摘　　要：利用多模压缩态理论 ,研究了一种新型的三态叠加多模量子叠加态光场 ｜Ψ( 3 ) 〉q 中广义电场分量的等幂次N次方H压缩特性。结果发现 ,在一定条件下 ,态 ｜Ψ( 3 ) 〉q 的广义电场分量总可呈现出周期性变化的广义非线性等幂次 N次方H压缩效应。By utilizing the theory of multimode squeezed states estabilshed recently, the generalized nonlinear equal-power N-th power H-squeezing properties of generalized electric-field component in the new kind of three state superposition multimode quantum superposition state light field ｜Ψ^((3))〉_q is studied firstly in detail. It is found that under certain and fixed conditions, the generalized electric-field component in the state (｜Ψ^((3))〉_q ) can always display the effects of generalized nonlinear equal-power N-th power H-squeezing which changes periodically.
