利用地震记录反演震源非均匀特征是目前强震地震学研究中的一个重要的课题。本文在总结现有文献的基础上,对与震源反演相关联的六个环节即震源模型及模型参数、格林函数计算、观测数据、反演准则与目标函数、初始模型与迭代方式、反演... 利用地震记录反演震源非均匀特征是目前强震地震学研究中的一个重要的课题。本文在总结现有文献的基础上,对与震源反演相关联的六个环节即震源模型及模型参数、格林函数计算、观测数据、反演准则与目标函数、初始模型与迭代方式、反演精度与分辨率等进行了初步阐述和分析,同时对震源反演中存在的问题也进行了相应的讨论。 展开更多

And then it puts forward a simplified framework called database-oriented Web framework (DOWF). In this framework, the pages and the data are all managed by database system. In order to get keywords or search a special page, which the users accessed before, users access the static pages by common script procedure (CSP), and access the dynamic pages by functional script procedure (FSP) and CSP. The article expounds the method how to implement DOWF in details. The paper also analyses the mechanism of a DOWF site by implementing a prototype system. At last, the article gives the features of DOWS in search, in security, in reuse of pages and in offline waiting, etc. Key words database-oriented - Web framework - common script procedure (CSP) - functional script procedure (FSP) CLC number TP 391 Foundation item: Supported by Natural Science Foundation of Jiangsu Province (BK2003030).Biography: ZHU Qiao-ming (1963-), male, professor, research direction: Web information processing chinses information processing. 展开更多
