引入一种坐标概率密度分布介于高斯分布和矩形分布之间的量子力学纯态——超高斯纯态.研究了这种态的某些量子力学性质、压缩和高阶压缩以及Shannon熵等，并讨论了Shannon熵与压缩的关系.We introduce a kind of quantum pure statessupergaussan pure states, in which the coordinate probability density distribution is between the gaussian distribution and rectangle distribution. Some properties of quantum mechanics, squeezing, higher-order squeezing and Shannon's entropy in this state are studied. The relation between squeezing and Shannon's entropy is also discussed.
