<正> Using the variable separation approach,we obtain a general exact solution with arbitrary variable separationfunctions for the (2+1)-dimensional breaking soliton system.By introducing Jacobi elliptic functions in the seed solution,two families of doubly periodic propagating wave patterns are derived.We investigate these periodic wave solutions withdifferent modulus m selections,many important and interesting properties are revealed.The interaction of Jabcobielliptic function waves are graphically considered and found to be nonelastic.
