英文摘要In de Sitter space, de Sitter invariant special relativity can be established more or less parallel to the Einstein special relativity, based on the principle of special relativity and the postulate of two-universal constants. There are two kinds of simultaneity. One is the Beltrami-time simultaneity. By using the simultaneity, a new kind of inertial motion and a series of classical observables can be defined. In addition, the temperature of the horizon of de Sitter space for a set of inertial observers should be zero! Therefore, there is no need to explain the statistical origin of the entropy for the horizon of de Sitter space. Another is the proper-time simultaneity. With the proper-time simultaneity, the metric takes the Robertson-Walker-like form, which shows that the space has positive spatial curvature of order A. This has already been shown by the CMB power spectrum from WMAP and should be further confirmed in future. The existence of the two kinds of simultaneity also makes possible to explain the cosmic background or origin of inertial motion. Further, in de Sitter invariant special relativity, dynamics for a particle, including the pseudo-Hamiltonian mechanics, can be established. The non-relativistic limit of de Sitter invariant special relativity gives rise to the Newton-Hooke mechanics. The possibility of a test of de Sitter invariant special relativity is also studied tentatively. Finally, a kind of the doubly special relativity may be viewed as the de Sitter invariant special relativity in energy-momentum space.
