中文摘要：
利用最小二乘有限元离散纵标方法，对一阶中子输运方程进行离散求解，给出了基于非结构网格的角度相关再平衡加速算法及其外推算法。基准问题的计算结果表明，求解问题的计算时间可减少到原来的34％～50％，对强散射问题也同样有效。
英文摘要：
The first-order neutron transport equation is solved by the least-squares finite element method based on the discrete ordinates discrefization. The angular dependent rebalance （ADR） acceleration arithmetic and its extrapolate method are given. The numerical results of some benchmark problems demonstrate that the arithmetic can shorten the CPU time to 34% -50% and it is effective even for the strong scattering problem.
