这句话的意思是：正如线性动量是质量和速度的乘积一样，一个物体的角动量定义为惯性矩和它的角速度的乘积。

Because the body inertia in ball hitting moment was very small, the angular momentum was mainly affected by angular velocity. In the phase, the average value, largest value and hitting moment value of angular momentum with kick hitting are larger than those with glide hitting. Therefore, the kick hitting could get larger linear and angular momentum.
