中文摘要
众所周知,经典的对流扩散方程不能很好地描述污染物在土壤等非均质介质中的扩散过程,对于维护环境安全的实际方法,我们研究了连续时间随机游走作为微观模型和分数阶扩散方程作为宏观模型。我们的研究成果如下:(1)我们将连续时间随机游走模型和分数阶扩散方程模型联系起来,并在此基础上提出了更好的模型。(2)数学分析,如解的唯一性和渐近性等。(3)污染源反问题的数学分析和数值方法。
英文摘要
It is known that the classical advection-diffusion equation is not an adequate model for diffusion processs of contaminants in heterogenous media such as soil.For real methods for keeping the environmental safety, we have studied the con-tinuous-time random walk as microscopic model and the fractional diffusion quation as macroscopic model. Our achievements are as follows: (1) We relate both models: the continuous-time random walk and the fractional diffusion quation, and derive other from another, and we propose better models on the basis of such studies. (2) Mathematical analysis such as the unique existence of solution and the asymptotic behavior. (3) Mathematical analysis and numerical methods for inverse contamination sourceproblems.
