1·Darcy's law can be applied to unsaturated flow subject to certain restrictions on seepage velocity.

达西定律也适用于渗透速度有一定限制的非饱和水流。

2·It is proved through experimental research that the Darcy law should be revised to adapt to high seepage velocity.

研究表明，在渗流速度较大时应对达西定律加以修正。

3·The sensitivity of seepage velocity is effected by the external variables; and the coal and gas outbursts are also discussed.

讨论渗流速度对外部变量的敏感性和煤与瓦斯突出的突发性。

4·The seepage velocity in peak stress decreases with the increase of confining pressure, and indicates obvious linear relationship.

煤样的峰值渗流速度随围压的增加而减小，呈现较明显的线性关系。

5·Equations of steady drawdown, seepage velocity, quasi steady time and ideal well distance were obtained through analytic seepage equation.

通过分析理论解，从中得出稳态降深方程、稳态渗流速度方程、准稳态时间方程和理想井间距方程。

6·The relative curves of the ratio of transient permeability to initial permeability with the injected fluid volumes or seepage velocity are like a character S.

渗透率比值与注水孔隙体积倍数或渗流速度的关系曲线均呈“S”形；

7·The seepage velocity of briquettes is sensitive to axial pressure and axial strain, but it is sensitive only to transverse strain and volume strain for row coal.

型煤的渗流速度对轴向压力和轴向变形最敏感，而原煤的渗流速度对体积变形和横向变形比较敏感。

8·The increasing rate of the gas seepage velocity of outburst coal samples was decreasing with the increase of gas pressure and reaches to a constant value at last.

而突出煤样的瓦斯渗透速度增加率则随着瓦斯压力的增大而减小，最终趋近于一恒定值附近。

9·The experimental results are as follows. The gas seepage velocity of outburst coal samples increase with the increase of gas pressure under fixed axial and confining pressures.

试验结果表明：在轴压和围压固定的情况下，突出煤样的瓦斯渗透速度随着瓦斯压力的增大而增大。

10·The seepage velocity through lakeshore and lake bottom interfaces under different lakeshore inclinations were discussed by experiments in soil tank and model simulations using MODFLOW.

利用土槽试验和MODFLOW模型模拟研究了不同岸坡倾角下地下水入湖时在入湖交界面处的渗流速度分布规律。
