摘　　要：Using the Monte Carlo samples of about 800 pb^-1 and 500 pb^-1 generated at and around 3.773 GeV with BOSS （BESⅢ Offtine Software System） 6.0.2 and BOSS 6.1.0, we have studied the branching fractions for D^0 → K^-l^＋vl and D^0 →π^- l^＋ vl （l=e, μ）. According to the simulation results, the expected precision of these measurements for 20fb^-1 ψ（3770） data which will be collected on BESⅢ are well estimated.Using the Monte Carlo samples of about 800 pb^-1 and 500 pb^-1 generated at and around 3.773 GeV with BOSS （BESⅢ Offtine Software System） 6.0.2 and BOSS 6.1.0, we have studied the branching fractions for D^0 → K^-l^＋vl and D^0 →π^- l^＋ vl （l=e, μ）.
