    摘要： A golf ball including an inner core having a first outer surface and a geometric center and being formed from a first substantially homogenous composition such that the inner core has a hardness of about 60 Shore C to about 90 Shore C; an outer core layer disposed about the inner core having a second outer surface and being formed from a second substantially homogenous composition such that the outer core layer has a hardness of about 60 Shore C to about 95 Shore C; and a cover layer disposed about the outer core layer. The geometric center and first and second outer surfaces each have a hardness, the hardness of the second outer surface being lower than the hardness of the geometric center to define a negative hardness gradient.

    摘要： A golf ball includes an inner core having a first outer surface and a geometric center and is formed from a first substantially homogenous formulation throughout such that the inner core has a hardness of 30 Shore C to 45 Shore C. An outer core layer is formed around the inner core and has a second outer surface and an inner surface and is formed from a second substantially homogenous formulation throughout such that the outer core layer has a hardness of 60 Shore C to 95 Shore C. A cover layer is formed around the outer core layer. The hardness of the first outer surface is lower than the hardness of the geometric center to define a negative hardness gradient, and the hardness of the second outer surface is greater than the hardness of the inner surface to define a positive hardness gradient.
