When driving slowly around town, where drag is less of a factor, keeping Windows and sunroofs open typically USES less fuel than running the ac.
在城里低速行驶时，阻力就不是个大问题了，这样开着车窗和天窗往往会比开空调省油。
The results indicate that the head-on wind area of the TAB is the main factor in determining the drag size.
结果表明，挡流板的迎风面积是决定阻力大小的主要因素。
It also has powerful core sealing capacity, drag coefficient was greater than 32, residual resistance factor was greater than 20 and plugging rate was greater than 95%.
具有较强的岩心封堵能力，阻力系数大于32，残余阻力系数大于20，封堵率大于95%。
