摘要 本文讨论了中子输运方程的解的存在性。使用有限元方法求解中子输运方程,并使用Landweber方法求解源项反演问题。给出了算法和数值模拟结果,验证了算法的有效性。 The existence of a unique solution for the neutron transport equation is discussed. Using the finite element method (FEM) for direct problem of neutron transport equation and Landweber method for reconstruction of the source term, some properties are discussed and numerical simulations are presented. The calculating results show our algorithm is reasonable and effective.
