【摘要】 山西数字遥测地震台网于 2 0 0 0年 1 0月 1日投入考核运行。为使数字遥测地震台网与模拟地震台网测定的时、空、强地震参数顺利接轨 ,尽快发挥数字资料在日常工作中的效益 ,将山西数字遥测地震台网产出的资料与模拟地震台网产出的资料作了全面细致的对比分析 ,研究了它们之间的相关程度、一致性、差异性。结果表明 ,数字地震观测系统比模拟地震观测系统具有更高的拾震率。得出山西数字遥测地震台网产出的资料与模拟地震台网产出资料相关性较好、定位结果在误差范围之内、符合《数字地震及前兆观测技术规范》要求的结论。更多还原

【Abstract】 The Digital Seismic Network of Shanxi Province was put into test operation on Oct.1,2000. In order to keep continuity of determined parameters such as time, location and size of earthquake from digital data to analog data and replace analog system with digital one, the data from the Digital Seismic Network of Shanxi Province is compared with analog data in details. The correlation, consistency and differences between these two kinds of data are investigated. The results show that the more earthquakes can be recorded by the digital system than by analog one. The results from the digital system are well correlated with those from analog system. The residual errors of earthquake location results from the digital system are less than the values regulated in the ‘Observation Code’.更多还原
