一、前言 近十年来,地震勘探系统发展上的技术进步主要为24位数据采集和数据处理中的并行计算。目前这些技术在日本国内地震勘探上虽用得不太多,但今后将会稳步地采用。文中介绍了这些技术,并顺便介绍一下已产品化的24位地震仪和并行计算机,同时还介绍了并行计算机实际模拟试验情况。 I. Introduction In the past decade, the technological advancement in the development of seismic exploration systems has mainly been the parallel calculation of 24 data acquisition and data processing. At present, although these technologies are not used much in the seismic exploration in Japan, they will be steadily adopted in the future. The paper introduces these technologies and, by the way, introduces the 24-bit seismographs and parallel computers that have been commercialized. At the same time, it introduces the actual simulation experiments of parallel computers.
