| 摘 要： | 美国ＴｅｒｒａＴｅｃｈｎｏｌｏｇｙ公司生产的ＤＣＳ－３０２数字地震仪原来配用ＳＳＡ－３０２力平衡加速度计，用于观测地震的近场地面运动加速度。本文设计了一套装在地震计与记录器之间的前置放大器，使ＤＣＳ－３０２记录器可与英国制造的ＷｉｌｌｍｏｒｅＭＫ３型动磁式地震计配用，既能记录近震，又能记录远震，扩大了ＤＣＳ－３０２数字地震仪的使用范围。文中给出了记录实例。

| Abstract: | The DCS-302 digital seismic recorder produced by the American Terra Technology Co. is formally equipped with SSA-302 force-ballanced accelaration seismometer. This research has fitted the DOS-302 recorder with Willmore MK 3 moving-magnet seismometer produced by the Britain , using pre-amplifier designed by an author between them. With the recording ability extended , the adapted recording system can be used to record both near and far seismic events. A field recording example is given. |
