摘　　要：本文将背风波三层模式的理论应用于典型的背风波个例,判断了其解所属的类型,计算了这些个例的波长;指出当有多个波解存在时,最长波长所对应的波解是实际解;本文还用ARPS模式对这些个例作了数值模拟,模拟结果与解析解则有较好的一致性。In this paper,the lee-wave theories of three-layer model will be applied with several typical examples,which are judged to belong to what case,and are calculated the possible wavelengths. It is suggested that if there are several solutions of wavelengths, the longest one is the real solution of equation. Finally,the model ARPS is used to simulate these examples. Numerical solutions are accordant with the analyrical ones.
