本文从地震勘探对地震仪器的要求出发,论证了多道地震仪是地震仪发展的必然趋势。依据地震仪整机的基本理论,全面分析了常规地震仪,特别是遥测地震仪中限制道数扩展的各种因素,并介绍了相应的扩展道数的对策和措施。

In accordance with the demand in technic for seismic recording systeni.it has been pointed out that to develop the multichannel seismic recording system is an inexorable trend in seismic instrumentation manufacturing. Based on the basic theory of the overall seismic recording system,factors preventing the conventional seismic recording system,especially the telemetry data acquisition system from increasing Iheir channels were analyzed. The ways anJ the measures to deal with the problem above mentioned were introduced here in this paper.
