摘要：

The authors study a one-dimensional non-linear lattice with two sites per unit cell, placed respectively in a double-quadratic and a parabolic substrate potential. The phonon stability and phase diagram of this structure which can represent a possible model of some hydrogen-bonded diatomic chains are determined and some special features of the model are found.
