GOLF BALL

摘要

A golf ball which comprises a spherical surface having a parting line at its equator and having a plurality of dimples formed thereon, wherein the dimples are formed so that the ratio, y, of the sum total of the flat surface area of the dimples to the surface area of the same sphere having no dimples formed thereon is within the range ((0.046) (X)1/2-0.172)+0.04>/=Y>/=((0.046)(X)1/2-0.172)-0.04 wherein X represents the total number of dimples; and wherein a dimple lying within a region S, which extends from 30 DEG below the parting line to 30 DEG above the parting line, has a value VS, and a dimple of the same diameter only lying within the region P, which comprises the surface of the sphere that is not within region S, has a volume VP, such that the ratio of the volumes of dimples having the same diameters but in different regions is within the range of; 1.02
