与身体分隔的紊乱的空气产生涡流进而造成空气阻力，使得车速下降。

Disrupted air, where the flow 'separates' from the body, creates turbulence which creates drag - which slows the car down.

阻力模拟则是控制电涡流测功机，使其转速与制动力矩间的关系符合相应状况下的车速、阻力关系。

Resistance simulation control electricity eddy current system, make the revolving speed and braking moment relation accord with the condition of correspond speed and resistance relation.

结果表明：斜截半柱面涡流发生器是一种强化换热效果好又阻力损失小的涡流发生器型式。

It is suggested that the oblique-cut semi-cylinder shell is a kind of VGs with efficient heat transfer enhancement but low pressure drop.
