摘要：文章提出了一种求解n维时间分数阶对流扩散方程的离散格式.首先基于差分公式得到了所研究方程的时间离散格式,其次证明了所得格式的稳定性,最后分析了格式的收敛性并得到格式的收敛阶为O(τ2-α).%In this paper,a discrete scheme is proposed for solving the n-dimensional time fractional convection-diffusion equation.The paper is organized as follows.Firstly,we obtain a time discrete scheme based on difference formula.Secondly,we prove that the time discrete scheme is unconditional stable.Finally,the convergence of the scheme is discussed and the convergence order is O(τ 2-α).
