| 摘 要： | A discretespectral problem is discussed.and a hierarchy of integrable nonlinear lattice equations related to this spectral problem is devised.The new integrable symplectic map and finite-dimensional integrable systems are given by nonlinearization method.The binary Bargmann constraint gives rise to a Baecklund transformation for the resulting integrable lattice equations.
