冲刷

NOTE : Open the drain valve at least once every month or more often during boiler operation to flush out sediment from the float chamber.

注：每个月至少打开排水阀一次，在锅炉使用期间甚至可以更多次，从浮子腔内冲刷出沉淀物。

The reaction characteristics of flocculus formed in the reaction of cationic polymer to hydrolyzed polyacrylamide and the mass ratio of cationic polymer to HPAM in complete reaction were investigated experimentally. The flocculus has good ability to reduce the core permeability and the capability of washout resistance.

室内实验结果表明，阳离子聚合物与阴离子聚合物发生反应可产生稳定的絮状沉淀，完全反应时阳、阴离子聚合物的质量比为 30∶1；当絮状沉淀的浓度较高时，它具有很好的携砂能力，絮状沉淀可使岩心的渗透率降低 88%以上，且具有良好的抗冲刷能力。

On the basis of previous study on deep channel, the South Branch,Xinqiao Channel,Nanxiaohong and Main Channel of Nangarg are chosen as the typical flood and ebb channels. Field data sampled in the flood season of 2001 and the dry season of 2003 are used as the base of the analysis of hydrodynamic characteristics, such as current, sediment, dominant current and dominant sediment.

在前人对河口冲刷槽研究的基础上，选择长江口南支、新桥水道、南小泓和南港主槽作为典型涨、落潮槽研究对象，以2001年洪季和2003年枯季实测资料为根据，比较分析了长江口涨落潮槽的水流、泥沙、优势流和优势沙等动力特征，结果表明用单一因子分析河槽性质不够全面。

Under the plain irrigation area dam floodgate washes out the destruction to be serious also the universal existence.

摘要* 平原灌区水闸闸下冲刷破坏严重且普遍存在。

In this, the eleventh release from world renowned flutist Nicholas Gunn, to "Breathe" is also the essence of life that is often overlooked by everyday routine. Other tracks delve into Spanish flamenco flavors ("Rosarita Sunset") and rainforest idylls ("Sacred Journey"). Evocative landscapes of sound blend the peace of a Zen meditation with the untamed beauty of the Andes in "La Morada in El Tempo Antiguo."

无论是耀眼的阳光下，他仿佛为一杯清凉而爽口的冰镇乌梅汁，可以舒服的更加感受阳光心情的快乐；也可以在乌云密布的悲哀失望时，更似一味心灵鸡汤，给你振奋，给你鼓励，不断的冲刷中，过滤掉许多的烦恼和忧愁，仿似站立在悬崖峭壁，神臂展望四周般的心血澎湃。

Therefore study on riverbank erosion mechanisms and their application, can not only enrich and develop the basic theory of fluvial process, but also perfect and advance the current sediment mathematical models.

因此河岸冲刷机理及其应用研究，不仅能丰富和发展河床演变学的基本理论，而且能进一步完善和提高现有的泥沙数学模型。本文的主要研究内容如下

In Yosemite Creek, frazil ice has frequently covered trails and damaged bridges, and has even flowed through buildings that once bordered the creek. In 1997, frazil ice was above the railings of the Lower Yosemite Fall Bridge, almost completely burying it!

在约塞米蒂溪谷中，"水内冰"常常会盖满小路并对桥梁造成损伤，甚至还冲刷过以前曾建在溪边的建筑。1997年，"水内冰"盖过了约塞米蒂瀑布底部桥梁的扶手，几乎将其全部淹没！

Because the metal melt fluid washes outthe furnace lining unceasingly as the metallurgy smelting, the different furnace lining material, the furnace lining smelting life is dissimilar, so power frequency furnace is also same as any other type smelting when they are manufactured, not equiping with furnace lining material, the using factoryshould have the professional furnace lining technical personnel and furnaceman.

由于冶金熔炼时，金属熔液不断冲刷炉衬，不同的炉衬材料，炉衬熔炼寿命也不一样，不同的金属所适应的炉衬材料也不一样，所以工频炉出厂也同任何种类熔炼出厂一样，不配备炉衬材料，使用厂应备有专职的炉衬技术人员和筑炉工。

Because time metallurgy smelting, the metal melt fluid washes out the furnace lining unceasingly, the different furnace lining material, the furnace lining smelting life is dissimilar, the different metal adapts the furnace lining material is dissimilar, therefore power frequency stove leaving the plant is also same as any type smelting leaving the plant, does not provide the furnace lining material, the use factory should have the professional furnace lining technical personnel and build the furnaceman.

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
