用Fife量级求解eikonal方程

SOLVING EIKONAL EQUATION BY FIFE'S SCALING

应用Ｆｉｆｅ量级来讨论三维ｅｉｋｏｎａｌ方程．首先，将ｅｉｋｏｎａｌ方程放在Ｆｉｆｅ量级的框架内，得到回卷波解．其次，直接用Ｆｉｆｅ量级来摄动ｅｉｋｏｎａｌ方程，也得到类似的回卷波解．这两种不同方法得到的理论结果本质上一致，而且都在ＢＺ反应中实际观察到．

Abstract In this paper,the Fife's scaling is used to deal with the three dimensional eikonal equation.Firstly,we put the eikonal equation in the frame of the Fife scaling and obtain the expected scroll waves.Secondly,we directly use the Fife's scaling to perturb the eikonal equation and obtain the similar result.The results of two different methods are essentially the same and the patterns have been observed in the BZ reaction.
