    "abstract": "It is proved in the manuscript that as long as the proper coordinate\ntransformation is introduced,, the equations of geodetic lines described in\ncurved space-time can be transformed into the dynamic equations in flat\nspace-time, that is to say, the Einstein theory of gravitation and other\ntheories based on the curved space-time can be identically transformed into\nflat space-time to describe. As an example, the Schwarzschild solution of the\nspherical symmetry gravitational field is transformed into flat space-time to\nstudy. The results show that there exists no any singularity in the all\nprocesses and the whole space-time including at the point r=0. So it seems more\nrational to discuss the problems of gravitation in flat space-time.",
