摘　　要：计算了奇偶相干态的测不准关系,并讨论了它们的非经典性质,特别是偶相干态的非经典性质.偶相干态在一定区域内呈现压缩效应,而奇相干态没有这种性质.In this paper, we calculate the uncertain relation of even and odd coherent state and discuss about their non-classical property, especially that of even coherent state. Even coherent state shows squeezing effect at some certain places, but odd coherent state has no this property.

关 键 词：奇偶相干态 非经典性 测不准关系
