We obtain that i ) with the increase of the phonon - pseudospin interaction and the thickness of the superlattice , the phase transition temperature of the superlattice will increase . ii ) the increase of the phonon - pseudospin interaction leads to the change of the number of the pyroelectric peaks in the temperature curve of pyroelectric coefficient and to the change of the pyroelectric coefficient 研究发现，声子与赝自旋的相互作用会影响铁电超晶格热电峰的数目以及热电系数的温度曲线的形态，而且声子与赝自旋耦合作用的增强以及超晶格尺寸的增大都会使整个材料的相变温度增加。
