摘　　要：Topological phonon is a new frontier in the field of topological materials.Different from electronic structures,phonons are bosons and most topological phonons are metallic form.Previous studies about topological phonon states were focused on three-dimensional(3D)materials.

关 键 词：materials. form. TOPOLOGICAL
