| 英文摘要 | A novel method for obtaining the approximate symmetry of a partial differential equation with a small parameter is introduced. by expanding the independent variable and the dependent variable in the small parameter series, we obtain more affluent approximate symmetries. the method is applied to two perturbed nonlinear partial differential equations and new approximate solutions are derived. |
