Based on grain size analysis and core observation, main deposition systems have been recognized, including incised valley infilling system, lacustrine system, sublacustrine fan system and delta system. Among them, valley infilling system occurs in later lowstand system tract distributed in northern area, and sublacustrine fan system lies in southern area in early lowstand system tract.

通过粒度分析和岩心观察，认为中油组主要沉积体系包括侵蚀沟谷充填沉积体系、湖泊沉积体系、湖底扇沉积体系、三角洲沉积体系，其中低位侵蚀沟谷主要分布在研究区北部，主要发育在低位体系域晚期，湖底扇主要分布在研究区南部阿克亚苏地区，主要为低位体系域早期沉积。

The influence of environmental factors with different sulfate types (Na2SO4, MgSO4) and temperatures (5, 20 ℃) on various kinds of sulfate attack of cement mortars was studied, and the special environmental factors for the formation of thaumasite were confirmed.

研究了硫酸盐种类(Na_2SO_4，MgSO_4)及温度(5℃，20℃)等影响因素对水泥砂浆硫酸盐侵蚀类型的影响，以明确碳硫硅酸钙型硫酸盐侵蚀的特性环境条件。

Apply Lean/Six Sigma tools to improve process capability to reduce CoF for all traditional CoF accounts along with margin erosion, billing quality, unbilled, and receivables.

应用精益/6-Sigma工具提高过程能力减少传统意义上的失败成本、成本侵蚀、开票质量、未开票以及应收账款的失误造成的成本侵蚀。

At the same surface soil velocity, the wind erosion modules under plough tillage are 3～8.2 times of those under no-tillage. And the wind erosion modules decrease with the increase of years of no-tillage.

在同样风速条件下，翻耕地土壤风蚀侵蚀率是免耕地的3～8.2倍，且随免耕年限的增加，土壤风蚀侵蚀率呈现递减的趋势。

The corrosion resistance of chloride ion for concrete admixed with fly ash and slag is tested,and the corrosive surroundings of steel reinforcement concrete in splashing marine zone and fluctuating water level zone in the south of China are simulated.

东南沿海的海工钢筋混凝土结构物破坏的主要原因，是海水中氯离子对结构物的侵蚀；北方则是结构物受冻融破坏和氯离子侵蚀[1] 。

A thermal model of 2D FLAC is used to simulate the chloride ions diffusion in carbonized concrete and un-carbonized concrete, because they have the same control equation.

分析总结了混凝土中氯化物的来源和对混凝土的侵蚀机理以及氯离子侵蚀的模型，分析了氯离子对钢筋锈蚀的影响。

The break-off and cumulates of subducted slab would give rise to the upwelling of mantle material and then thermal -chemical erosion of lithospheric roots happened.

俯冲板片断离及在深部地幔中的堆积，必然引起地幔物质的对流，从而产生地幔羽，上升的地幔羽对岩石圈底部发生热侵蚀和化学侵蚀，并在薄弱地带上升喷出地表或侵入在地壳浅部，形成了广泛而强烈的岩浆作用。

As the concentration of FeO increasing, the rate of decarburizing and reaction-dissolving of refractory rises sharply. Meanwhile gas production rate of reduction reaction is increased and motion and foaming of molten slag are also speeded up. The corrosion feature of refractory containing graphite carbon is that the most severity area is slag level (interface of slag-gas phas -refractory) and slag-metal interface comes second, and the lowest corrosion rate is the area of iron-bath.

熔体的组成、温度及熔体与耐火材料间的相对运动对耐火材料的侵蚀产生着很大影响，而熔渣中FeO浓度是最主要的因素，FeO浓度提高，使耐火材料脱碳和反应熔蚀速度呈直线上升，熔体中还原产生气体量增加，熔体涨泡及运动速度提高，这些作用都加快了熔体对耐火材料的侵蚀。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
