查询词典 jet-black

A daredevil wearing a jet pack flew across a 1,500-foot-wide canyon in Colorado in November. A Swiss pilot, dubbed "Fusion Man," flew across the English Channel last year using a single jet-propelled wing.

去年11月份，身着个人飞行器的一位冒险者穿越了位于科罗拉多州的一个宽1500英尺的大峡谷；去年，称为&聚变人&的一位瑞士飞行员用喷气引擎整体机翼飞过了英吉利海峡。

Switzerland —Neither a bird nor a plane,"Jet Man"—aka adventurer Yves Rossy—soars above the Alps on jet-propelled wings during a five-minute, 186-mile-an-hour flight.

瑞士—-那不是一个鸟，，也不是飞机，&喷气人&，有名冒险家伊夫 Rossy ，飞机在阿尔卑斯山上方腾飞推进5分钟，时速每一小时186英里的飞行翼。

Thus ensuring axial symmetry of the nozzle and jet pipe in the structure design is the key of preventing the jet pipe from being pressed and locked.

保证喷嘴、喷管结构的轴对称性是防止喷管后段成为受压缩状态、乃至导致摩擦锁止的关键。

In this thesis an analysis is made for differences in jet structure, wavenumber, frequency and growth rate of disturbance surface wave of a liquid jet under conditions when temporal and spatial modes are respectively applied.

利用对色散方程的求解结果，本文详细地比较了液体射流研究中的时间模式和空间模式在各个方面的关系和差异，以及这种差异的影响因素。

In operation, the downhole devices will be laid down with tubings which will move up and down using the operation machine. Since the injection head can rotate in the determined speed, the rotating flow, compared with the conventional stable axial flow, can prevent the sands from depositing in the horizontal annular and washing the screen. The jet from high-efficiency jet nozzle will wash the screen directly with concentrated hydro-power. The working fluid can be clean water, without damage to the formation.

作业时用油管下入该井下装置，利用作业机带动油管上下移动，由于喷头可按照既定速度旋转，返回流体在水平段由常规的平稳轴向流动变为旋转流动，既可实现对防砂管的全方位解堵，又能避免砂粒沉积；高效喷嘴产生的射流直接对着防砂管冲击，能量集中；工作介质为清水，不会对地层带来二次污染。
