Deterministic Mechanism of Wave-Particle Duality Based on Medium Circulation and Angular Momentum Conservation

Aiming at the core problems of traditional quantum mechanics, such as the lack of physical mechanism in probabilistic interpretation, untraceable wave function collapse, and metaphysical observation effect, this paper establishes a deterministic physical model of wave-particle duality based on the Medium circulation theory, the first principle of global angular momentum conservation, combined with nearly spherical particle entity, orthogonal double-elliptic flow velocity topology, and fine-structure geometric constant . It is clarified that the particle nature originates from the spherical local vortex entity, and the wave nature originates from the vacuum angular momentum wave field excited by the internal double-elliptic circulation. The medium propagation resistance formulas of particle state and wave state are derived, and the modulation mechanism of geometric constant on dual-state characteristics is quantified. The essence of observation behavior is revealed as exogenous angular momentum perturbation coupling, which completely explains the wave field collapse and dual-state switching caused by observation. The whole process conforms to the law of angular momentum conservation, abandons the traditional probabilistic interpretation, and constructs a causally complete and mathematically self-consistent underlying physical system for wave-particle duality.
