摘　　要：概述了重子数实验的实验装置,其中包括探测器装置和数据获取系统。简述了探测器的组成、功能和性能;着重叙述了数据获取系统之构成、功能及所解决的问题。触发判选与数据获取系统较大地抑制了噪声,提高了信噪比和测量精度。该数据获取系统有一定的通用性,其设计方案不仅用于重子数实验,也适用于其他实验如双β实验中所需的符合测量等。The set-up for a baryon number experiment including the detector and the data acquisition system is introduced. The component, the function, the character of the detector is described. The data acquisition system including the constitution, the function, the solved problems , and so on, is mainly introduced. The system can decrease the noise and can increase the ratio of signal to noise and the measurement precision. The scheme of this system can also be applied in other experiments, for example, the coincident measurement in the double β decay experiment etc. The design is efficient.
