【摘要】 着重介绍了蒙城地震台FBS-3系统标定参数的测定与计算,同时也总结了标定软件使用的步骤和注意事项。对仪器进行日常脉冲标定、特定情况下的正弦波标定可以对仪器系统的工作状态有一个量化的评定,以此来判定仪器性能的变化及其稳定程度。2006年7月份,对FBS-3数字化测震观测系统进行了一次标定,此次标定作为每年一次系统正弦波标定的最终结果。与2005年7月份标定结果对比分析,两次标定结果差别不大,符合规范要求,观测系统性能稳定。更多还原

【Abstract】 The authors highlight the measurement and calculation of the FBS-3 digital monitoring system of Mengcheng Seismic Station,and summarize the steps and regulations of the software on demarcation.A quantized assessment of instrumental system’s operating state can be made through daily pulse and sine wave demarcation in special cases,thus the instrument’s change and stability can be measured.In July 2006,we demarcated the FBS-3 digital monitoring system and this demarcation was the final result of annual sine wave demarcation.It was almost the same as that of July in 2005 and agreed with the request of criteria.The monitoring system is stable.更多还原
