摘　　要：介绍了核爆炸次声波产生的机理和接收原理,提出了双电容式次声接收器的设计方法,并将CPLD技术应用其中,与单电容式接收器相比,改进后的接收器接收灵敏度提高一个数量级,大大提高了动态范围,整体性能得到了很大的改善。The article introduces the theory of infrasonic generation and reception of nuclear explosion. Give an idea of the design of double capacitances infrasonic receiver using CPLD technology in it .Compare with the single capacitance infrasonic receiver, sensitivity of the improved receiver can be improved scores of times, dynamic range can be improved largely , and the whole performance gets improvement a lots. 
