    "abstract": "Classical model S_{Dcl} of the Dirac particle S_D is constructed. S_D is the\ndynamic system described by the Dirac equation. For investigation of S_D and\nconstruction of S_{Dcl} one uses a new dynamic method: dynamic disquantization.\nThis relativistic purely dynamic procedure does not use principles of quantum\nmechanics. The obtained classical analog S_{Dcl} is described by a system of\nordinary differential equations, containing the quantum constant $\\hbar$ as a\nparameter. Dynamic equations for S_{Dcl} are determined by the Dirac equation\nuniquely. The dynamic system S_{Dcl} has ten degrees of freedom and cannot be a\npointlike particle, because it has an internal structure. There are two ways of\ninterpretation of the dynamic system S_{Dcl}: (1) dynamical interpretation and\n(2) geometrical interpretation. In the dynamical interpretation the classical\nDirac particle S_{Dcl} is a two-particle structure (special case of a\nrelativistic rotator). It explains freely such properties of S_D as spin and\nmagnetic moment, which are strange for pointlike structure. In the geometrical\ninterpretation the world tube of S_{Dcl} is a \u0027\u0027two-dimensional broken band\u0027\u0027,\nconsisting of similar segments. These segments are parallelograms (or\ntriangles), but not the straight line segments as in the case of a\nstructureless particle. Geometrical interpretation of the classical Dirac\nparticle S_{Dcl} generates a new approach to the elementary particle theory.",
