被侵蚀的

Economics professor Pedro Arrojo-Agudo, who teaches at the University of Zaragoza in Spain, is using his academic expertise to battle a monster: the National Hydrological Plan, a $25 billion project that would build 120 dams on the Ebro River. The dams would submerge entire towns along Spain's second-longest river, displace tens of thousands of rice and fish farmers, and poison the wetlands of the river delta with salt.

在西班牙萨拉戈萨大学任教的经济学家培德洛E亚若杰阿古多（Pedro Arrojo-Agudo）运用他的专业知识，和一头大怪物「国家水文计画」奋力对抗，这是一项高达250亿美元的计画，将在伊布罗河上建立120座水坝，这些水坝会淹没西班牙第二大河沿岸的数个城镇、迫使数以万计的农夫和渔民迁徙，并使河口三角洲的湿地被盐侵蚀。

In the Butterfly Nebula the new camera shows subtler detail in gas clouds being eroded by stellar wind.

And near its lower reaches there is a long tailing-off which is almost certainly the result of material transported out to deep water after being eroded from the continental masses.

在这个地带的低处是很长的一段尾沙地段，基本上可以断定这个地段是大陆块体上侵蚀下来的物质被水冲到深水处形成的。

But the study that the cosmogenic 7Be is imbibed and intercepted by the cover materials on the soil surface is relatively less, which leads to a direct impact on the accuracy of the tracing results, the establishment and application of the tracing models.

：7Be具有环境微粒示踪价值，在示踪土壤侵蚀研究中有一定的应用，但是有关地被覆盖物对7Be截留吸收的研究目前还相当少，这直接影响了示踪结果的准确性、示踪模型的建立及应用。

The toxicity of spent potliner is discussed in this paper according to the research on main constitutes,microstructure,tiny section components,ash content and hydrating reactivity of SPL. The result indicates that the toxicity of SPL mostly rests with its leaching toxicity,contaminates in SPL are mainly dissolving fluorides and cyanides,these contaminates mostly come from electrolyze which infiltrate into the potliner and cause erosion,contents of dissolving F— and CN— in SPL are far more than the permitted discharge in national standard. SPL, which seriously does harm to eco-environment is classified as hazardous solid waste and should be detoxified as soon as possible.

本文从废槽内衬的物相组成、微观形貌、微区成分、灰分、水化反应性五方面研究了废槽内衬的危害性，结果表明，废槽内衬的危害性主要在于其浸出毒性，毒害物质主要是可溶氟化物和氰化物，毒害物质主要来自于电解质对内衬的渗透、侵蚀，废槽内衬中可溶F—和CN—的浓度远远高于国家标准规定的允许排放量，因此废槽内衬被认定为固体危险废弃物，严重危害生态环境，必须进行无害化处理。

Your Legacy Systems have been "Leap Frogged" by a Nimble Entrepreneurial Firm - This happens all the time and can cause an erosion of your customer base.

你的遗留系统已被&甩开&，由一个灵巧的创业公司，这一切发生的时间，并且可造成侵蚀，你的客户群。

F. On the other hand, as the gas with high oxidizability introduced to pre-reduction process, it will give a lower reductibility of iron ore and as the ore come to the final process the burden of the final reduction vessel will be heavier, the refractories of it will be corroded seriously and the campaign-life of it will be shorter.

终还原排出的煤气可以供预还原使用，由于排出煤气温度较高，需要降温才能供预还原炉使用，在此过程中煤气的物理热未被利用，这是目前熔融还原工艺能源消耗普遍大于高炉工艺能源消耗的主要原因；同时排出煤气氧化度较高，影响到矿石的预还原率较低，铁浴终还原的负担较重，终还原炉渣对炉衬的侵蚀严重，影响到铁浴终还原炉的寿命。

Culture security is defined that the functional order of the national culture system, mechanism, sequence based on national mainstream of core value,are free from interruption, erosion , destruction, and also including the integrality, organic whole of the national culture sovereignty, culture interest ,culture dignity and so on.

文化安全是指一个国家以主流价值体系为核心的各种文化体制、机制、秩序的运行常态及其所标示的国家文化主权、文化利益及文化尊严的完整性、有机性不被国内外不良因素所干扰、妨碍、侵蚀与破坏。

From left: blocks of icy debris, warmed by the sun, tumble down cliffs of the northern ice cap; swirling dust devils leave tracks on defrosting dune surfaces in the south; as polar ice recedes, the surface erodes in scalloped ridges; during spring in the north, sand dunes emerge from the blanket of frost; starburst patterns are created as ice warms into gas and expands, creating channels spreading out radially; when the gas breaks through the ice, it creates plumes and material is carried downwind.

从左侧起依次是：冰碎块，由于被太阳加热，从北部冰帽的悬崖上滚落；漩涡状尘暴在南部解冻的沙丘表面留下的轨迹；消退过程中，极冰在地面侵蚀出圆齿状脊；在北部的春季，沙丘钻出&霜毯&；星暴图案是在冰融化成气体并不断扩散时形成的，在此过程中形成的沟槽呈放射状向外伸展；冰从固态变成气态时产生的气羽流顺风飘散。

Because they have excellent resistance to E-glass fouling and have no pollution to fiberglass, they are used in sidewall of tank, bottom of tank and main channel of the tank furnace of fiberglass.

它以其优异的抗高温E玻璃侵蚀性和对玻璃纤维很小的污染，而被用在玻璃纤维池窑的池壁、池底及主通路等诸多部位，是池窑拉线工艺中最重要的耐火材料。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
