Hangzhou red wheat Craft skin sign Factory Is situated atsouth the Yangtze River delta wing ,Hangzhou bay west end ,Qiantang River downstream,Jing Hang big canal south tip of,Is Yangtze River delta important key city With China southeast transportation key position .

杭州红麦工艺皮标厂地处长江三角洲南翼，杭州湾西端，钱塘江下游，京杭大运河南端，是长江三角洲重要中心城市和中国东南部交通枢纽。

In the experiment focused on decadal changes, GCMs reproduce the observed NAO shifts in recent decades by imposing strengthening trends on stratospheric wind. The cooling belt extending from North Africa to subtropical Eurasia is simulated accompanying the strengthening of NAO. East end of this cooling belt reaches the eastern flank of Tibetan Plateau.

在强调年代际变化的实验中，通过在平流层中强迫出水平风场的线性增强趋势，大气环流模式可以模拟出近几十年间冬季NAO指数的年代际上升；伴随着NAO正位相的增强，模式可以再现北非至副热带欧亚大陆的冷却带，且其东端可以到达青藏高原下游地区。

Change the propulsion of the process as town, while original production and life pollution have not effect a radical cure, a few new contaminant arose again, expand of dimensions ceaselessly as town especially, mushroom of population of industry and agriculture, the generation of a large number of liquid waste and pallet catchment means pollute downstream water area directly.

随着城镇化进程的推进，在原有生产和生活污染尚未根治的同时，一些新的污染物又产生了，特别是随着城镇规模的不断扩大，工农业人口迅速增加，大量废水的产生和简陋的排水方式直接污染到下游水域。

The experimental results show that the current in the wake downstream the impeller is obviously 3 dimensional.

实验结果表明：风轮下游尾迹区内气流存在明显的三维性。

Corresponding to simulation results, middle flow shows more regular because vortex separation from upstream tube bundles suppress the vortex generation in downstream.

由于多个拟序的涡结构在下游不断的相互作用使得尾迹中的涡结构越来越混乱。

Back pressure :The pressure exerted on the downstream side of a valve seat.

背压力：作用于阀门下游侧的压力。

If a valve downstream from the filter is shut too fast, the water pressure will reverse and can cause "ballooning".

如果过滤器的下游水阀门关闭太快，水压会倒转，而形成气泡。

In this paper,mathematical expressions of some swirl characteristic s of typical level hollow swirling flow in inner dissipation discharge tunnel with inlet shaft have been put forward under velocity distribution supposition.

试验观测结果表明，相对于起始断面的各种旋流特性具有明显的分段性质和沿程衰减的特性；下游水位对空腔环流的旋流特性有显著的影响。

Having analyzed the sliding of gravity dam foundation with a weak intercalation for failure process and destabilization mechanism by the non-linear finite technique ,it proved to be true that the second sliding surface in tail rock resistance block would be inclined to the downstream side but not simply vertical.

通过非线性有限元分析了具有软弱夹层的重力坝坝基滑动破坏过程和失稳机理，论证了尾岩抗力体第二滑裂面应向下游倾斜，而不宜简单地取为直立。

Shrinking lakes and rivers, the Yellow River drying up in the Yellow River from 1972 to the beginning of 1998 there disconnection of the 27 years, the Yellow River Lijin station stop in a total of 21, reached four years of stop-off frequency, for a total disconnection 1,050 days, the average Each year 50 days disconnection, 1997 devascularization 226 days, up to 704 km river drying up of the lower reaches of the chief of 90%.

河湖萎缩，黄河断流黄河从1972年开始出现断流到1998年的27年间，黄河利津站共有21年发生断流，断流频率已达四年五断，共计断流1050天，平均每个断流年份50天，其中1997年断流226天，断流河段长达704公里，占下游河段总长的90%。
