摘　　要：把Ｗｈｉｔｆｉｅｌｄ提出的哈密顿量推广到声学激子，通过激子和声学声子相互作用，导出了有效哈密顿量．研究慢速激子引起线晶格畸变时对激子基态能量及有效质量的影响．In this paper authors extend the Hamiltonian proposed by whitfield to the acousticexcitons. Using the variational method via the interations betWeen the deformation potential and acoustic phonons the authors derive the effective Hamiltionian. The properties of the acoustic excitonsin linear crystal lattices are also discussed.
