The classical model of spinning particle is analyzed in details in two versions - with single spinor and two spinors put on the trajectory. Equations of motion of the first version are easily solvable. The system with two spinors becomes non-linear. Nevertheless the equations of motion are analyzed in details and solved numerically. In either case the trajectories are ilustrated and their properties are disussed. There is also discussion of possible physical quantities associated with the spinning motions. Among others: the size of particles and their gyromagnetic ratios. Finally, some possible, speculative explanations of the properties of the Universe are proposed: the origin and nature of dark matter and lack of the equilibrium bettween mater and anti-matter.

旋转粒子——经典描述

经典的自旋粒子模型有两个版本进行了详细分析——单个旋量和两个置于轨道上的旋量。第一个版本的运动方程很容易求解。具有两个旋量的系统变得非线性。尽管如此，仍详细分析了运动方程并进行了数值求解。在任何一种情况下，都说明了轨迹，并讨论了它们的特性。还讨论了与旋转运动相关的可能物理量。其中包括：粒子的大小及其旋磁比。最后，提出了对宇宙特性的一些可能的推测性解释：暗物质的起源和性质以及物质和反物质之间缺乏平衡。
