Hence, to reduce the effect of the air cone on the classifying of the hydrocyclone, parameters of suitable cone angles and related optimal in-let flows should be selected for the hydrocyclone.

因此，为减少空气柱对旋流器分离效率的影响，旋流器应采用合适的锥角及与之相匹配的最佳进口流量。

The shock wave forms a cone of pressurized air molecules which move outward and rearward in all directions and extend to the ground.

冲击波形成了一个由压缩气体分子构成的圆锥体，它朝四面八方向外和向后移动，一直延伸到地面。

Airplanes flying faster than sound create a cone of pressurized air molecules that extends to the ground, as NASA explains.

据NASA解释，飞机在超音速飞行时会产生延伸到地面的加压空气分子锥。

About half the rockets suffer some kind of catastrophic failure in the air, usually when a nose cone fails to separate properly or the parachute doesn't deploy.

FORBES: "Let's Punch A Hole In the Sky"

That's partly the fault of the government, which prohibits amateurs from using explosives powerful enough to blast the nose cone free when the rocket is whistling through the air at supersonic speeds.
