摘要：

In view of the importance of the role of host lattice on the proton configurations in hydrogen-bonded crystals, a cluster theory is developed to explain the phase transition in one-dimensional ferroelectrics PbHPO4. The correlation between the spontaneous polarization and Pb-PO4 translational mode frequency is analyzed on the basis of a pseudo-spin model for the proton system. It is shown that rather high transition temperature T(c) in this system is related with the large anisotropy among proton-proton correlations and the renormalization of the host lattice into proton system.
