The Absorbing Probability Generating Functions at nth Step for a Class of Correlated Random Walks

首先得到了随机点在一步和两步游动下被三条吸收壁吸收概率的一般表达式，并进行了数学证明。

Firstly we give the computing formulae of the probabilities that the random point at original point is absorbed by the three absorbent boundaries in one or two pace random walk .

定义并讨论了具有吸收壁的一类相关随机游动，并利用母函数的方法导出了在第n步被吸收的概率母函数表达式、最终吸收的概率及期望持续时间的明显表达式等。
