ABSTRACT The purpose of this dissertation is to study the problem of modeling of non—minimum phase random signals, and the retrieval of harmonics in noise by using higher—order statistics as a signal processing tool.

本论文的目的在于，以高阶统计量作为信号处理的工具，研究非最小相位随机信号建模以及噪声中的谐波恢复问题。

Random Access Document Indexing and Retrieval?

随机存取文件索引与检索系统

2The research reveals that successful problem-solving is not only rely on the precise concept internal representation, but also rely on the integrated bundle structure of concept internal representation. The construction process of the integrated bundle cognitive structure, includes the re-establishment and re-formation, retrieval clues, re-adjustment and re-composition of integrating multiple forms of concept internal representation.

概念内部表征的应用过程同时也是内部表征的重构过程，其中包括重构概念多重内部表征形式的捆绑认知结构、概念内部表征的串联和检索线索以及概念内部表征的再调整与再修改等认知过程。

In the ER-Tree, the efficiency of retrieval could be improved by the ways of partition of the vector space with hyper-sphere and R*-Tree s re-insert technology introduced to enhance ER-Tree s capability to represent the data-sets'features.

该索引树用超球体划分多维向量空间，以有利于计算最近邻；吸取R*-Tree树的重插技术，以增强索引树对数据集整体特征的表达能力，从而提高检索效率；通过引入插入安全点和删除安全点概念，有效地提高建树的效率。

In chapter 5 the harmonic retrieval problem in colored non-Gaussian noise is addressed in real domain.

第五章在实数域研究非高斯有色噪声中的谐波恢复问题。

Many real domain applications of MAS, such as information retrieval and data mining on the WWW can be reduced to the problem of searching in an unknown environment.

现在 MAS中的许多具体应用问题也可以归结为对未知环境的搜索。比如 WWW上的信息检索、数据发掘等。当存在信息缺失的情况下，如何设计 MAS系统使之更为有效地搜索是目前 MAS研究的一个重要课题。

To achieve the real semantic-based image retrieval would be the most effective approach to settle the problem.

实现真正意义上的基于语义的图像检索，将是解决"语义鸿沟"问题的最有效途径。

For a good 3D models retrieval system, the geometrical similarity matching method should be reckonable, and be robust to rotation, noise, model degeneracy.

对于三维模型检索系统，三维模型几何相似性比较算法要有较好的可计算性，具有较好的噪声鲁棒性，较好的网格简化鲁棒性，以及三维模型的坐标系旋转鲁棒性。

There are three common personalized recommendatory technologies: information retrieval and extractor, content-based filtering and collaborative filtering, data mining and knowledge discovery.

常用的个性化服务推荐技术包括三种：信息检索与信息抽取、基于内容的过滤和协同过滤、数据挖掘与知识发现。

The practical values of the rediscovery focus on the retrieval and appraisal of electronic records.

新来源观的实践价值集中体现在电子文件检索和鉴定领域。
