地在时间上、空间上用符号和载体积累、交流并传播着文化信息，是一种极有价值的信息源；同时敦煌进奏院状的发现又为新闻传播史提供了最早的报纸实证，因而它在传播学方面的价值也非同一般，不容忽视。

The title and bill of material in engineering drawings are important data source for product data integrated management. In order to reuse the CAD data, the paper presents an effective method for extracting part information from existing engineering drawings. Through analyzing the format of title and bill of material, several shape-position characteristics of tables are summed up from the view of macro-layout and microstructure. A new method to automatically extracting drawing information based on cell-grid and feature-point is proposed along with its algorithm principle and implementation steps. A software package based on the method mentioned above is developed and used in practice.

According to the function of distributed emulator, optical information processing and image multi-object tracking system, the following three aspects were emphasized in this dissertation. Firstly, a vast virtual terrain, ground radar models and canyons were created for the distributed emulator with modeling software Creator. The radars were driven to scan during emulating and the real time terrain code was sent to Radar module. Secondly, an optics channel simulating the optics camera of a virtual aircraft was implemented with simulating software Vega. The 2-D information got from the channel was translated and sent to multi-sensor information fusion system as an optics information source. Thirdly, the dissertation studied some motion estimation methods and analyzed the factors which influence the speed and the precision of the block matching algorithms. Then an improved block matching method was proposed for image multi-object tracking system and applied in the system combined with frame difference method.
