摘　　要：利用多模压缩态理论,研究了态|Ψ(f3)>q中广义磁场分量的不等幂次高次和(H)压缩特性。结果表明:在一定的条件下,态|Ψ(f3)>q的广义磁场分量可呈现出周期性变化的不等幂次高次H压缩效应;光场的经典振幅和经典初始相位的任意非对称空间分布特征对其压缩程度和压缩深度等压缩特性将产生直接的影响。The properties of non - equal - power higher- power sum - squeezing （H - squeezing） of generalized magnetic field component of the state ｜ψf^（3）〉q is studied firstly by utilizing the multimode squeezed state theory . It is shown that under a series of fixed conditions, the generalized magnetic - field component of the state ｜ψf^（3）〉q can display the effect of generalized nonlinear non - equal - power higher - power H - squeezing which changes periodically and alternatively; and the any asymmetrical spatial distribution of the classical amplitude and classical phase of light - field in the state I ｜ψf^（3）〉q would have a direct influence upon the squeezed degree and squeezed depth of non - equal - power higher- power H - squeezing present by the generalized magnetic - field component in the state ｜ψf^（3）〉q
