数字符合技术是目前国际放射性核素计量学研究的热点，是一种很有发展前景的、灵活的核脉冲处理技术．本文介绍了一种数字符合方法的实现方案，利用高速数据采集卡从探测器采集到的数据，并根据数字符合的特点，用Matlab软件对数字符合技术中的死时间、滤波、基线校正、脉宽分析和符合等算法进行研究．采用^60C0源的β-γ符合测量活度实验进行验证，并得到了一些初步结果．

Digital Coincidence Counting（DCC） is a promising, flexible nuclear pulse pro- cessing technology. In this paper, an implementation scheme of the digital coincidence is introduced. The nuclear detector signal was sampled to the computer by the high speed ac- quisition card, and then processed through Matlab. The relative Coincidence processing al- goriths include deadtime processing, digital filter, baseline correction, pulse width analysis and digital coincidence algorith, and the preliminary results ofβ-γ coincidence measure- ment with 6~Co source show that the realization scheme of DCC in this paper is practical.
