摘　　要：研究了利用区域数字地震台网CTS1-EDASC24速度型甚宽频带地震仪和FBS3-EDASC24速度型宽频带地震仪的速度记录仿真加速度时程的有关技术与应用问题,其中包括:仿真方法的选取,仪器性能和仿真参数的分析,仿真加速度时程与SLJ100-GDQJⅡ加速度型强震仪记录结果的比较,福建及邻近地区所选用地震的仿真加速度时程(1998-07-2008-07),仿真结果在合成场地设计地震波中的应用等方面,并提供了具体的应用算例。In this paper, related technical and application problems of simulating acceleration time histories from velocity records of velocity seismograph CTS1-EDASC24 and FBS3-EDASC24 of local digital seismograph network are investigated, including the choice of simulation methods, analysis of instrument characteristics and simulation parameters, comparison between simulating acceleration time histories and records of acceleration acceleration time histories of selected earthquakes in 2008.7）, application of the results in synthesizing application examples are provided. The results improve seismograph SLJ100-GDQJ Ⅱ, simulating acceleration time histories of selected earthquakes in Fujian and its adjacent areas （1998.7-2008.7）, application of the results in synthesizing site design earthquakes. And specific application examples are provided. The results improve the value of velocity records in provincelevel digital seismograph network.
