Dimpled golf ball

摘要

When the spherical surface of a golf ball is divided into a plurality of substantially congruent spherical triangles, dimples are substantially equally distributed in the spherical triangles. The spherical triangles are minimum triangular units which are substantially congruent with each other. The dimples distributed in each minimum triangular unit include crossing dimples that each lie across a side of the minimum triangular unit. The total of the crossing lengths of the crossing dimples is 70-80% of the total side length of the minimum triangular unit. The golf ball is improved in the symmetry of elevation angle and carry, and has good aerodynamic performance and an increased total flight distance.
