冲刷

This low carbonate event may have resulted from changes of rainfall. During deglaciation, the dry climate caused a decrease in terrigenous sediment input. However, during Early-Middle Holocene, the rainfall, especially the heavy rain with higher erosions increased rapidly, leading to the increase of terrigenous sedimental supplies from South China mainland and Hainan islands.

在冰消期，出现干旱，陆源物质减少，而早中全新世的雨量，尤其是具较强冲刷能力的大雨量急剧增加，造成北部海南岛和华南陆地的冲刷增强，陆源物质供给增加，从而出现低钙事件。

Then, three kinds of approaches to simulating the bank erosion process are systematically discussed, which are empirical, extremal hypothesis and mechanical approaches.

首先分析了受冲积作用控制和不受冲积作用控制的河岸冲刷机理，阐明了河岸冲刷过程中的力学关系及主要影响因素。

搁置不任冲刷或不任化学办理版材令出产效果更矮这栽低速制版是随着不任冲刷或不任化学办理版材呈现而风行不躺下的。

Float chamber should be flushed at least once every month or more often to remove any accumulated sediment by opening drain valve where installed or removing drain plug.

浮子腔至少每个月冲刷一次或更多次以清除任何累积的沉淀物。如果有安装排水阀，则打开排水阀；如果没有安装排水阀，则拆卸排水塞，来实现浮子腔的冲刷。

The equivalent gradient of the back-slope of the eroded pit near the head of the groyne is less than a critical value of JD,which is related with the rest angle of the scoured out silt under water.

分别考虑了水道流速、土颗粒等效直径、冲刷坑半径、冲刷坑后坡度临界值和水流方向角为相关或独立的非高斯随机参数时的可靠性问题。

Changes of erosion and accumulation of the seabed before and after the project The general characteristics of the pattern of erosion and accumulation of the seabed near the scheduled project both before and after the scheduled project are as the following: accumulation occurs at the areas lower than–10 isobath; some suspended sediment is deposited near the coast due to the relatively small tidal current with a monthly accumulation rate of 2-6 mm; while a slight erosion occurs in the areas deeper than–10 isobath with a monthly accumulation rate of .2 mm.

5工程前后海底冲淤变化工程前后海底冲淤相同的地方是：大致沿-10m等深线向近岸呈淤积状态，近岸由于潮流流速小，一些悬沙落淤，月淤积量在近岸附近约2-6mm；而-10m等深线以深基本上呈轻微冲刷状态，月冲刷量一般在0.2mm以下。

Impact strength and wear resistance are increased because graphite has the effect of plasticization and anti f...

但是，冲刷磨损时易形成犁削和形变蚀坑，导致冲刷磨损性能下降。

Agfa's company has also modified its cleaning system, the new scourability version of the machine, the resulting liquid waste be reduced by over 40 per cent, under normal circumstances flushing per square metre plates produce not exceeding 300 ml of liquid waste (including developering, Replenisher developer、Fixer agents and the volume of water added together), in addition to the waste water treatment become more easily, saving water and chemical usage in order to achieve the objective of environmental protection.

爱克发公司也保守了它的冲刷编制，陈的冲版机所爆发的废液量增多了40%，在侧常境况下冲刷每平方米印版爆发不不及300毫升的废液（包含显影液、补偿液、定影剂及火增不躺下的量），除了令废液的办理处事变得更沉重边，同时耗费了火及化学剂的用量，到达环保的纲的。

According to the sand filling tube model , research the blank off efficiency、enduring erosion ability and profile control efficiency; The single core flow experiment purports that: at the conditions of 20meter/D injection velocity and 0.5PV injection amount, the blank off efficiency keep above 40% after flushing 20PV.

采用填砂管模型研究了盐沉析体系的封堵效率、耐冲刷性和调剖效率；单岩心实验结果表明：当诱导剂注入速度为20m/天、注入量为0.5PV时，封堵率为66.67%，地层水冲刷20PV后封堵率保持在40%以上。

In this paper, the forecast model of scouring depth is conducted by neural network and BP neural networks.

利用神经网络和一些实测数据建立BP神经网络模型，进行冲刷深度的预测，用收集到的桥墩局部冲刷数据样本训练并测试BP神经网络模型。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
