摘要
本文通过将ｎ阶区间数方程转为带有某些约束条件的代数方程组，进而给出了ｎ阶区间数方程的求解方法。该方法也适用于解另一类线性区间数方程．
In this paper, we transform the n-th order interval number equation into general algebraic equation group with certain retraint conditions, subsequently put foward the solution for finding the interval number equation. This method can also be used to find another class linear inetrval number equation.
