| 摘要 |
This invention relates to a golf ball, in which a dimple distribution pattern is designed to secure the greatest possible number of axes of symmetry on the surface of a regular spherical polyhedron based on the surfaces of a regular dodecahedron, a regular icosahedron, or a dodecaicosahedron constituting a golf ball. The golf ball includes two hemispherical portions joined by a mold-parting line formed along a great circle of the golf ball. The dimples that intersect said mold-parting line are removed and replaced with equivalent dimples having aerodynamic characteristics equal to those of the dimples that are removed. The equivalent dimples are arranged in a symmetrical manner across said mold-parting line so that the golf ball may have the maximum non-directional symmetry and aerodynamic characteristics. |
