摘　　要：A direct method for obtaining the expanding integrable models of the hierarchies of evolution equations was proposed. By using the equivalent transformation between the matrices, a new isospectral problem was directly established according to the known isospectral problem, which can be used to obtain the expanding integrable model of the known hierarchy.A direct method for obtaining the expanding integrable models of the hierarchies of evolution equations was proposed.
