A new kind of the mathematical discription of fines deposition, release and migration in porous media was formulated. So, a new mathematical tool was given for the quantitative discription of the injectivity decline due to the fines problem.

与现存理论相比，本文提出的数学模型具有如下方面的特点： 1、由于直接从微粒在孔隙内的动力学特征出发，因此，模型中需要由实验确定的模型参数较少，同时，模型中不出现由实验确定的经验的关系式。

This dissertation focuses on the vector stochastic integral and its applicationsto mathematical finance. We first conduct a comprehensive study on VSI and provide aneconomical justification on the question of why VSI is more suitable than the component-wise stochastic integral for mathematical finance.

本论文以向量随机积分为主线，首先较为系统地研究了向量随机积分，给出了在金融数学中使用向量随机积分较之使用按分量的随机积分更合理的经济学解释。
