通过构建微分方程计算出Vasicek-Ornstein—Uhlenbeck(VOU)过程的”阶原点距,并利用其各阶原点距给出VOU过程的拉普拉斯变换和特征函数.
By the method of constructing differential equations, the moments of Vasicek-Ornstein-Uhlenbeck process are calculated, and finally the Laplace transform and the characteristic function are given by virtue of the moments of Vasicek-Omstein-Uhlenbeck process.
