文摘A new method is presented to generate finite dimensional integrable systems.Our starting point is a generalized Lax matrix instead of usual Lax pair.Then a unisonant r-matrix structure and a set of generalized Hamiltonian functions are constructed.It can be clearly seen that various constrained integrable Hows by nonlinearization method,such as the c-AKNS,c-MKdV,c~Toda,etc.,are derived from the reduction of this structure.Furthermore,some new integrable Hows are produced.
