Abstract：
On the basis of particle identification methods at BES, this paper proposes a so-called relative likelihood method. The method makes the most use of the information provided by the BES, and apparently improves the particle identification efficiency with lower misidentification compared with the simple cut method. With this method, several studies in τ physics were done and good results have been obtained.
