Based on an ordinary differential equation which possesses doubly-periodic solut ions, a new method for constructing doubly-periodic solutions for differential e quations and its algorithm are proposed. This method can be carried out in compu ter by the aid of symbolic computation. A lot of new exact solutions of the nonl inear coupled scalar field equations are found by using this method.
