摘要翻译：
本文研究了在快速振荡随机波动下零息债券的期限结构定价模型。分析了描述利率波动聚类的广义Cox-Ingersoll-Ross双因素模型的解。主要目的是导出债券价格关于代表随机波动过程快速尺度的奇异参数的渐近展开式。给出了双因子广义CIR模型解的二阶渐近展开式，并证明了展开式中的前两项与表示随机波动率的变量无关。

英文摘要：
In this paper we are interested in term structure models for pricing zero coupon bonds under rapidly oscillating stochastic volatility. We analyze solutions to the generalized Cox-Ingersoll-Ross two factors model describing clustering of interest rate volatilities. The main goal is to derive an asymptotic expansion of the bond price with respect to a singular parameter representing the fast scale for the stochastic volatility process. We derive the second order asymptotic expansion of a solution to the two factors generalized CIR model and we show that the first two terms in the expansion are independent of the variable representing stochastic volatility.
