摘要：

<正> We combine the tanh function method with the symmetry group method to construct new type of solutionsof Davey-Stewartson equation and implemente it in a computer algebraic system.As a result,some new types ofsolutions are obtained.This method is also applied to other differential equations if the nonlinear evolution equationsadmit nontrivial one-parameter group of transformation.
