On the base of the search model"s analyze, this article analyze and discuss the principle and implement of the fashion Search Engine"s several technology, for example Innernet"s Building, Chinese Syncopate, Auto-Briers Building, the Search Result"s Rank and Several Level Intellective Search Agent.Now, full-text search is a mature technology. Its searchs the all and the one is success. But its accuracy is lack. In fact, the two technologies(Chinese Syncopate and Auto-Briers Building) should be broke through. To Chinese Syncopate, this paper brings forward a new technology that the partial adjust will be brought into effect after the Chinese is syncopated and the notional document brief is put forward to Auto-Briefs Building.
本文在对检索模型分析的基础上,重点对当前流行的搜索引擎中的几大技术(知识库的建立、中文切分、自动文摘的生成、检索结果的排序、多级智能检索代理的实现)的原理、实现进行了分析和探讨;目前,全文本搜索技术作为一种比较成熟的技术,其查全率方面已经做得比较好,但它的查询精度确有待进一步提高,究其原因是:"中文切分"和"自动文摘的生成"这二项技术有待突破,本文中,对"中文切分"提出了切分算法加局部调整技术,对"自动文摘的生成"提出了"概念化的文档摘要",以期能够起到抛砖引玉的作用。

Supposing the hot end of a bare thermocouple is a global thermometer, the authors built a mathematical model for the heat-exchange-based air temperature measurement with the bare thermocouple, deduced the dynamic response time and the deviation estimate formulas in theory. The formulas can be satisfied under the conditions of global thermometers and contact-type temperature measurement.
