# 重新认识固体热运动规律Re-Know the Laws of Thermal Motion of Solids

The limitations of the Debye internal energy function have been deeply analyzed, and the result indicates that “the Debye T3 law agrees with experiments in low temperatures” is an illusion. The analyzation reveals the general law of internal energy of solids and sketches its curve. It reaches some breakthrough viewpoints about the zero point energy and the characteristic temperature and provides practical means to determine both of them. It proposes that the vibration resilience of an atom comes not from interaction with its neighbor atoms but from inner itself, which means radius of atomic thermal-motion is getting bigger with temperature decreasing while it is getting smaller with temperature in-creasing. With temperature decreasing to absolute zero point, the harmonious vibration form of atomic thermal-motion changes into free particle in trap. Based on the fresh viewpoints, a new micro-structure model of solids is founded. These original viewpoints have important significances for both to know micro-structure and micro-motions of solids, and to change some existing notions; further more, these will serve as guidance for both to research the laws mi-cro-motion of solids (especially in low temperatures) and to yield some original theories to expand foundation theories of solid state physics.
