摘　　要：建立了有限分形介质中带有分数阶振子的分数阶反应扩散方程,利用Laplace变换和有限Hankel变换及相应的逆变换,给出上述问题浓度分布的解析解并以广义Mittag-Leffler的形式给予表示。将二维,三维空间以及整数阶的有限分形介质中反应扩散的模型作为本文的特例进行讨论。The fractional reaction-diffusion differential equation with a fractional oscillator in a finite fractal medium was established. By applying Laplace transformation, the finite Hankel transformation and their inverse transform, the exact solution of the model were obtained. The expression in the form of the generalized Mittag-Leffler function was given. Finally, the solutions of twodimensional space, three-dimensional space and the integral diffusion equation as some particular eases of this paper were discussed.
