摘　　要：本文利用量子力学迭加原理,讨论了相干态与Fork态的迭加产生的压缩和反聚束效应.结果表明在一些迭加态中存在两个压缩区,两个压缩区之问的区域反聚束效应较强,压缩效应及反聚束效应的强弱与相干态的平均光子数|α|~2及Fork态|m>的光子数m密切相关.文章最后一节讨论了在实验室如何实现这一压缩迭加态.This paper is discussed superposition of coherent states and squeezed states caused the squeezing and the antibunching efect by a simple implemention of the superposition principe of quantum mechanics. The result showed some superposition states have two squeezed regions Region between two squeezed regions has stronger antibunching efect, The squeezing and the antibunching efect exhibiting in the superposition states closely depend on the avarage photon number |α|2 of the coherent states and the photon number m of the Fork states |m>. Finally 9 we discuss how such states can be generated in the laboratory.
