流线型liúxiànxíng前圆后尖,表面光滑,略像水滴的形状。具有这种形状的物体在流体中运动时所受阻力最小,所以汽车、火车、飞机机身、潜水艇等的外形常做成流线型。{streamline; line of flow; shape that resembles a drop of water, being round at the front and pointed at the back, with a smooth surface. Objects of this shape meet with the least resistance when moving through fluid, so cars, trains, plane fuselages, submarines, etc., are generally streamlined.} |
