导出了二维浅水流动的涡动方程与速度环量的随体导数表达式，以此为基础，分析了二维浅水流动中旋涡的动力学性质；

The vorticity equation was first established and the characteristics of vortex motion in two-dimensional shallow-water flows was analyzed, and then discrete vortex method (DVM) was briefly described.

在随机微分方程的基础上，我们建立了金融市场模型，并且分析了模型的解与性质。

Using the stochastic theory to analyse the finance market model, we discuss the solution and properties of the model.
