在地震勘探中,爆炸讯号需要十分准确,用多次复盖方法工作时,爆炸讯号尤为重要。过去在爆炸放大器之后,加接双稳态线路,爆炸讯号波形稳定了,但由于“自动放炮”回路和爆炸线对讯号线会产生感应,所以爆炸讯号仍不准确。为了获得准确的爆炸讯号,有两种途径,一是消除各种感应,一是缩短“自动放炮”碰点到爆炸的时间,使之小于1毫秒,这样即使有感应也不影响爆炸讯号的准确性。两种方法比较来看,后一 In seismic exploration, the explosion signal needs to be very accurate, with multiple cover method work, the explosion signal is particularly important. In the past, the bistable circuit was added after the amplifier was exploded, and the waveform of the explosion signal was stable. However, the signal of the explosion was still inaccurate due to the induction of the signal line by the automatic blasting circuit and the explosion line. In order to obtain an accurate explosion signal, there are two ways, one is to eliminate a variety of sensors, one is to shorten the “automatic shot” touch to the explosion time, making it less than 1 millisecond, so that even if the induction does not affect the accuracy of the explosion signal Sex. Comparison of the two methods, the latter
