Abstract
During the discussion of quantum mechanics and classical mechanics of the relationship, the key issue is the core of the general laws of quantum mechanics should be described as a macro-system. Observed at the macro system can not be linear superposition principle of quantum mechanics, quantum mechanics is the principle should be to find the bodies to make it disappear, and this is the role of each other and the environment caused by detuning, but there are special circumstances making phase coherent at the macro system can throw retained. In addition the nature of a purely quantum mechanics, such as the tunnel barrier, as well as phase coherence can exist at the macro system. In superconducting Josephson junctions to macroscopic quantum tunneling phenomenon appears, showing a macro-system nature of quantum mechanics to overcome the impact of the environment in order to bring significant benefits.
1, AB effect , AB effect by the process of development, and electric AB effect, the magnetic AB effect, the analysis of experimental programs.
2, the magnetic particles reflect the macro-quantum effect, from an analysis of three aspects, namely, macro-quantum effect of the magnetic elements of quantum magnets and macroscopic quantum tunneling effect, anti-hot iron particles and macroscopic quantum tunneling helps the quantum effect .
3, the strong-coupling superconductors, Josephson effect.
