The results show us that, the deflection of the air flow direction has the linear relationship with the baffle installation angle;
结果表明，加装挡板后气流方向的偏转与挡板安装角度有一定线性关系；
The Model AS-2 is designed to check velocity and direction of air flow continuously with a smoke tube (No. 301) which reacts with vapour in the air and generates white smoke.
该型号AS - 2的目的是检查速度和方向的空气流动的烟管（301）的反应与空气中的蒸汽并产生白烟不断。
The air flow rate around stripped rotor was analyzed and studied. The velocity decreased with the increasing of the radius and the direction was perpendicular with the direction of radius.
