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。
In order to investigate the detailed physical process of neutron-medium interaction, the contribution of different kinds of neutrons to the physical quantities of interest is obtained. Monte Carlo simulation capability is used to record the transport history of neutrons and their secondary particles. In the program, neutrons are given an integer marker variable to record the history of neutron origins and collisions. When counting, the statistics of the variables are divided into different categories so as to achieve the purpose of solving many physical quantities. The results show that this method can get the physical quantities which are hard to get by other methods, such as the different types of neutron shedding flow and so on.
