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。

During Eleventh Five-Year Period, the cement demand in this area will reach up to 80 million tons, this product can not only be used in building as common cement, but also can be used as jet cement, cable pipe cement and engineering cement. Therefore, it has strong market competitiveness.

国家对年产20万吨以下水泥企业实行关停转产后，本地区形成了较大的水泥市场缺口，&十一五&期间本地区水泥需求量将达到8000万吨，该产品除可作为通用水泥用于建筑以外，还可用配制喷射水泥、电缆管水泥、地下工程水泥等，具有较强的市场竞争力。
