The theatrical foundation of this paper is option pricing model. This paper focuses on the Black-Scholes model, details the basic postulation, principle and pricing formula. And it is pointed out that the postulation that volatility is constant can't reflect the varying market volatility. Violation of this postulation will lead to biased pricing results.

期权定价模型是本文分析的理论基础,文中以Black-Scholes模型为主,分析了期权定价模型的基本假设、原理与定价公式,指出波动率为常数的假设不能反映市场波动率的变化状况,对该假设的违背将使定价结果产生偏差,因此,波动率在期权定价中有重要的作用。

The time space regularity of overlying strata movement and damage induced by coal mining was studied using the dynamic mechanics model. The developing regularty of faults and bed separation as well as surface subsidence caused by mining was analyzed based on the geological and mining conditions of working face 5306 in Xinglongzhuang Coal Mine. The data explaination using the model is more reasonable than that using other models. So it can be used in practical mining activities.
