摘要： 本文推导了考虑中子之间碰撞的非线性中子输运方程,提出了求解该方程的n-n逐次碰撞展开法,并利用此方法把方程化为适于数值求解的线性输运方程组的形式,编制计算程序进行了数值计算,讨论了解的物理意义。

Abstract: In this paper the nonlinear neutron transport equation is derived. The collisions between neutrons are taken into account in this equation. In order to solve this equation we proposed the successive n-n collision expansion method.By using this method the equation is deduced to the form suitable for numerical computation. The numerical calculation is performed and the significance of the solution is discussed.
