| 摘 要： | Combing the ideas of FCT^1,2]with the MMOCAA^3],the ICT-MMOCAA difference method,in which the transport is corrected by interpolation,is established for convection diffusion problem in the paper,The new method possesses the property of general FCT schemes and it is free from oscillation,with which the large gradient problem is solved by the MMOCAA difference method based on high-order(≥2)Lagrange interpolation^3].Because the analysis in 3]is only suit for the scheme based on linear interpolation,the analysis method difered form 3] is used for obaining the error estimates of the new method.The numerical example is given in the paper.
