Abstract	For study of high-redshift galaxies, Lya observation is crucial. Strong Lya emission observed from high-redshift galaxies is problem, because of large optical depth for Lya. Neufeld(1991) shows that assumption of multiphase structure (cloud and intercloud medium) permits higher escape fraction. However he neglects effect of internal motion of cloud. I will talk about Neufeld model, and results of my simulation with assumption of internal motion of dusty cloud.
Keywords	Lyman series, absorption, scattering
