中文摘要：

它是很困难的，有时不可能，得到复发关系的一个公式答案，甚至为有在的同类的复发的格用色子赌博。在这糊，根据 soluting 的原则代数学的方程，我们在场有二的 recuirnce 关系的一个班的答案的公式由 appling 索引重复和正式就职。与调制解调器计算工具解决 concerning 问题提供一个具体模型。

英文摘要：

It is very difficult, sometimes impossible, to get a formula solution of recurrence relation, even for the case of homogeneous recurrence with one indite. In this paper, according to the principle of soluting algebraic equation, we present the formula of solution for a class of recurrnce relations with two indices by appling iteration and induction. It provides a concrete model to solve the concerning problems with modern computing tools.
