介绍了一种基于模糊C-均值聚类的脉冲形状甄别方法，对α/β粒子进行甄别。设计了一种新的α/β粒子辐射检测电路；采用单探头闪烁体探测器采集环境中的α/β粒子；实验表明，相比脉冲幅度识别法，模糊C-均值聚类算法识别将6190 cps0420α源的α粒子计数率提高了42．9％，α道对β道的串道比降低了15．9％；将05-05β源的β粒子计数率提高了31．8％，β道对α道的串道比降低了7．7％。%A pulse shape recognition method based on fuzzy C -means clustering for the discrimination of α/βparticle was presented .A detection circuit to isolate α/β-particles is designed .Using a single probe scintil-lating detector to acquire α/βparticles.By comparing the results to pulse amplitude analysis , it is shown that by Fuzzy C-means clustering α-particle count rate increased by 42.9%and the cross-talk ratio of α-βis decreased by 15.9%for 6190cps 0420 αsource;β-particle count rate increased by 31.8%and the cross -talk ratio of β-αis decreased by 7.7%for 05-05βsource.
