摘　　要：假设股票价格服从对数正态分布,利率是随机的,且股票价格的波动率,无风险利率均为时间的确定性连续函数,通过选取不同的计价单位及概率测度的变换,利用鞅的方法研究了随机利率下的可分离债券的定价,并得到了可分离债券的定价公式.This paper uses the Maztingale method to study the pricing of the bond with attached warrant under the stochastic interest rate and obtains the pricing formula of the bond with attached warrant by means of choosing different numeriare and changing the probability measure , Here supposes that the stock price follows a log-normal distribution, the interest rate is stochastic, the fluctuating rate of the stock price and the risk-free interest rate all are the definite continuous function of time.

关 键 词：可分离债券 等价鞅测度 计价单位 随机利率
