【摘要】 基于网络B/S模式地震波形数据实时浏览,在现代地震研究与数据服务方面具有重要作用并且技术亟待提高。文章解决了基于B/S模式动态调阅服务器端数据库系统中的波形数据并即时显示、编辑的问题,重点研究了Java2D在波形曲线表达方面的局限性,并针对由均匀大数据集构成的曲线表达提出了较为快速的算法,最后给出了该算法在实际中的应用。更多还原

【Abstract】 Browsing remote seismic waveform based on B/S schema is of significance in modern seismic research and data service, and the technology should be improved urgently. The problem to access, browse and edit the waveform data on server from client only using browser has been solved. Especially, the authors focus on the shortcoming of Java2D in expressing waveform data, and then propose a faster algorithm aiming at expressing curves consisting of well-proportioned large dataset. At last, an example of the algorithm in practice is given.更多还原
