摘　　要：利用matlab仿真产生了氡及其子体的仿核脉冲数据,它满足氡及其子体的衰变规律;同时根据产生的数据,利用matlab仿真延迟符合法分辨氡的短寿命同位素219Rn;探索在延迟符合测量氡短寿命同位素219Rn最佳的开门时间;通过仿真对符合测量装置的研究具有指导作用。It produces the data of decay pulse serials of radon and its daughters by using matlab , it conforms the decay law of the radon and its daughters, and the time-interval of the neighboring pulses conforms the exponential distribution law as well And then we discriminate 219Rn from radon isotopes by using a software delayed coincidence counter, in which the best time to gate-time is about 6ms in the system of delayed coincidence measure, it is helpful to the study of the radon isotopes discrimination device by delayed -coincidence measurement.
