New concept of quantum and its classical physics explanation

In this paper, the problems existing in the concepts of Planck's energy element and Einstein's light quantum are analyzed, and new concepts of quantum and electronic transition power are proposed. The new concept of quantum eliminates the inherent contradiction of the old quantum concept, and can explain the structure and spectral phenomena of hydrogen atom and photoelectric effect completely on the basis of classical physics without Bohr's "quantization hypothesis". The new concept of quantum breaks the gap between macro and micro, eliminates the contradiction between "classical physics" and "quantum mechanics", and lays an important foundation for the reconstruction of unified macro and micro physics.
