The air being dragged across the top of the spinning ball moves in the same direction as the air that's rushing past.
球所带起的这层空气旋转到球上方时,它的运动方向与周围气流的方向一致&XbxnF-)Fs
As the air spinning with the ball comes around the bottom it is moving in the opposite direction from the air on top, and therefore against the onrushing air.
当这层空气到球底部的时候,其运动方向与上方空气相反,因此与周围气流相抵tGn8nG^f=D85S8tLmiF|
Consequently it's slower than the air on top.
这样会导致下方的空气速度较上方更缓慢rg#c;kNxW84

A slow moving air stream has higher pressure than a fast moving air stream.
缓慢流动的气流比快速流动的气流压强大]X%Zf,hxNXy4|R
So, the higher pressure on the bottom of the ball is going to hold the ball up longer.
因此,球底部较高的气压可以把球向上托,促使其在空中停留更长时间#fi(1&RNd[nvInoi,
The effect of the dimples is so significant that a drive of two-hundred yards hit with a dimpled golf ball,
这些凹痕的作用十分重要,同样的一杆,如果可以把有凹痕的高尔夫球击出200码,
would be shortened with a non-dimpled ball to about one hundred yards.
那么相同条件下,只能把没有凹痕的球击出约100码c]b4VkO0sAGp8lF
