量子力学（Quantum Mechanics)是研究微观粒子的运动规律的物理学分支学科，它主要研究原子、分子、凝聚态物质，以及原子核和基本粒子的结构、性质的基础理论，它与相对论一起构成了现代物理学的理论基础。量子力学不仅是近代物理学的基础理论之一，而且在化学等有关学科和许多近代技术中也得到了广泛的应用。-Quantum mechanics (Quantum Mechanics) is a branch of physics disciplines of the law of motion of microscopic particles, it is mainly to study the structure of atoms, molecules, condensed matter and atomic nuclei and elementary particles, the basic theory of nature, together with the theory of relativity constitutes a modern the theoretical basis of physics. Quantum mechanics is not only one of the basic theory of modern physics, but also in the related disciplines of chemistry and modern technology has been widely used.
