| 摘要: |
| 这项工作是详细研究北京谱仪(BES)轻子识别的一部分。本文报告了π/μ、π/e 分辨的Monte Carlo结果。结果表明：在北京谱仪中π/μ分辨有两个有效的截断，即位置与方向。对于π/e分辨也有两个有效的截断，即总电荷量沉积和二极矩。 |

| Abstract: |
| This work is one of the series，which studies the lepton identification in the BES (Beijing Spectrometer) in detail. The preliminary M.C. results about the discrimination between muon，electron and the other secondaries generated by hadron punch-through，especially by pion，are reported. The results show that there are two efficient cuts，i.e. the total charge Q and the second moment S for the discriminating of electron and pionin barrel shower counter，and there are also two cuts，i.e. position for direction for the discriminating of muon and pion in muon-system of BES. Thus the BES is of the good ability for the lepton identification. |
