At last, the design method with correlated formula of cast-in-situ bored piles with grouted toe were given out and parameters which govern the formula were also discussed. Some problems which should be concerned in grouting construction were discussed.

文中提出了不同土层中桩底灌浆桩竖向承载力的设计方法，给出了相应计算公式，对各种情况下的参数取值提出了建议，并对桩底灌浆施工过程的关键环节和需注意的问题进行了讨论。

A recent study suggests, however, that permafrost ices below the surface of Mars may have altered the effects of impact on it.

但是，近来的研究表明，火星土层表面下的永久冻结冰可能改变了这种冲击效应。

The nanocomposites were exfoliated at 3wt% content of pristine clay relative to the amount of polystyrene. We employed two surfactants for the montmorillonite: cetylpyridinium chloride and the CPC/α-CD inclusion complex. Prior to polymerization, each surfactant intercalates into the layers of the pristine clay dispersed in water.

奈米复合材料在3wt％的黏土含量下达到脱层的结构，我们使用两种插层剂来改质黏土：CPC与CPC套上环糊精错合物，聚合反应前将每种插层剂预先在水中进行插层於黏土层间。

In addition, mathematical models describing the changes of soil water contents with time within 30 cm, 60 cm, and 90 cm depth were also proposed, with which the temporal dynamics of soil water in the intercropped maize fields could be well predicted.

并建立了0～30、30～60、60～90及0～90cm土层土壤含水量随时间变化的数学模型，以此来预测试验条件下套作玉米带土壤水分随时间变化的动态。

The results indicated that CTMA+ and Am intercalated into the lamellae of bentonites successfully.

结果表明， CTMA+和Am已柱撑进入膨润土层间。

Tombs were also fenced by stones around and covered by stone bars or stone laths, on which soil tightly covered, and then piled some stones again over the soil.

葬墓距地面较浅，墓穴窄小，周边多以石块或石板砌成，上面以石板或石条封顶，然后夯土，并在土层上面堆积石块，因此我们称此为&积石塚&。

At harvest 9.2%–10.9% of labeled urea was leached below 40 cm soil layer.

大白菜收获时9.2%～10.9%的标记尿素被淋洗到40 cm以下土层。

Of the nitrogen supplied as inorganic fertilizer is lost under two treatments, and 30% under FAR and 26% under RAR of which leaches to depths over 40 cm of soil profile. It is therefore necessary to understand whether leached nitrogen is utilizable by deep-rooted crops.

两种施肥处理均导致65%左右的氮素损失，其中习惯施氮和推荐施氮分别导致30%和26%的氮素淋洗到40 cm以下土层，为此有必要种植蔬菜后利用深根系粮食作物吸收土壤下层氮素来降低蔬菜生产对环境的影响。

One reason why AIFU has the best spatial coupling effect is that it has a smaller evaporation area, thus its wate loss by this way is much smaller that traditional full irrigation; leching of fertilizer nutrients is much less than traditional irrigation because fertilizer and irrigating water exists in different furrows, the residual fertility exists in above 60 cm soil profile.

水肥异区交替灌水为一种局部灌水方式，其能够提高水分利用率的原因是可减少蒸发面积，从而减少灌溉水的蒸发损失；对养分的淋溶损失少，使肥料养分主要存在于60cm以上土层。

The method to determine ultimate lateral resistances based on soil strength parameters was established by analyzing the failure mode of liquefying saturated strata.

通过分析土层在液化过程中的破坏模式，提出了依据弱化土强度参数确定其水平极限抗力的方法。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
