The equal-order Y-squeezing effects of photon-added pair coherent state and photon-subtracted pair coherent state are studied numerically.It is shown that the photon field can exhibit the equal-order K-th power Y-squeezing effects,but when photons are added to mode a of a pair coherent state or subtracted from mode b of a pair coherent state,i.e.as the number of photon pair m increases,the equal-order K-th power Y-squeezing effects of these two states both decrease with the similar trend.
