流线型流动

The geometry of the air spaces and fixed resonance chambers is "streamlined"; there is only one set of functional vocal cords; the vocal cords are mounted in the air tunnel in such a way that, when adducted, they can produce sound only on expiration, instead of allowing both inspiratory and expiratory voice; and the epiglottis has moved so far below the pharynx as to allow the air from the larynx to stream freely through both nasal and oral cavities.

空气空间的几合学及固定共鸣室是流线型的；只有一组实用的声带；声带以这样的方式（当合陇时，他们只能在吐气时产生声音，而不是允许吸气及吐气声音）镶嵌在空气的通道上；且会厌到现在已移到咽头下方让从喉头来的空气自由地流动通过鼻腔及口腔。

According to the velocity filed mentioned above, the contour of the drawing die was rationally designed. To prove its applicability and superiority, FEM software, MARC and SUPERFORM, were used to simulate the drawing process of cross tube in "conical die" and "streamlined die".

本文以十字形钢管为研究对象，开展对异型钢管拉拔成形过程研究，首先结合挤压流线理论，设计了&流线型&拉拔速度场模型，这为改善金属流动状态、降低能耗创造了良好条件；紧接着以&流线型&速度场为理论依据，对十字形管拉拔模具的凹模轮廓进行了合理设计。

A separation in the boundary layer of fluid about a moving streamlined body, such as the wing of an airplane, causing a breakdown in the smooth flow of fluid and resulting in turbulence.

例句1。气流分离移动的流线型的躯体上流体边界层上的分隔物，如飞机的机翼，在平滑的流体流动中会引起故障和湍流
