Based on the coupled mode theory, second harmonic generation ( SHG) in the form of Cherenkov radiation from a channel waveguide has been investigated taking the propagation loss into account.

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.

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。
