将非线性微分方程的独立通解法推广到差分方程,给出了一类非线性差分方程的精确解,该精确解是由若干个独立通解共同构成,且独立通解的个数与差分方程的次数n无关.
The paper shows the exact solution of a kind of non-linear difference equation by extending the undependent general solution method from non-linear differential equation into difference equation.The exact solution is formed by some undependent general solutions whose number is independent of the degree n of the difference equation.
