【Abstract】 The variate-separating method and adding variate-separating method usually used in solving partial differential equation systems have some limit and some special equation systems need special method. In this paper, a new variate-separating method is proposed for solving a special kind of strong non-linear partial differential equations. This method, while solving the special equation systems, has some arbitrary functions, and thus gives out infinite possible solutions that correspond to infinite boundary conditions. These solutions have different meanings for different actual problems. This metod plays some parts in the study of numerical solution of partial differential equation systems.更多还原
