SFL‑EAI‑02 Cellular Cycle Depletion and Electronic Component Aging: Unified Lifespan Model

Based on the unified SFL theoretical framework built in SFL-EAI-01, this paper deduces a general quantitative lifespan model. It verifies that cell cycle depletion in organisms and aging of electronic hardware comply with the same quota consumption rules. Combined with the state equation: G = G₀ + ΔG_d(+) − ΔG_d(−) and dissipation constraint: ε(T) = o(1/T) the fixed system quota Q determined by G₀ is defined, and the core lifespan formula L = Q / C is constructed. Aging is not random deterioration, but predictable irreversible consumption of innate quota under limited dissipation. This model achieves quantitative unification of biological aging research and electronic reliability engineering.
