摘要
针对中子测井问题，研究非定常Ｂｏｌｔａｍａｎｎ中子输运方程的确定型数值求解方法，给出了求解Ｂｏｌｔｚｍａｎｎ方程的球谐函数展开和流线扩散有限元耦合方法。
In this paper, a new numerical method, the coupling method of spherical harmonic function spectral and streamline diffusion finite element method for unsteady Boltzmann equation in the neutron logging field is discussed, and the convegrence and error estimations of this scheme are proved. It's applications in the field of neutron logging show it's effectiveness.
