Soil permeability is extremely important since it determines the rates of movement of water into and through the soil. Porous soil maintains oxygen levels in the root which helps in the respiration of the root and microbes that help in the growth of the plant. Moreover, the presence of ...
7.Peak concentrations and gradients for gentamicin aried considerably between animals, likely resulting from ariations in round window membranepermeabilityand rates of perilymph flow. 庆大霉素的峰值浓度和浓度梯度在动物之间的差异相当的大,这可能是由圆窗膜通透性的不同和外淋巴液流动 ...
The results suggest single layer barriers of the geotextiles alone have small effects on flow rates of water, but sand-geotextile combinations exhibited strikingly different behavior. In prewashed soil-geotextile combinations, the permeability decreased non linearly with increasing depth of soil above the...

A guide for estimating soil permeability rates was developed based on mean soil particle diameters that takes into account the wide ranges within commonly used soil textural classes and the influences of soil chemical properties, clay mineralogy, and other nonparticle size related factors affecting soil...

However, due to the aforementioned large difference between the consolidation rates with consideration of the non-Darcian flow in soft clay or not, it is better to consider the non-Darcian flow law for both the small and large stain assumptions. 展开 关键词: large-strain consolidation n...

Procedure for using undisturbed soil cores taken with the Kelley Soil Sampling Machine have been perfected whereby soil permeability and infiltration rates can be accurately measured. Soil cores were coated with hot paraffin in the field to allow transportation and storage without deterioration from the...
