摘　　要：提出了切伦科夫相关时间测量（ＣＣＴ）中初始粒子在辐射体里产生的δ电子的干扰问题，以及降低干扰的方法。通过模拟计算给出了北京－Ｃ工厂探测器初步设计中ＣＣＴ的π／Ｋ分辨本领。The interference effect from δ electrons created by primary particle passing through radiator in Cherenkov Correlated Timing (CCT) technique is discussed, and the possible method to diminish this interference effect is proposed. The capability for π/K separation is given by Monte Carlo simulation for CCT design of the Beijing Tau-Charm Factory.
