摘　　要：根据量子力学中的线性叠加原理,用多模虚奇相干态和多模复共轭偶相干态组成了特殊的四态叠加多模叠加态光场 ,运用多模压缩态理论得到了的等N次幂Y压缩的一般理论结果,通过对这一理论结果的数值分析发现:当压缩幂次N,腔模总数q,各模相干态的平均光子数Rj2,以及奇相干态和多模复共轭偶相干态叠加几率幅的模r0、re等参量的取值满足一定的条件时态 可呈现:a.等幂次N-Y最小测不准态;b.“半相干态效应”;c.半压缩效应;d.第一正交分量呈现等N次幂Y压缩或第二正交分量呈现等N次幂Y压缩.According to the linear superposition principle mechanics,the four-state superposition multi -mode superposition state light fidle is composed by multi -mode imaginary odd and complexconjugation coherent states,and its general results of N-th power Y squeezing are got out by the multi-mode squeezing state theory by numeric analying,it is found that:when parameters squeezng order N, total number of multi -modeq,average photon numbers of every mode Rj2 and modules of superposition probability amplitudes r0(re)are take different values,the state will represents: a.the equal-order N-Y minimum uncertainty states b. half coherent states effect c.the first and second orthometric component represent N-th power Y squeezing d. half-squeezing state.
