摘　　要：利用多模辐射场广义非线性等幂次高次差压缩的一般理论 ,对第Ⅰ类两态叠加多模叠加态光场的等幂次N次方X压缩特性进行了详细研究 ,发现了其存在等幂次N次方X压缩效应的条件 ,还发现第Ⅰ、第Ⅱ两类两态叠加多模叠加态光场之间存在相似压缩和压缩简并现象 。By using of the general theory of generalized nonlinear equal power difference squeezing in multi mode radiation field,the property of equal power N th power X squeezing in the first kind of multi mode light field state of superposition state with distinguishable two quantum states is firstly studied in detail.It is found that conditions of the first kind of multi mode superposition state with distinguishable two quantum states mentioned above present equal power N th power X squeezing effect;and phenomena of similitude squeezing and degenerate squeezing in the between first and second kind of multi mode superposition state light field are found also.The results above show again that the state is kind of typical multi mode nonclsical light field
