Abstract: The long‐time behaviour with a periodical boundary condition of semi‐discrete Kawachara equa‐tion in R1 has been studied in this paper .First ,the Crank‐Nicolson scheme has been used to discrete this equation to prove that such a semi‐discrete equation possesses a global arrtactor in H 5 ,then this global at‐tractor is actually a compact set of H5 . -
