It has important significance in critical and subcritical experiment research . on the one hand , it can make theoretical estimate for experiment assembly in advance . on the other hand , it can compare with experimental value and check up the theoretical computation method and nuclear data 它在临界及次临界实验研究中有着重要意义，一方面可以对实验装置的设计作理论预估，另一方面可以与实验测量值进行比对，检验理论计算方法和核数据。
Along with the fast development of computer technology , now pcs ( personal computer ) are powerful of processing data . many works completed by the middle or small size computers not long ago , now can be done by pc computer . the pc control the mca to transfer the nuclear data to pc through the computer interface , then the pc process the data with real time feature 随着计算机技术的飞速发展， pc计算机已有很高的数据处理能力，过去需要中小型计算机完成的多道数据获取，大都可以用pc机完成：将核数据通过计算机接口送入pc机后， pc机能实时地处理数据，同时完成对多道数据采集器的控制。
In recent years , with the rapid development of the study in the field of atom - molecule physics , the experimental equipments turned into larger and larger , the number of the parameters needed to be detected increased , the precision of measurements was improved , the measuring and controlling distance was expanded 近年来，随着原子分子物理研究的广泛深入发展，相关实验装置变得越来越庞大，需要监控参数的种类增多，测量精度提高，测控距离加大，这样一些变化给核数据获取和控制系统提出了越来越高的要求。
