水流

It is demonstrated that the vehicle can achieve station keeping under the closed loop control of the two proposed methods in the presence of man-made abrupt disturbances and current disturbances.

演示实验表明：在两种视觉悬停方法的闭环控制下，水下机器人能够抵抗恒定水流干扰和人工位置扰动，很好地实现水下悬停作业。

The tidal current, suspended sediment concentration and bed load grain size at Humen estuary of the Pearl River in spring tide during flood season in 2004 were observed by using ADP and traditional survey instruments.

2004年洪季大、中潮期间，用声学多普勒流速剖面仪和传统观测方法对珠江口虎门水域水流、悬沙浓度及底质粒度进行了现场多点同步观测。

Moreover, with the assistance of grey series forecasting model and the rule of the annual precipitation, the annual average precipitation, groundwater flow field, groundwater level and spring flow in the future under current exploitation circumstances were forecasted. If 2010 is a high flow year (guarantee ratio 20%), or median flow year (guarantee ratio 50%), or even low flow year (guarantee ratio 75%), the underground water level of Heilongdong spring in flood season will exceed 130 m, or reach 130 m, or even below 130 m, and the spring flow in flood season will exceed 10 m^3/s, 7 m^3/s, 5 m^3/s respectively.

以灰色序列预测模型为辅助手段，结合历年的降水规律，对未来现状开采条件下的年均降水量、地下水流场、水位及泉流量进行了不同保证率条件下的预测，若2010年为丰水年（保证率20%）、平水年（保证率50%）、枯水年（保证率75%，黑龙洞泉汛期地下水位标高分别为超过130m、达到130m、低于130m，汛期泉流量分别为超过10立方公尺/s、7立方公尺/s、5立方公尺/s。

Trees and brush powdered with fresh snow flank the icy stream's sides.

树木和画笔粉状的和初雪面临着冰冷的水流的一侧。

As he spoke there was a plash in the water; I caught the arrowy gleam of a scared fish shooting into the middle of the stream, my hook hung empty from the line.

在他说话的时候，我听到水中响起了&啪&的一声；我看到一道笔直的银光直接射进了水流的中央，鱼钩空空地吊在鱼线上。

The relation ship of net positive suction head of pump versus silt-content in silt- leder water flow is analyzed and established theoretically.

从理论上分析推导了抽送含沙水流时泵的汽蚀余量随含沙量的变化关系。

At the maximum head, the shaft power of prototype pump is less than 2 300 kW. The hydraulic model and optimal straight outlet conduit meet the operating condition of the pumping station.

所选用的水力模型性能满足泵站的实际运行要求，经过优化的直管式出水流道保证了泵装置高效稳定运行。

Mom Mangba sewer pipe leading to twist open, then a small loach down the water flow out!

妈妈忙把通向下水道的弯管拧开，这时小泥鳅顺着水流流了出来！

We can relate to the intense self-restriction Luo Quanmu imposes on his painting, a kind of self-satisfied, inherent trait. It is like a pum, which having sucked a spring dry, moves on to the waters of its own imagination, pouring these atop the canvas.

我们可以体验到他绘画的那种强烈的自我限定，一种自足的、内在循环的特性，这就像一座水泵抽空了现实的水源，而将自身想象力的水流缓慢地灌注到绘画空间之中。

Just as I had set my Mast and Sail, and the Boat began to stretch away, I saw even by the Clearness of the Water, some Alteration of the Current was near; for where the Current was so strong, the Water was foul; but perceiving the Water clear, I found the Current abate, and presently I found to the East, at about half a Mile, a Breach of the Sea upon some Rocks; these Rocks I found caus'd the Current to part again, and as the main Stress of it ran away more Southerly, leaving the Rocks to the North-East; so the other return'd by the Repulse of the Rocks, and made a strong Eddy, which run back again to the North-West, with a very sharp Stream.

我刚竖起桅杆张好帜，船就开始向前行驶了。我发现四周水色较清，知道那股急流在附近改变了方向。因为，水急水则浊，水缓水则清，我知道那股急流在这儿已成了强弩之末了。不久我果然发现，在半海里以外，海水打在一些礁石上，浪花四溅。那些礁石把这股急流分成两股，主要的一股继续流向南方，另一股被礁石挡回，形成一股强烈的回流，向西北流回来，水流湍急。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
