查询词典 piercing jet

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。

For most piercing-sucking insects, they will secrete gell saliva and watery saliva when they feed on plants. The gell saliva will be secreted at the early stage of feeding to form salivary sheath, which is supposed to surround and protect the stylet. This saliva can help piercing-sucking insects to feed on plants directly and indirectly. Meanwhile, the watery saliva contains many components like pectnase, cellulose, polyphenol oxidase, peroxidase, alkaline phosphatase, sucrase, etc. These components can help piercing-sucking insects in plant tissue penetration, food digestion, detoxification of plant secondary substances and break-down of plant defence reaction.

对多数刺吸式昆虫而言，他们取食时会分泌胶状和水状两种唾液，其中胶状唾液会在取食早期分泌形成唾液鞘来围绕并保护口针，通过直接和间接的作用来帮助取食；而水状唾液中则包含了果胶酶、纤维素酶、多酚氧化酶、过氧化物酶、碱性磷酸酯酶、蔗糖酶等组分，来帮助刺吸式昆虫对植物穿刺、消化食物、解毒次生物质并破坏植物的防御反应。

Body piercing literally means to have a part of your body pierced, in order to wear jewellery in the hole made.Ear piercing is the most common form of body piercing.

身体穿孔的字面意思有一部分你的身体穿孔，在以磨损，珠宝首饰，在孔made.ear穿孔是最常见的形式，身体穿孔。

彩喷纸的表面性能是影响喷墨打印效果的重要因素之一，特别对彩喷纸的解像力有很大的影响，而对于涂布的彩喷纸来说，胶粘剂的性质直接影响纸张的表面性能。

Reynolds number of impingement, inclined jet angle, the ratio of the jet distance to the diameter of the jet hole and the relative curvature (the ratio of the diameter of jet hole to the diameter of concave surface) were changed to study the rules of flow structures varying with these parameters. At the same time, the developing and disappearing phenomena of the induced vortex were analyzed.
