A method to construct the finite-band solution to the soliton equation is presented. We take the Jaulent-Miodek equation as an example. With the use of the nonlinearization of Lax pair, the Jaulent-Miodek equation is decomposed into two finite-dimensional integrable systems, whose properties are studied from the view of an r-matrix. Then through solving these finite-dimensional integrable systems, the finite-band solution of the Jaulent-Miodek equation is obtained. (C) 1997 American Institute of Physics.
