pore pressure coefficientとは 意味・読み方・使い方

Here, K expresses permeability coefficient expressing permeation resistance of the diffusion layer that is a porous body, ΔP indicates capillary differential pressure of force applied to aqueous liquid in a pore of the diffusion layer, D shows diffusion coefficient expressing diffusion coefficient of steam inside the diffusion layer, and Dd shows diffusion coefficient of steam in the air.例文帳に追加

但し、Ｋは多孔体である拡散層の透過抵抗を表す透過係数、ΔＰは拡散層の細孔中の液水にかかる力の毛管差圧、Ｄは、拡散層内における水蒸気の拡散度合いを示す拡散係数、Ｄｄは、水蒸気の空気中における拡散係数を示す。 - 特許庁

A pressure gauge, a flow meter and a temperature meter are installed in a ground water sampling pipe, thereby measuring the pressure in a flow in the ground water sampling process, the pressure when the flow is intercepted, and the flow to measure the pore water pressure and a coefficient of permeability simultaneously with sampling the ground water.例文帳に追加

地下水試料採取管路には圧力計、流量計及び温度計が取付けてあり、地下水採取過程でのフロー中の圧力とフロー遮断時の圧力及び流量を計測し、間隙水圧と透水係数を地下水試料の採取と同時に計測できる。 - 特許庁
