According to the linear superposition principle of state in quantum mechanics,the four-state superposition multimode entangled state (4SMES) light field is constructed,that is composed of multi-mode vacuum state,multimode coherent state and its contrary state,multimode imaginary coherent state. Then the multimode squeezed state theory is utilized to study the characteristics of generalized nonlinear equal-power higher-power sum squeezing of the generalized electric-field component in the vacuum state immiting 4SMES light field mentioned above in detail.It is found that the vacuum state immiting 4SMES light field is a type of four-state superposition multimode nonclassical light field,and under certain fixed conditions,the generalized electric-field component in the 4SMES light field can display generalized nonlinear equal-power 4m+2-th power sum squeezing effects which change periodically.
