【摘要】 中国数字地震台网(CDSN)自20世纪 80 年代建成并投入运行以来, 有力地促进了我国的数字地震学研究, 扩大并加深了我们对地壳、地球内部构造和地震震源过程的认识, 从而有助于地震预报和减轻地震灾害的研究工作. 随着世界科学技术的发展, 中美双方于 1992年~2001年, 对CDSN进行了二期技术改造.本文综述了CDSN二期技术改造的目标和技术内容;“新一代”CDSN的技术特性和运行状况; 基于 CDSN二期技术改造建立的 CDSN数据通信系统, 研发CDSN数字地震实时分析系统的进展.更多还原

【Abstract】 Since its establishment and operation in the eighties of the 20th century, China Digital Seismograph Network (CDSN) has greatly promoted the research on digital seismology in China, expanded and deepened our cognition about the earth′s crust, the earth′s inner structure and the source process, which is useful to the research on earthquake prediction and reduction of earthquake disaster. Along with the development of world science and technology, the Sino America incorporated two sides carried the second stage of technique update to CDSN from 1992 to 2001. The paper summarizes the goal and technical content of this technique update: technique character and operation status of the new generational CDSN, CDSN digital communication system built in the second stage of technique update, research progress of CDSN digital earthquake real time analysis system.更多还原
