摘　　要：给出了部分解已知条件下求非线性代数方程组非齐次项和系数项的方法.基于优化算法,给出了方便的计算公式.This paper solves the inverse problems of a class of non-linear algebraic equations as its partial solution is known. One is the inversion of its nonhomogeneous terms, and the another is the inversion of its coefficients containing some parameters. The optimization method is applied and convenient formulas for computation gradient are obtained.
