This is an originative physics experiment. The experiment firstly adopts multi-source system. It bases on the fact that moving clock slow-down effec. By comparing the relative change of frequency which relative moving clocks, the characteristic of space can be measured in diferent directiones. Through untiring hard work of ten years, we had comprehensively measured the difference that clocks moving in different direction. Is the clock that eastward moving consistent with that westward moving? Does the electric-fieldWhat and magnetic-field effect the clocks? Does the acceleration affect the clocks? Is the one-way speed of light equal in any direction?¡. all these questions have been answered exactly by the experiment.
In the end of the thesis, we discuss the gravitational field. Is the mass invariable in the gravitational field? How the ruler and the clock change in the gravitational field? Why is there some diverge on the speed of light in the gravitational field? What does mean the curved space? Why does quantizationthe in micro world? ¡ By comprehensive analysis of present physics facts, we present the inference that mass will change with the change of height in gravitational field, that is ¡°mass-field equation¡±. It can solve the correlative questions about gravitational field. This theoretical system is brief and is clearer than general relativity. Moreover, it can have some breakthrough than general relativity.
