| 球回弹性的问题： The problem of ball resilience: 球回弹性的试验是将篮球从6.6英尺的高度落到运动地板上，测试篮球的回弹高度。这个数据以百分比表示，以篮球在水泥地上回弹的高度为对比标准，反映回弹高度差。室内球类运动比赛规则要求，借助地面进行体育比赛或训练，如篮球等球类的运动的起跳动作和球体的反弹，要求球体在比赛场地地面上的反弹比较系数应大于或等于90%。较专业的塑胶运动地板拥有杰出和稳定的球回弹性能，地板上不存在任何弹性死点，它的反弹比较系数最高能达到98%。 The test of ball resilience is to drop the basketball from 6.6 feet to the sports floor to test the rebound height of basketball. This data is expressed in percentage, and the rebound height of basketball on the cement ground is taken as the contrast standard, reflecting the rebound height difference. According to the rules of indoor ball games, it is required to conduct sports competition or training with the aid of the ground, such as the take-off action of ball games such as basketball and the rebound of the ball, and the rebound comparison coefficient of the ball on the ground should be greater than or equal to 90%. The more professional plastic sports floor has outstanding and stable ball rebound performance, there is no elastic dead point on the floor, and its rebound comparison coefficient can reach 98%. |
