摘要
在近临界核系统中,弱源中子的涨落行为是一个典型的Markov分支过程。文章介绍用Markov理论与母函数方法建立相关微分方程,并导出近似解析解,着重对常数源在系统中的涨落作了数学描述,给出了数值例子。
The neutron fluctuation behavior in near critical nuclear system with a weak neutron source is treated with Markov process. The paper introduces a differential equation derived from Markov theory and probability generating function. An approximate analytic solution of the differential equation is deduced. The neutron fluctuation behavior for a constant source system is emphasized and analyzed. An numerical example is provided as well.
