目前正在推广面积组合,野外施工中一般又多采用检波器串、并联相结合的连接方式。在讨论组合检波对干扰波的压制效果时,往往又只根据组合形式(即组合图形)去计算方向特性曲线,忽略了连接方式对组合效应的影响。曾有这样的现象:为了方便起见把不等个数的检波器串联起来然后再并联到大线上。这种连接方式的效果如何?什么样的连接方式恰当?对此问题下面谈一些看法。每个检波器在接收地震波的时候都产生感生电动势。检波器的串联或并联问题实际
Is currently promoting the area combination, the field construction generally use more detector strings, parallel combination of the connection. When discussing the suppression effect of the combined detection on the interference wave, the directional characteristic curve is often calculated based only on the combination (ie, the combination graph), and the influence of the connection method on the combination effect is ignored. There was such a phenomenon: for convenience, the unequal number of geophones were connected in series and then connected in parallel to the large line. What is the effect of this connection? What connection is appropriate? Here are some comments on this issue. Each detector produces an induced electromotive force when receiving seismic waves. Detectors in series or parallel problem
