摘要： In this paper,we discuss the hemogenization of boundary conditions for hyperbolic equations.Let the boundary I=d8 be represented as r=F₁UF₂Ur₃and Pinr₃=ø.We divide T₁into Pi and Ti for Ve>0 and give different boundary conditions on them.We discuss the behavior of solutions for some cases when certain measure of Pi goes to zero(as e→ 0).
