摘　　要：阐述了基于虚拟仪器的采用LabVIEW和通用数据采集卡开发核能谱数据采集系统的全过程。它采取了连续采样和幅度提取的方法,直接对核探头输出的电压脉冲信号进行定性和定量分析。经测试,系统能满足实际测量的要求,并且可以根据需要进行扩展。The whole process of designing nuclear spectrometry data acquisition systemwas particulanzedwith LabVIEW and data acquisition board , based on virtual instrument technology. It can analyze the output of the radiation detecor and give the height spectrum by the method of the continuous real-time data acquisition and the abstraction of pulsesignal amplitude. The simple test shows that this system can meet the demand, and it can be easily expanded according to the situation.
