Complete System of Unified Field Equations for Four Fundamental Forces

Aiming at the core problems of traditional four-force unification theory, such as dimensional mismatch, lack of degrees of freedom in spacetime curvature, insufficient explanation of light speed invariance, and inability to accurately match the magnitude gap of the four forces, this paper constructs a complete and self-consistent system of four-force unified field equations based on first-principle axioms such as vacuum medium circulation, global zero angular momentum conservation, and sphere-ellipse nested particle topology. By introducing the natural unit restoration mechanism, anisotropic projection operator, vacuum wave excitation threshold locking mechanism, and topological nested double exponential decay mechanism, the logical gaps and mathematical loopholes of the original theory are filled, realizing the global mathematical unification of gravitation, electromagnetism, strong nuclear force, and weak nuclear force. This paper presents a complete set of directly observable equations in plain text (including axiom-based fundamental equations, revised equations, and coupled total equations), all formulas are marked with standardized numbers, and the full text adopts a Chinese-English bilingual comparison format, which balances academic rigor and document compatibility and can be directly used for academic submission and theoretical demonstration.
