英文摘要：
In the present work, we propose a new multifactor stochastic volatility model in which slow factor of volatility is approximated by a parabolic arc. We retain ourselves to the perturbation technique to obtain approximate expression for European option prices. We introduce the notion of modified Black-Scholes price. We obtain a simplified expression for European option price which is perturbed around the modified Black-Scholes price and have also obtained the expression of modified price in terms of Black-Scholes price.

中文摘要：
在本文中，我们提出了一个新的多因素随机波动率模型，其中波动率的慢因子用抛物线近似。我们继续使用微扰技术来获得欧式期权价格的近似表达式。我们引入了修正Black-Scholes价格的概念。我们得到了受修正Black-Scholes价格扰动的欧式期权价格的简化表达式，并且还得到了修正价格在Black-Scholes价格方面的表达式。
