    • A golf ball has a large number of dimples on a surface thereof. The golf ball meets the following mathematical formula (I): Su ≤ 9.0 * So - 6.04 Where: So represents a ratio of a sum of spherical surface areas of all the dimples to a surface area of a phantom sphere of the golf ball; and Su represents a standard deviation (mm 2 ) of the spherical surface areas of all the dimples. Preferably, the ratio So is equal to or greater than 0.780. Preferably, the standard deviation Su is equal to or less than 2.150 mm 2 . Preferably, a number of the dimples is equal to or greater than 300 but equal to or less than 390. Preferably, an average Sa of the spherical surface areas s of all the dimples is equal to or greater than 14.00 mm 2 .
    • 高尔夫球在其表面上具有大量凹坑。 高尔夫球符合以下数学公式(I):Su‰¤9.0 * So - 6.04其中:So表示所有凹坑的球面表面积与高尔夫球体型球面的表面积之比; 并且Su表示所有凹坑的球形表面积的标准偏差(mm 2)。 优选地,比率So等于或大于0.780。 优选地,标准偏差Su等于或小于2.150mm 2。 优选地,多个凹坑等于或大于300但等于或小于390.优选地,所有凹坑的球面表面积s的平均值Sa等于或大于14.00mm 2。
