英文摘要	The application of the de/dx method for e/pi identification of the measurement of the mass of tau heavy lepton by beijing spectrometer (bes) operated at beijing electron positron collider (bepc) is described. with additional de/dx information, the efficiency of selecting the emu events from tau+tau- is increased more than three-fold compared to that with traditional e/pi identification by electromagnetic shower measurement alone. this results in not only reduction of the loss of the emu events in off-line selection, but also in a 75% reduction of the amount of the time needed to run the bes/bepc for data collection and computer cpu time for data off-line processing for selecting the same number of tau+tau- events.
