摘要
本文采用蒙特卡罗计算程序MCNP(Monte Carlo N-Particle Transport code),对煤炭中Ti、Si元素量的变化前后14MeV脉冲中子源在煤中形成的中子场进行了计算。其中Ti元素量的变化对中子场影响程度较大,Si元素则较小。实验事实验证了分析结果。
In this paper, with the special program of MCNP （Monte Carlo N-Particle Transport code）, before and after changing of Ti and Si contents, we have calculated the neutrom field in coal formed by the 14 MeV pulse neutron source. Increasing the content of Ti can obviosly change the neutron field, however, the change is unconspicuous for Si. The imitated experiments validate the analysis conclusion.
