Basing on the future of fractal,this paper introduces the density analysis method and points out the defects of existing feature selection method based on fractal dimension.Then a feature selection method based on fractal and changes of neighborhood space density is proposed.

根据数据集的分形特征，引入了密度分析方法，指出了当前基于分形维数的属性选择方法的不足，提出了一种基于分形和邻接空间密度变化的属性选择方法。

Are also given by constructing Lyapunov function. Finally, by applying the energy methods, Sobolev embedding theorems and bootstrap arguments, the global existence of nonnegative classical solutions to equations with homogeneous Neumann boundary value condition is proved when the space dimension is at most 5. Under certain conditions for the coefficients of the reaction functions, the convergence of the solutions is established for the system with large diffusion coefficients by constructing Lyapunov function.
