Quantization Principles Based on the Shielding Effect and Planck’s Constant in Gravitational Fields

To reveal the physical nature of Planck’s constant, an analytic expression of Planck's constant is presented, and based on this expression, the De Broglie’s relation and the expression of momentum operator are derived. To calculate Planck’s constant, the shielding effect of the fundamental interaction is introduced, and found that Planck’s constant can be calculated for the fundamental interaction fields with shielding effects, thus have obtained the general quantization principle: the systems with shielding effects can be quantized. As a result, the representation of Planck's constant in the gravitational field is derived, indicating that although the gravitational field can’t be quantified, which has effects on quantum phenomena through expressing Planck’s constant based on the curvature of space-time. This work is of significance for deepening the understanding of quantum mechanics, and for exploring the quantum mechanism in the cosmic celestial bodies.
