Most physicists are dissatisfied with the current explanation of quantum mechanics, and the movement of the microscopic particles always confuses most physicists. Lots of people want to find a method to solve this question. However this question cannot be solved perfectly up to now. In this paper, the annihilation generation movement (AGM) is developed according to the electron motion in hydrogen atom. To verify the AGM, a curved surface to fit the dark fringe of the single slit diffraction is proposed. Based on the AGM, the wave function of a free electron is rewritten and the double-slit experiment can be understood. Here, we show the AGM is a perfect physical image to solve the puzzles of quantum mechanics, such as the understanding of Heisenberg's uncertainty principle and the steady-state transition. We anticipate that we can find a new way to explain the quantum mechanics based on the AGM.
