Leaning Tower of P is a tilt reason is because of its specificity of the foundation soil below caused.

比萨斜塔之所以会倾斜，是由于它地基下面土层的特殊性造成的。

In soil drying development, the relationship between the soil layer water storage and the cumulative relative water loss was expressed reliably as a logarithmic linear equation.

干旱过程中，土层贮水量和累积相对失水量之间的关系可以用对数线性方程表示，将方程的斜率转换为取值在[0，1]区间的指数D，可以定量表达土壤干旱程度。

It is assumed that potential sliding surface of the soil in the back of the retaining wall is composed of logarithmic spiral arc and line.

假定挡土墙后土体潜在滑裂面由对数螺线滑动面和平面组合而成，根据挡土墙后土体薄层单元的平衡条件推导出粘性土层主动土压力的计算公式。

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。

The compaction effect of geogrid with marlite method, soil bag with marlite method, replaced backfilling clay method, which were used in the swelling rock slope of the Luwangfen test Region of middle-route of South-to-North Water Transfer Project were studied on the different conditions.

比选、研究了在不同碾压机具、铺土层厚、碾压遍数等条件下，土工格栅＋泥灰岩开挖料、换填黏性土料、土工袋+泥灰岩开挖料等三种不同处理措施的压实效果。

In all fertilization treatments, the mean mass diameter of WSAs was larger in 0-10 cm than in 10-20 cm soil layer. Compared with non-fertilization, long-term fertilization increased the MMD of WSAs, and organic manure was superior to chemical fertilizers.

各处理0~10cm土壤水稳性团聚体平均质量直径均大于10~20cm土层；自然土壤的团聚体MMD显著高于同层次耕作土壤，长期施肥处理MMD大于无肥对照，有机物质培肥处理明显高于化肥处理。

From many experiments conducted by the author on the dynamic behavior of soil inrecent years it has been found that the propagation velocity of elastic wave,shear modulus andthe coefficient of subgrade rigidity in homogeneous soil tends to vary with depth.

近几年来，作者在对土的动性能所作的多次实验中，发现匀质土中弹性波的传播速度、剪切模量、地基抗压刚度系数有随土层深度而变化的现象。

The movability of totalP,inorganic P and Olsen-P to deeper layer was descended with soil depths.

土壤中总磷、无机磷和Olsen磷在土壤剖面中向下移动性随着土层的加深而减弱。

The soil nutrient status (0~40 cm) and their fruit quality were tested respectively in 2002 and 2003 from 4 Newhall Navel Orange orchards of 3-gorge area.

2005年测定了三峡库区4个纽荷尔脐橙园0~40 cm土层的土壤营养状况，分析了相应果园2003年纽荷尔脐橙果实的主要品质。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
