Similar to that, compared to the mouse model of memory impairments of acquisition, retention and retrieval induced by scopolamine, sodium nitrite and ethanol D-galactose, the blank control group, SZF group and positive control group could prolong the latency and reduce errors in step-down test and avoiding dark test.The result bioassay showed that SZF group incresed the activity of SOD and level of TChE and decreased the level of MAD in mice brain tissue.

东莨菪碱、亚硝酸钠和乙醇分别诱导的小鼠学习记忆获得、巩固和再现障碍实验结果表明，与模型组比较，在跳台和避暗测试中，空白对照组、SZF复方和阳性对照组均能延长跳台实验和避暗实验的潜伏期(P.01，P.05)，均能减少实验中的错误次数(P.01，P.05)。D-半乳糖、东莨菪碱、亚硝酸钠和乙醇诱导的小鼠脑组织生化测定的结果显示，与模型组比较有显著差异，SZF复方表现为能使脑组织中总SOD活力上升，MDA含量降低，TChE含量上升。

An ontology defines a common vocabulary for researchers who need to share information in a domain,which shares the same function of the traditional thesauri in information retrieval.

Ontology为需要共享某一领域信息的研究人员提供了通用的词表，而这正是传统的叙词表在信息检索中所起的作用。

In this paper, some methods of fuzzy mathematics suah as the direct method of fuzzy pattern recognition, the method of fuzzy clustering analysis the method of fuzzy information retrieval, and the recently advanced method of fuzzy fractal dimension have been applied to earthquake monitoring and prediction in the Surrounding Capital Area based on the seismicity and earthquake precursors. The seismic and unseismic precursors before both the Tangshan M=7.8 great earthquake in July, 1976 and the Datong-yanggao M...

本文把模糊数学中的模糊模式识别的直接方法、模糊聚类分析方法、模糊信息检索方法和新近提出的模糊分维方法应用到以地震活动性和地震前兆为基础的首都圈地震监测预报当中，分析研究了发生在这一地区的两次大地震，即1976年唐山7.8级和1989年大同6.1级地震前用模糊数学方法识别出的地震学前兆和非地震学前兆，并对这一地区大地震的长期和中短期模糊预报方法与途径进行了简要的讨论。

Based on fractal coding the index file have two characters: First, similar images have similar iterative function so as to produce similar index file, and the similar index file can retrieval the similar image; Second, unsimilar images have unsimilar iterative function, vice versa.

这个分形编码方法建立的索引文件具有三个性质：(1)相似图像有相似分形函数能产生相似索引文件，相似索引文件能检索到相似图像；(2)不相似图像有不相似分形函数，反之亦然。

Based on fractal coding the index file have two characters:First, similar images have similar iterative function so as to produce similar index file, and the similar index file can retrieval the similar image; Second, unsimilar images have unsimilar iterative function, vice versa.

将图像经分形编码，得到每张图像的迭代函数伴随图像存入数据库中，成为该图像的索引文件，这样对数据库进行搜索时，将针对此索引文件比对，找出与查询图像相似的图像。

Along with the development of multimedia technology and web technology, The multimedia information including imgae video, audio etc. emerges in a large amount. How to organize, express, manage, inquiry and retrieval those large capacity and unstructural information become the most urgently problem at present.

随着多媒体技术和web技术的发展，包括图像、视频、音频等的多媒体信息大量涌现，对这些海量而且包含大量非结构化信息的数据如何组织、表达、管理、查询和检索就成为目前需要迫切研究解决的问题。

As a new research area, Information Extraction aims at extracting theinteresting information from the unstructural electronic texts (such as news,literature and materials, including the information on the Net) and convertingthem into structural database file, which is easy for the users retrieval, statisticsand decision.

针对从非结构的电子文本提取感兴趣信息，并将其转换成结构数据库文件，方便用户检索、统计和决策支持，信息提取被看作新的研究领域。

It is very important to manage the enormous size of image databases and retrieve images we need. The drawbacks of traditional text-based image retrieval are that it is time consuming and labor consuming when labeling the keywords on the image, which often untruly represent the content of image.

传统的基于文本的图像检索的缺点通常是为图像加上关键字比较费时费力，常常不能准确地反映图像的内容，且带有很强的主观性，不同的人会有不同的理解，这已不能满足用户的迫切需求。
