沙丘

Like hillocks of sand, the Arabs say, soft and downward-slipping with a long slope.

如阿拉伯人说的，那象是些沙丘，柔和地、成长坡地下降。

The downs, the extent of which was large, were composed of hillocks andeven of hills, very irregularly distributed.

这片沙丘非常广阔，是由许多山石，甚至还有一些小山组成的，分布得很不平均。

Hokey religions and ancient weapons are no match for a good blaster at your side, kid

但是老班住在沙丘C区，是个奇怪的隐居者

Families purchased a sand dorm outside the walls of Jaffa in 1909 to begin a Jewish neighborhood.

年 66个家庭在约帕城外向阿拉伯人买下一片沙丘，开始了第一个犹太垦殖区，发展成今日的特拉维夫。

THIS story is from the sand-dunes or sand-hills of Jutland, but it does not begin there in the North, but far away in the South, in Spain.

这是尤兰岛许多沙丘上的一个故事，不过它不是在那里开始的，唉，是在遥远的、南方的西班牙发生的。

The central plains area of 603.25 square kilometers, accounting for a total area of the county's 60.4 percent, Jingshan railway north of the ground at an altitude of 50 meters height above the hills locally exposed, relatively flat terrain, the ground elevation Jingshan railway generally south of 30 -50 m, because of wind and rivers, sand dunes occur more frequently valley.

中部平原区面积603.25平方公里，占全县总面积的60.4%，京山铁路以北，地面高程在海拔50米以上，局部有山丘出露，地势较为平坦，京山铁路以南地面高程一般在30—50米，由于受风沙影响及河流切割，沙丘沟谷出现较多。

This showed that capacity of water-holding in biological soil crusts were obvious improve,and effected precipitation permeate or water second distribute process.The study results of"fertile islands"formation mechanism in biological crusts showed that biological crusts layer cover could increased nutrients content for below sand soil through precipitation permeate washing,and it promoted plants assimilate more nutriment.The matter import ways of biological soil crusts fertility island had many ways,including the effection of living macrobiotics metabolism in crusts levels,wind-sand flow of near surface,dust deposition and plants decomposition course,etc.Source of particle matter in biological soil crusts was wind-sand flow of near surface,and not dust deposition.Biological crusts layer cover had preserved effection for nature water content in 0-5cm soil layer,compared with the sand of no biological crusts layer,effecting precipitation permeate,and could not obvious restrained from the water evaporate process indoor experiment.

生物结皮层肥岛形成机制的研究结果表明：生物结皮层覆盖能够通过降水淋溶作用而增加下层土壤养分的含量，进而促进植物对养分的吸收；生物结皮层养分输入有结皮生物代谢、降尘、风沙流和植物分解矿化作用等多(来源：A73e3B3eC论文网www.abclunwen.com)种途径，但生物结皮层的颗粒物质来源主要是近地表风沙流，而不是大气降尘；生物结皮层覆盖对0-5cm土层自然含水量有一定的保护作用，并影响降水向深层渗透，不能有效的阻止表层水分的蒸发进程；研究表明采取人工促进技术能够在流动沙丘上形成生物结皮层，实现流动沙地的快速治理。

Why is marram grass planted on sand dunes?

为什么要在沙丘上种滨草？

The collapse which Bloom ascribed to gastric inanition and certain chemical compounds of varying degrees of adulteration and alcoholic strength, accelerated by mental exertion and the velocity of rapid circular motion in a relaxing atmosphere, Stephen attributed to the reapparition of a matutinal cloud (perceived by both from two different points of observation Sandycove and Dublin) at first no bigger than a woman's hand.

布卢姆暗自同意斯蒂芬的论点。布卢姆认为斯蒂芬之所以晕倒乃是因为他胃囊里空空如也，以及搀水量与酒精度数各不相同的化合物在作怪。这是始而精神紧张，继而又在松弛的气氛下疾迅地旋转这一剧烈的运动所造成的。斯蒂芬却把它归因于起初还没有女人的巴掌那么大的晨云再次出现（他们二人曾从不同的地点--沙丘与都柏林，目击到那片云彩）。

The spice! Dune was noteworthy only as the source of melange, the only source .

香料！沙丘的名声完全来自香料的产地，唯一的产地。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
