| 摘 要： | 为了考察中子与介质相互作用的细致物理过程,得到不同种类中子对所关心物理量的贡献,利用Monte Carlo方法的模拟能力,由中子标识记录中子及其次级粒子的输运历史,在程序中赋予中子一个整型标识变量,记录中子的出身、碰撞过程等历史,在记数时根据该变量的值进行分门别类的统计以达到求解众多物理量的目的。结果表明,该方法能得到其它方法不易得到的物理量,如不同种类中子出壳流等。

| Abstract: | For studing the detail process of neutron's interaction with material and getting the contribution to unknown quantity by various neutrons,a integer neutron flag has been setted in the program according the idea of transport with neutron flag.The neutron flag records what is the source of neutrons,the history of neutron transport,and so on.The results show that the idea is valid because it can get many information obtained hardly by other methods such as the leaked various neutron number. |
