Assuming that the amount of spin had not decayed too much, then the drag coefficient increased.
假设转速衰减很少，那么阻力系数增加。
It appears, however, that the "drag coefficient", CD, also depends on the velocity of the ball.
然而，阻力系数CD，也取决于球的速度。
For pure pitching motion, the results show that average drag coefficient decreases as airfoil thickness is reduced.
在低雷诺数条件下，对于纯俯仰运动，随着翼型厚度的减小，平均阻力系数也变小。
