查询词典 soils

Their surging exploitation of resources threatens to exhaust or unalterably spoil forests, soils, water, air and climate.

他们对资源的过度开发、利用可能破坏或者耗尽森林、土壤、水以及气候，并且难以恢复。

How to calculate the penetration was proposed according to the results of numerical analysis while the compression of underlain soils can be estimated by integration method. After comparing the results obtained from stress dispersion method and equivalent solid mass method, both recommended in the code, the latter was proven to be more accurate.

桩端平面以下土层的压缩量则根据分层总和法计算，在比较了规范推荐的应力扩散法和等效实体法之后，本文认为等效实体法计算桩端平面以下土层的压缩量更准确。

The site is underlain by deep, weak foundation soils

内华达州交通部之所以选用这种加筋土桥肩，不仅是因为可以省钱，更因为这改进了设计。

The main reason for this growth is that MSE abutments generally cost substantially less than conventional concrete abutments, especially at sites underlain by weak or compressible soils where piles are eliminated by true MSE abutments.

SME在桥肩加固中应用增加的主要原因是和常规混凝土桥肩相比SME桥肩更经济，尤其场区地基土比较软弱或是高压缩性土，难以在实体桥肩选择桩基础。

Mechanical behavior and modeling of partially saturated soils under undrained condition has drawn much less attention.

尽管有些学者业已提出力学模型以描述部分饱和土壤之力学行为，但对於部分饱和土壤的不排水力学行为则鲜有著墨。

Formulae for the calculation of undrained shear strength and total stress strength index of normally-consolidated soils under partial drainage are derived.

建立了剪切时存在部分排水条件下土的抗剪强度与总应力强度指标理论式，分析了部分排水时土的抗剪强度确定与模拟问

The analytical solution to the progressive destructive normalized undrained strength of anisotropic natural soils is derived.

自然界尤其是天然沉积的土体是由许多颗粒在相对静水中沉积而成，由此导致一个K0固结过程。

Two techniques were compared that uses the UV absorbance at 280nm of 0.5mol/L K_2SO_4 extracts of fumigated and unfumigated soils and fumigationwaterlogged incubation to estimate the concentrations of nitrogen in the SMB.

用氯仿熏蒸-0.5mol/L的K2SO4直接浸提，280nm紫外比色法和熏蒸-淹水培养法测定了20种有机质、全氮和速效氮差异较大的土样的土壤微生物量N。

Over a 20-year period there was no increase in soil water content in the grazed grassland at depths of 2～9.9 m. There was a small increase(0.5～3.7 mm/a) in soil water content in the protected grassland, however the slow rate of increase suggests that at least 150 years would be needed for ungrazed grassland soils to regain water content similar to that present prior to planting trees. Recharge of deep soil moisture was faster in cropland(15 mm/a), but at this rate it would still take about 40 years to restore cropland soil water content to pre-plantation conditions.

结果表明，人工林死后的放牧荒坡在20a的时间里，其土壤水分没有补偿；人工林死后的保护草地土壤水分有微弱恢复迹象，但年恢复速度在0.5～3.7 mm之间，以这样的速度恢复到持续放牧荒坡的土壤含水量，至少需要150a以上；林后农地土壤含水量有恢复趋势，年平均恢复速度为15 mm左右，其土壤含水量要恢复到持续农地当前的水平，大约需要40a的时间。

TGGE method was applied to determine the relative genetic complexity of microbial communities in uninoculated and inoculated soils.

采用PCR-TGGE方法对生物强化过程中降解菌以及土著微生物的变化动态进行了研究。

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。
