摘要:本文提出一个基于双弦理论的统一框架,旨在为基本粒子的电荷与自旋属性提供第一性原理的起源解释。该理论认为,宇宙的基本实体由能量弦(构成能量与物质)与时空弦(构成时空几何背景)构成,二者通过“同频化驱动”机制动态耦合。在此框架下,粒子的电荷被诠释为其自旋运动在自身所“裹挟”的微小时空区域内,所激发的、一种稳定恒久的时空拓扑极化扰动(即电荷不在粒子本体上)。电荷的量子化数值由能量弦驻波模式的拓扑参数决定。同时,粒子的自旋起源于能量弦的闭环驻波(在形成闭环驻波前的频率振动和自旋自由度的自然激发行为)及其圆或非圆进动的几何动力学,其半整数量子化是时空拓扑约束的自然结果。本理论不仅自洽地推导出库仑定律、点粒子行为和德布罗意关系,还将电荷与自旋这两个基本属性统一于“时空拓扑动力学”的单一图景之下,为理解基本粒子的内禀性质提供了全新的几何化视角。 Abstract This paper proposes a unified framework based on the dual string theory, aiming to provide a first-principles explanation for the origin of the electric charge and spin properties of elementary particles. The theory posits that the fundamental entities of the universe consist of energy strings, which constitute energy and matter, and spacetime strings, which form the spacetime geometric background; these two types of strings are dynamically coupled via the mechanism of "frequency synchronization drive". Within this framework, the electric charge of a particle is interpreted as a stable and persistent topological polarization perturbation of spacetime, induced by the particle’s spin motion within the microscopic spacetime region it envelops (i.e., electric charge is not an attribute inherent to the particle itself). The quantized values of electric charge are determined by the topological parameters of the standing wave modes of energy strings. Meanwhile, the spin of a particle originates from the spontaneous excitation of frequency oscillations and spin degrees of freedom prior to the formation of closed-loop standing waves of energy strings, as well as the geometric dynamics of their circular or non-circular precession; its half-integer quantization is a natural consequence of the topological constraints of spacetime. This theory not only self-consistently derives Coulomb’s law, the point-particle behavior and the de Broglie relation, but also unifies the two fundamental properties of electric charge and spin within a single picture of "spacetime topological dynamics", thereby offering an entirely new geometric perspective for understanding the intrinsic properties of elementary particles.
