研究了谐振腔内具有双能级系统的一维耦合谐振腔波导与相应环境相互作用所引起的退相干现象。每个环境都被建模为谐振子的连续体。通过求出混合系统的本征态，即混合系统的修饰态，计算了一个激发的寿命，它表征了这种混合系统中量子相干性的存在和基本的量子性质。
Decoherence for a one-dimensional coupled-resonator waveguide with a two-level system inside one of the resonators, induced by their interaction with corresponding environments, is investigated. Each environment is modeled as a continuum of harmonic oscillators. By finding the eigenstates of the hybrid system, which is the dressed state of the hybrid system, we calculate the lifetime of one excitation, which characterizes the existence of quantum coherence in such hybrid systems and the basic quantum nature.
