摘　　要：文章根据多模压缩态理论,对强度不等的非对称两态叠加多模叠加光场的等幂次N-H最小测不准态出现的条件进行了详细分析与讨论,从而得出:(1)在qN的积取偶数时,若各对应模的强度及初始相位都相等,态恒处于等幂次N-H最小测不准态;(2)当各对应模的强度和初始相位不等,但在一定条件下,态亦可处于等幂次N-H最小测不准态.Abstract： In this paper, by utilizing the theory of multi-squeezed states, the conditions of Equal-order N-H uncertainty state and Equal-order N-H minimum uncertainty state on multi-mode light field state of differ intensity of nonsymmetry superimpositions state with distinguishable two quantum states are studied. It finds out （1） when qN is even the intensity and the initial phase is all equal, the light field state always presents Equal-order N-H minimum uncertainty state; （2） the intensity and the initial phase are not equal, but under certain conditions, the light field state also presents Equal-order N-H minimum uncertainty state.
