摘　　要：详细介绍基于DSP技术的4πβ-γ符合测量装置的硬件和软件。该装置采用自行研制的数字符合采集器代替传统的符合测量装置中的单道、门产生器、符合电路和定标器,可大大提高测量效率,降低硬件成本。通过实验验证该装置设计是成功的。The paper illustrates the hardware and software of the 4rcl3-T coincidence measurement device based on DSP technology in detail. In such device, the single-channel analyzer, gate generator, coincidence circuit and scalar in the traditional coincidence measurement device are replaced by the digital coincidence acquirer which is researched and manufactured by respectively improved, and the hardware cost will be lowered. The comparison experiment shows that thedesign of such device is a success.
