查询词典 jet boat

Jet lag jet 会使人们想到jet plane,lag是指"延迟的时间",在技术上称为"时滞"或"滞后".jet lag =jet fatigue=jet syndrome anthur j.snidir在the rhythm of life对jet syndrome的解释是:symptoms of biorhythm upset,known popularly as the jet syndrome,are experienced by jet airplane travellers who fly through several time zones in 12 hours or less.the local time between their place of departure and their destination may differ by 5,6,or even as much as 10hours.

jet lag是随着喷气式飞机的问世，乘喷气式客机旅行的人越来越多的情况而出现的。jet lag不是什么喷气时滞，而是人们在乘坐喷气式飞机旅行时由于时差的关系而引起不适应目的地昼夜变化的一种疲劳和烦躁的现象。

It can be concluded that, when the jet is injected at positive angles, the initial section of the jet increases and the region affected by the jet decreases in the vertical direction; moreover, the circumfluence toward the jet exit becomes more obvious, and the separation events in the lee of the jet weaken. When the jet is injected at negative injection angles, it disarranges the flow upstream and the curvature of jet trajectories varies smartly along the flow direction.

结果表明：射流正向倾斜入射时，射流起始段增加，在垂直方向对主流场的影响区域减小，射流喷口上游位置处的&孔吸流动&更为明显，射流出口下游背风侧的分离现象逐渐减弱；射流反向倾斜入射，对上游流场的扰动增加，射流在弯曲段内曲率变化大。

In the multiple turbulent jet-to-crossflow, the"hole inhale phenomenon"is more obvious in the lee of the first jet orifice. We got the vortex fields of the multiple turbulent jet-to-crossflow in different conditions. The developing processes of horseshoe vortex and kidney counter-rotating vortex pair are studied. The results suggest that in the multi-hole jet, until the multi-hole jet merging into a new jet, the miniature of horseshoe vortex appears, and the shape of CVP changes regularly.

计算还给出了不同工况多孔横向紊动射流的涡量场，并对马蹄形涡和反向涡旋对的形成机理及发展过程进行了系统的研究，并指出，在多孔射流中，当多股射流合并为一股新的射流之后，才出现马蹄形涡的雏形，CVP的形状也逐渐变的规则。

Spectrometer was adopted to measure the emission spectrum of argon plasma jet at the ignitor exit; boltzmann curve slope method was applied to caculate the jet electron temperature; ionization equilibrium equation was used to caculate jet temperature and measured a law that length, electron temperature and jet temperature of ignitor exit jet length changed with arc current and flowrate.

采用光谱仪测量了氩气等离子体射流在点火器出口的发射光谱，利用玻尔兹曼曲线斜率法计算了射流的电子温度，并通过电离平衡方程计算了射流气体温度，测得了点火器出口射流的长度、电子温度和射流温度随弧电流以及流量的变化规律。

The shear layer vortices dominate in the initial portion of the jet, which are a result of the K-H instability. The crossflow encounters an adverse pressure gradient ahead of the jet and separates to form horseshoe vortices under the pressure downstream, and they develop into the wake. The wake vorticity comes into being in the actions of an adverse pressure gradient and a wall-normal component of vorticity, which originates from the wall boundary and is entrained into the jet. The shear layer vortices encounter adverse pressure gradients in the lee of the jet and break down, leading to the formation of the CVP and the CVP is the most important characteristic of the jet in crossflow.

文中指出：剪切层涡源于射流与横流之间的K-H不稳定性；马蹄形涡的产生是由于射流喷口上游迎风侧的壁面边界层内存在逆压梯度，使流动发生了分离，在下游逆压梯度的挤压作用下，形成了马蹄形涡，马蹄形涡向下游发展，进入尾迹区；在逆压梯度和法向涡生成项的共同作用下产生了尾迹涡，尾迹涡源于壁面边界层，止于射流，并将部分涡量向上输运至射流内部的CVP；CVP是横向紊动射流的重要特征，剪切层涡破裂后，在逆压梯度的作用下CVP形成。

And E.N.E: Had they seen the Island, as I must necessarily suppose they did not, they must, as I thought, have endeavour'd to have sav'd themselves on Shore by the Help of their Boat; but their firing of Guns for Help, especially when they saw, as I imagin'd, my Fire, fill'd me with many Thoughts: First, I imagin'd that upon seeing my Light, they might have put themselves into their Boat, and have endeavour'd to make the Shore; but that the Sea going very high, they might have been cast away; other Times I imagin'd, that they might have lost their Boat before, as might be the Case many Ways; as particularly by the Breaking of the Sea upon their Ship, which many Times obliges Men to stave, or take in Pieces their Boat; and sometimes to throw it over-board with their own Hands: Other Times I imagin'd, they had some other Ship, or Ships in Company, who upon the Signals of Distress they had made, had taken them up, and carry'd them off: Other whiles I fancy'd, they were all gone off to Sea in their Boat, and being hurry'd away by the Current that I had been formerly in, were carry'd out into the great Ocean, where there was nothing but Misery and Perishing; and that perhaps they might by this Time think of starving, and of being in a Condition to eat one another.

如果他们发现这个小岛，我想他们一定会用船上的救生艇竭尽全力划到岸上来的。但看来他们一定没有看到小岛，只是鸣枪求救，尤其是他们看到我燃起的火光后，更是多次放枪。由此我头脑里出现了种种设想。首先，我想到，他们看到我点燃的火光后，必然会下到救生艇里拼命向岸上划来，但由于风急浪高，把他们刮走了。一会儿我又猜想，也许他们的救生艇早就没了，这种情况是经常发生的。当大船遇到惊涛骇浪时，水手们往往不得不把船上的救生艇拆散，甚至干脆扔到海里去。过会儿我又想，也许与他们结伴同行的船只，在见到他们出事的信号后，已把他们救起来带走了。我又想到，说不定他们已经坐上救生艇，可是遇到了我上次自己碰上的那股急流，给冲到大洋里去了。到了大洋里，他们可就糟了，那是必死无疑的。说不定这会儿他们都快饿死了，甚至可能正在人吃人呢！

As soon as they got to the Place where their other Boat lay, they run their Boat in to the Beach, and came all on Shore, haling the Boat up after them, which I was glad to see; for I was afraid they would rather have left the Boat at an Anchor, some Distance from the Shore, with some Hands in her, to guard her; and so we should not be able to seize the Boat.

那批人来到头一只小船停泊的地方，马上把他们自己的小船推到沙滩上，船上的人也通通下了船，一起把小船拉到岸上。看到这一情况，我心里非常高兴。因为我就怕他们把小船在离岸较远的地方下锚，再留几个人在船上看守。那样我们就没法夺取小船了。

As soon as they got to the Place where their other Boat lay, they run their Boat in to the Beach, and came all on Shore, haling the Boat up after them, which I was glad to see; for I was afraid they would rather have left the Boat at an Anchor, some Distance from the Shore, with some Hands in her, to guard her; and so we should not be able to seize the Boat.

他们把这两个人都绑了起来安置在洞里，但照样供给他们吃喝，并答应他们，如果他们安安静静地呆在洞里，一两天之后就恢复他们的自由；但如果他们企图逃跑，就格杀勿论。
