摘　　要：研究不同光场的压缩效应,有助于人们深入认识光的本质。从振辐立方压缩的角度研究一般光场纯迭加态,并讨论获得最佳压缩的条件。结果表明,存在振辐立方压缩的纯迭加态的m数是有限的,其压缩情况必然随m、|α~2|与φ的不同而变化。It is helpful for realization of the essences of light to research the squeezing effect of different light fields. In this paper, the amplitude—cubic squeezing effect of general pure superposition states was studied and the optimum squeezing conditions were discussed. The results expressed that number of m of pure superposition states which exhibit the amplitude—cubic squeezing was limited and their squeezing cases were changed with different number of m. |a|~2 and φ.
