                                                        ABSTRACT: The paper was based on the definition of time-rate, and founded the general transformation between reference systems that background had different standard of time, and the self-consistent theoretical system has been formed to promote the classical electrodynamics. According to the principle, more discussion about the relationship between structure of time-rate in space and physical properties in its own area (gravity, centrifugal force, acceleration system) was presented. In view of the above, the paper expounded the role of macro mechanism of gravity and inertia force, and unified them finally. The possibility of tremendous instantaneous acceleration has been put forward.
