研究了特殊情况下平面上带有双侧吸收壁的随机行走模型,研究了母函数在这一随机行走模型中的应用,用母函数推导并证明了特殊情况下质点到达吸收壁的概率计算公式.
A special model of random walk with bilateral absorbent boundaries on the plane is studied, and the generating function is used in the model. By the generating function, the formula for computing the probability which the point reaches the absorbent boundaries in special case is presented.
