摘　　要：In this paper,we propose a new non-Gaussian quantum state,termed the photon-modulated displaced thermal state(DTS).Using the operator ordering method,we obtain the normal ordering product of its density operator and then investigate its normalization,the negativity of its Wigner function and its non-Gaussianity.
