针对核物理实验的特殊性,设计了一套基于LabVIEW平台的、在核物理实验中常用的核仪器仿真系统,包括核随机信号发生器、单道脉冲幅度分析器、定标器等插件仪器的仿真与集成.运用该系统进行了部分本科核物理实验的实验验证.结果表明,系统中核随机信号发生器所产生的仿真信号符合核脉冲信号的统计规律,仿真系统界面逼真,操作与真实的实验操作基本一致.该仿真系统的应用对于掌握常规核辐射探测方法及避免实验中可能的辐射损伤具有实际意义.
針對覈物理實驗的特殊性,設計瞭一套基于LabVIEW平檯的、在覈物理實驗中常用的覈儀器倣真繫統,包括覈隨機信號髮生器、單道脈遲幅度分析器、定標器等插件儀器的倣真與集成.運用該繫統進行瞭部分本科覈物理實驗的實驗驗證.結果錶明,繫統中覈隨機信號髮生器所產生的倣真信號符閤覈脈遲信號的統計規律,倣真繫統界麵逼真,操作與真實的實驗操作基本一緻.該倣真繫統的應用對于掌握常規覈輻射探測方法及避免實驗中可能的輻射損傷具有實際意義.

For the special nature of the nuclear physics experiment, a NIM-standard nuclear instrumenta-tion system is simulated based on LabVIEW, including plug-ins simulation and integrated devices such as a nuclear random signal generator, a single channel analyzer, a scaler and a data-processing module. In order to verify the system, some undergraduate nuclear physics experiments were done. The results show that the simulation signals of the nuclear random signal generator accord with the rule of statistical nature of the nuclear random pulse, the GUI of simulation system is verisimilar, simulation operation is basical-ly the same as real experimental operation. Application of the simulation system has practical significance in mastering conventional nuclear radiation detection methods and avoiding radiation damage of the experi-ments.
