摘要： The invention provides a multi-piece solid golf ball having a solid core, an inner cover layer and an outer cover layer, which outer cover layer has a plurality of dimples on a surface thereof. In the golf ball, the hardness relationship between the inner cover layer and the outer cover layer, the ratio of deflection between the solid core and a sphere composed of the solid core encased by the inner cover layer, and the dimple conditions are all optimized. This multi-piece solid golf ball is able to substantially reduce the distance traveled by the ball when struck at a high head speed, while at the same time holding down the decrease in distance when struck at a low head speed.

摘要： The invention provides a golf ball having a solid core, a cover of at least one layer, and a plurality of dimples on a surface of an outermost layer of the cover. The dimples number at least 250 but not more than 500, and have a volume ratio (VR) of from 1.00 to 1.40%. The ball has a deflection, when compressed under a final load of 1,275 N (130 kgf) from an initial load state of 98 N (10 kgf), of from 4.0 to 6.0 mm, and has an initial velocity, as measured using an initial velocity measuring apparatus of the same type as a USGA drum rotation-type initial velocity instrument, of from 70.0 to 76.0 m/s. This golf ball is able to substantially reduce the distance traveled by the ball when struck at a high head speed, while at the same time holding down the decrease in distance when struck at a low head speed.

摘要： The invention provides a multi-piece solid golf ball having a solid core, an inner cover layer and an outer cover layer, which outer cover layer has a plurality of dimples on a surface thereof. The value obtained by subtracting a material hardness (Shore D) of the outer cover layer from a material hardness (Shore D) of the inner cover layer is greater than −5 and less than +5. The dimples number at least 250 and not more than 500, have a surface coverage (SR) of at least 70% and a volume ratio (VR) of at least 1.0%, are of at least three types of mutually differing dimple diameter (DM) and/or dimple depth (DP), and have an average depth of at least about 0.18 mm and a diameter-to-depth ratio (DM/DP) of not more than about 23. The ball has a coefficient of lift CL at a Reynolds number of 70,000 and a spin rate of 2,000 rpm which is maintained at 60% or more of the coefficient of lift CL at a Reynolds number of 80,000 and a spin rate of 2,000. This multi-piece solid golf ball is able to substantially reduce the distance traveled by the ball when struck at a high HS, while at the same time holding down the reduction in distance when struck at a low HS.

摘要： The invention provides a two-piece solid golf ball having a core and a cover, which ball has a plurality of dimples formed on the surface. The number of dimples is from 250 to 500, the dimples have a surface coverage (SR) of at least 70% and a volume ratio (VR) of at least 1.0%, and dimples of at least three types are used. In addition, the dimples have an average depth of at least about 0.18 mm and a diameter-to-depth ratio (DM/DP) of not more than about 23. The ball has a coefficient of lift CL at a Reynolds number of 70,000 and a spin ratio of 2,000 rpm which is maintained at 60% or more of the coefficient of lift CL at a Reynolds number of 80,000 and a spin rate of 2,000. This two-piece solid golf ball lowers fluctuations in lift and drag at high and low spin rates, enabling a stable trajectory to be achieved.
摘要翻译：本发明提供一种具有芯和盖的两件式固体高尔夫球，该球具有形成在表面上的多个凹坑。凹坑的数量为250至500，凹坑具有至少70％的表面覆盖率（SR）和至少1.0％的体积比（VR），并且使用至少三种类型的凹坑。此外，凹坑具有至少约0.18mm的平均深度和不大于约23的直径与深度比（DM / DP）。球具有雷诺数为70,000的升力系数CL，并且 2000rpm的旋转比，在雷诺数为80,000，旋转速度为2000的情况下维持在升程系数CL的60％以上。这种两件式固体高尔夫球可以降低高低波动的升力和拖曳动作，实现稳定的轨迹。
