摘　　要：Using the undetermined coefficient method, Holly-Preissmann scheme isimproved effectively. The scheme with the minus velocity is added, and a new conservative scheme isalso presented on the basis of original scheme. The simulations of the new scheme accord with theexact result, which enhances its applicability in the engineering.Using the undetermined coefficient method, Holly-Preissmann scheme isimproved effectively.
