摘　　要：对于一种形式的纠缠相干态,通过引入正交基矢,变为分立形式,然后用concurrence方法计算了其纠缠度,同时利用算符起伏和Mandel因子Q研究了其非经典效应(压缩效应、反聚束效应).研究发现,纠缠总是与反聚束效应相对应,反聚束效应越大,纠缠越大.For a kind of entangled coherent states, by introducing orthogoral basis, they are converted to discrete ones. Their entanglement are calculated by Concurrencel, and their nonclassical effects, such as squeezing and antibundhing are caulated by operators variance and mandel factor. It is found that the entanglement always corresponds with antiquating and the larger antiquating is, the stronger entanglement is.

关 键 词：纠缠相干态 反聚束效应 CONCURRENCE
