摘    要:We find a new x-parameter squeezed coherent state (p, q)κ representation, which possesses well-behaved features, i.e., its Wigner function's marginal distribution in the "q-direction" and in the "p-direction" is the Gauss/an form exp(-κ(q' - q)2}, and exp{(p' - p)2/κ}, respectively. Based on this, the Husimi function of(p, q)κ is also obtained, which is a Gauss/an broaden version of the Wigner function. The (P, q)κ state provides a good representative space for studying various properties ot the Husimi operator.
