摘要： A multi-piece golf ball includes a core having a diameter of 30 to 40 mm, at least one intermediate layer including the outermost layer having a thickness of 0.5 to 2.0 mm, and a cover having a thickness of 1.0 to 3.0 mm. The core is made from a rubber composition mainly containing polybutadiene. The outermost layer is made from a non-ionomer based thermoplastic resin. The cover is made from a material obtained by dispersedly blending at least one kind of silicone powder selected from a silicone rubber powder, a silicon resin powder, and a composite powder thereof, in a main resin component containing an ionomer resin in an amount of 50% by weight or more. The core has a hardness corresponding to a deflection in a range of 3.5 to 6.5 mm under an applied load of 100 kg. The outermost layer of the at least one intermediate layer has a Dulometer D hardness in a range of 20 to 55, and the cover is harder than the outermost layer of the at least one intermediate layer and has a Dulometer D hardness in a range of 50 to 70. Dimples of the number of 300 to 550 pieces are formed in the surface of the golf ball in such a manner that a dimple total volume ratio VR, which is a ratio of the total of volumes of dimple spaces under the planes surrounded by edges of the dimples in the surface of the gold ball to the total volume of a virtual ball as a result of assumption that no dimple is formed in the surface of the golf ball, is in a range of 0.85% or less. The multi-piece golf ball is excellent in resilience, flight distance characteristic, and feel of hitting.

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)null100 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。
