摘　　要：本文在文献[3]的基础上,利用多模不等幂次压缩理论[7]研究了第Ⅱ类两态叠加多模叠加态光场　　　　　的不等幂次Nj次方H压缩效应。结果发现:当各模的压缩幂次数之和为偶数时,态　　　恒处于不等幂次Nj-H最小测不准态;而当各模的压缩幂次数之和为奇数时,态　　在一定条件下总可呈现出周期性变化的Nj次方H压缩效应;文献[3]的研究结果,仅仅只是本文的普遍性结果在Nj=N（j=1,2,3,……,q）这一条件下的特例。On the basis of reference [3], the paper probes the squeezing effects of unequal-power higher-power H-squeezing in the second king of multimode superposition state light field with the superposition of two quantum state by using the definition of multimode squeezing. It is found that when the sum of the squeezing power of each mode is even number, the state is always in Nj- H minimum uncertainty state; when the sum of the squeezing powers of eachmode is odd number, under some certain conditions the state , can also present Nj-th power H-squeezing that changes periodically; the result of reference [3] is only a particular example under the certain condition Nj = N of this paper's universal result.
