摘　　要：当K-型五能级原子的两基态能级邻近简并时,连接基态的两个跃迁路径与同一个真空场辐射场相互作用导致的量子干涉效应便产生了空场诱导相干性。空场诱导相干性对K-型五能级原子系统的单光子和双光子电磁诱导透明有重要的影响。When the transitions connected by two nearly degenerate ground levels with an intermediate level in a five- level K-type atom interact with the same vacuum radiation field, between which the quantum interference leads to vacuuminduced coherence. We find that the vacuum-induced coherence make inportant effects on single-and two-photon transparency in the five-level K-type atomic system.
