New Understandings of Quantum Mechanics Based on Interaction

Abstract

The interaction between two parts in a compound quantum system may be reconsidered more completely than before and some new understandings and conclusions different from current quantum mechanics are obtained, including the conservation law in the evolution in an isolated quantum system, new understandings of duality of particle and wave and the superposition principle of states, three laws corresponding to Newton's laws, new understandings of measurement and the uncertainty relation, arguments against the non-locality of any entangled state and a simple criterion of coherence which is obtained for the experimenter to examine the correctness of the non-locality. These may make quantum mechanics be easily understood intuitively and some strange properties will not appear.
