| 摘 要： | 提出用中子方程的高阶谐波进行通量拟合的方法。给出了利用高阶谐波的双正交性。用带源修正的源迭代方法求高阶谐波的具体流程和公式。不但首次实现了直至３维、任意阶的高阶谐波计算，而且初步验证了用高阶谐波进行通量拟合的能力。

| Abstract: | This paper proposes the flux mapping method using the higher order harmonics of the neutron equation. Based on the hi-orthogonality of the higher order harmonics, the process and formulas for higher order harmonics calculation are derived via the source iteration method with source correction. For the first time, not only any order harmonics for up-to-3-dimensional geometry are achieved, but also the preliminary verification of the capability for flux mapping have been carried out. |
