摘要
得到了局部鞅经解析函数复合后所具有的一个性质.作为应用，利用该性质并借助二维Brown运动的常返性，给出了代数学基本定理的一个概率证明.
In this paper,a property of the local martingles acted on by an analytic function is obtained. As an application, using this property and with the help of the recurrence of two-dimensional Brown motions, the fundamental theorem of algebra is shown by means of the method of probobility.
