Description
さらに、この実施例は、(規定された場所での)垂直参照軸に沿った第1の材料の割合が重要であるという結論につながった。例えば、分離した空隙(錠剤形状)レビジョン4Aのパターと分離した空隙(円形状)のパターを比較したとき、第1および第2の材料の硬度は、実質的に同じであったが、打撃面に沿った第1の材料の割合は変わった。中心から外れたインパクト時に、分離した空隙(錠剤形状)レビジョン4のパターは、打撃面中心で生成されるボール速度よりもわずか0.4%変わった。分離した空隙(円形状)は、打撃面中心で生成されるボール速度と比較したとき、中心から外れた打撃時に約0.8%変わった。したがって、打撃面全体で生成されるボール速度を制御するとき、垂直参照軸に沿った第1の材料の割合は、均一なヒール・トウのヒット面を生成するのに役立つ別の重要な変数である。

Furthermore, this example led to the conclusion that the proportion of the first material along the vertical reference axis (at the defined location) is important. For example, when comparing a separate void (tablet shape) Rev. 4A putter to a separate void (circle shape) putter, the hardness of the first and second materials were substantially the same, but the striking surface The proportion of the first material along has changed. On off-center impact, the discrete void (tablet shape) Rev. 4 putter changed only 0.4% from the ball velocity generated at the center of the striking face. The separate air gap (circular shape) changed about 0.8% on off-center hits when compared to ball velocities generated at the center of the hitting face. Therefore, when controlling the ball velocity produced across the striking face, the proportion of the first material along the vertical reference axis is another important variable that helps produce a uniform heel-toe hitting face. be.
