摘　　要：针对既往地质勘探实践中存在着强烈震动、泥水量大、容易炸断线路等情况,参照检测垂向叠加震源的技术标准要求,开发出一种适用于检测垂向叠加震源的电子延迟设备,对其控制电路进行精确化设计。并通过在野外工程项目实践的应用,检测验证电子延迟器的实用性。结果表明,采用该电子延迟系统激发获得的人工震源,可以明显增加地震有效波的下传能量,频宽相应拓展,为检测垂向叠加震源提供了一种崭新的思路。In view of the strong vibration,large amount of mud and water,easy to break lines and other conditions in the past geological exploration practice,referring to the technical standards for detecting vertical superposition source,an electronic delay device suitable for detecting vertical superposition source was developed,and its control circuit was precisely designed.The practicability of the electronic retarder is verified by its practical application in field engineering projects.The results show that the artificial seismic source excited by the electronic delay system can obviously increase the down-transmission energy of the effective seismic wave and expand the frequency width accordingly,which provides a new way of thinking for detecting the vertical superposition seismic source.
