摘要
This paper proposes PML absorbing boundary based on Cerjan attenuation function based on the study of Cerjan absorbing boundary and PML absorbing boundary.Wave field modeling calculations by using two absorbing boundary conditions show that PML absorbing boundary based on Cerjan attenuation function can perform absorption much more clearly and absorb the boundary reflection from various angles.It is suitable to seismic wave numerical modeling in two-dimensional situation.
