摘要
全文介绍了差分方程的概念,并给出了一阶差分方程xn+1=axn+b的通解与给定初始条件x1=c的特解,同时又给出了二阶差分方程xn+2=axn+1+bxn的通解与给定初始条件x1=m1,x2=m2的特解,并详细讨论了这两种差分方程在概率论中的应用。
This paper first introduces the concept of difference equation and presents the ordinary solution of first order difference equation xn＋1=axn＋b and the special solution of the provided initial condition x1=c.Then it offers the ordinary solution of second order difference equation xn＋2=axn＋1＋bxn and the special solution of the provided initial condition x1=m1,x2=m2.Finally it gives a detailed discussion to their application in probability theory.
