    • Generally disclosed is a golf ball having a core and a cover layer. The cover layer includes areas that are hard corresponding to the dimples, and areas that are soft corresponding to the land between the dimples. The cover layer may be selectively treated, such as by heating, to achieve a difference in hardness using a single cover layer material. Alternatively, the cover layer may be selectively coated with a coating material having a different hardness. As a result of the arrangement of the hard dimples and the soft land, the golf ball achieves reduced spin, and greater distances, when struck with a larger force (such as during a drive) while also achieving increased spin, and better control, when struck with a smaller force (such as during a chip).
    • 通常公开的是具有芯和覆盖层的高尔夫球。 覆盖层包括对应于凹坑的硬区域,以及对应于凹坑之间的焊盘的软区域。 可以例如通过加热来选择性地处理覆盖层,以使用单个覆盖层材料来实现硬度差异。 或者,覆盖层可以选择性地涂覆具有不同硬度的涂层材料。 由于硬凹坑和软土地的布置,高尔夫球实现减少的旋转和更大的距离,当受到较大的力(例如在驱动期间)时,同时也实现增加的旋转和更好的控制,当 受到较小的力(例如在芯片期间)。
