点堆随机动力学微分方程的推导

Deduce on Stochastic Dynamic Differential Equations for Reactor

针对弱中子源反应堆启动过程中的中子数密度和缓发中子先驱核随机涨落现象,本文将随机微积分理论引入了反应堆物理研究,在点堆模型的假定下,推导了可描述这一涨落现象的反应堆随机动力学微分方程组,重点介绍了这一物理问题和方程组的推导过程。

In this paper,stochastic calculus theory is introduced into reactor physics to deal with the phenomenon of stochastic fluctuation of neutron number density and delayed neutron precursor nuclei in the start-up process of weak neutron source reactor.Under the assumption of point reactor model,the reactor stochastic dynamic differential equations describing this fluctuation phenomenon are derived and established.
