A New Theoretical System Combinating Classical Mechanics and Quantum Mechanics

Replacing the potential energy of electromagnetic interactions in the original Schrödinger equation with the potential energy of gravitational interactions can lead to the Schr ö dinger equation of gravitational potential energy. It is a product of the combination of classical mechanics and quantum mechanics, suitable for describing macroscopic and microscopic systems. A quantum chemistry method that combines classical mechanics and quantum mechanics can be established. Multiple computational examples have been provided for applying this method. The established basic particle structure configuration of wave elements can explain the source of electron spin magnetic moments. These three facts constitute a new quantum mechanics theoretical system — a localized realism quantum mechanics system that combines classical mechanics with quantum forces. This has a positive impact on promoting the development of material structure theory and quantum theory
