摘要 §1.引言在核反应系统中,当中子数目足够多时,中子间的相互作用必须考虑,这就导致非线性中子输运方程。在这方面,已出现了一些研究工作,文献[1]对一类非线性中子输运方程,在一定的假定下,用半群方法证明了它的初边值问题解的存在性和唯一性。本文试图用[2]中的方法考察非线性中子输运方程的Galerkin有限元解。在§2中,给出了解的先验估计。在§3中,利用解的先验估计给出了广义解的存在性,构造了Galer- In this paper, we try with the method of [2], to inspect Galerkin finite ele-ment solution for nonlinear neutron transport equation. In §2, we supply the prior estimation of solution. On §3, we construct the solution of Galerkin finite element.At the same time, we use the prior estimation of solution to prove existence and error estimation of the generalzeb solution.
