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 have a volume ratio (VR) of from 1.0 to 1.4%. The ball 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 75.5 to 77.7 m/s, and a ratio of total distance traveled when struck at a head speed of 54 m/s to total distance traveled when struck at a head speed of 35 m/s (HS54/HS35) of from 1.30 to 1.50. 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 composed of a solid core encased by a cover of one or more layer, which solid core has an inner core layer and an outer core layer. The inner core layer is formed primarily of a specific, highly neutralized, ionomeric resin composition, has a diameter of from 10 to 38 mm, and has a cross-sectional hardness difference of within ±5 between any two points on a cross-section formed by cutting the inner core layer in half. The outer core layer is formed of a rubber composition made primarily of polybutadiene rubber. The solid core has a diameter of from 30 to 42 mm. The sum of the respective hardnesses at the center of the inner core layer, at the outer core layer 1 mm outside a boundary between the inner core layer and the outer core layer, at the inner core layer 1 mm inside the boundary, and at the surface of the outer core layer is set to a value in a range of from 260 to 360.

摘要： In a solid golf ball comprising an elastic solid core and a resin cover, the cover has a JIS-C hardness of 50-85, and provided that the ball receives a spin rate S1 (rpm) in the dry state and a spin rate S2 (rpm) in the wet state when hit with a short iron having a loft of an 8-iron or greater, the percent spin retention: (S2/S1)×100 is at least 47%. The ball's spin susceptibility when hit with the short iron is not reduced in the dry state or fine weather, nor is noticeably reduced even in the wet state or rain weather. The ball has so high performance that the ball travels a distance as intended, immediately stops on the green, is easy to control and thus, suited for professional and amateur low-handicap golfers.
摘要翻译：在包括弹性实心芯和树脂盖的固体高尔夫球中，该盖具有50-85的JIS-C硬度，并且规定球接收干燥状态下的旋转速率S1（rpm），旋转速度S2 当用具有8铁或更高的杆的短铁敲击时，处于湿润状态（rpm），旋转保留百分数：（S2 / S1）×100为至少47％。用短铁击球时的旋转敏感性在干燥状态或晴朗的天气下不会降低，即使在湿润状态或雨天也不会明显降低。球具有如此高的性能，使得球按预期行进一段距离，立即停在绿色上，易于控制，因此适合专业和业余的低障碍高尔夫球手。
