Abstract The decays of J/φ→μ+μ- and J/φ→ e+e- are studied by Monte-Carlo simulation, based on the Beijing Spectrometer (BES)Ⅲ offline software system. The methods of determination of the J/φ event number via J/φ→μ+μ- and J/φ→ e+e- are presented, respectively. These methods can be used to determine the J/φevent number for the coming BESⅢ J/φ data sample.
