中文摘要	Based on the Beltrami-de Sitter spacetime, we present the Newton Hooke model under the Newton Hooke contraction of the BdS spacetime with respect to the transformation group, algebra and geometry. It is shown that in Newton Hooke space time, there are inertial-type coordinate systems and inertial-type observers, which move along straight lines with uniform velocity. And they are invariant under the Newton Hooke group. In order to determine uniquely the Newton Hooke limit, we propose the Galilei-Hooke's relativity principle as well as the postulate on Newton Hooke universal time. All results are readily extended to the Newton Hooke model as a contraction of Beltrami-anti-de Sitter spacetime with negative cosmological constant.
