The spueezing properties in a new kind of even and odd nonlinear coherent states are discussed via the measurement phase operators introduced by Barnett S M and Pegg D T. It is found that there are only a kind of CS squeezing but there are not CN and SN squeezing. Using the numerical calculation, we studied the squeezing properties of CS. It is shown that the CS squeezing properties of the even and odd nonlinear coherent states are different from those of usual even and odd coherent states. Squeezing exists for the new even nonlinear coherent states in the wide range, while small range for the new odd nonlinear coherent states.
