摘　　要：利用新近建立的多模压缩态理论,研究了由多模复共轭虚相干态、多模复共轭虚相干态的相以态和多模复共轭相干态的线性叠加组成的一种新型的三态叠加多模叠加态光场|Ψ(3)〉q中广义磁场分量的等幂次N次方Y压缩特性.结果发现,在一定条件下,态|Ψ(3)〉q的广义磁场分量可呈现出周期性变化的、偶数次的广义非线性等幂次N次方Y压缩效应.By utilizing the theory of multimode squeezed states established recently, the generalized nonlinear even number power equal-power N-th power Y-squeezing effects of generalized magnetic-field component in the new kind of multimode quantum light-field state (｜Ψ^((3))〉_q) is studied firstly in detail, which is composed of the linear superposition of macroscopically distinct three quantum states named multimode complex conjugation imaginary coherent state, the contrary state of multimode complex conjugation imaginary coherent state and multimode complex conjugation coherent state. It is found that under certain and fixed conditions, the generalized magnetic-field component in the state ｜Ψ^((3))〉_q can always display the effects of even number power generalized nonlinear equal-power N-th power Y-squeezing.
