基本解释

英汉例句

Considering the relative permeability of lining and surrounding rock or soil, the tunnel is assumed to be partially sealed.
考虑衬砌和围岩（土）的相对渗透性，隧洞处于半封闭状态。
It is normally assumed that the effective permeability is the same for all fluids at 100 per cent saturation, 'this permeability being denoted as the permeability of this porous medium.
通常假设所有流体在百分之百饱和时的有效渗透率是相等的，某一渗透率特指某—多孔介质的渗透率。
However, in most simulation calculations of gas reservoirs the porosity and permeability is assumed as a constant so that the result of simulation calculation is higher than the real situation.
而在绝大多数气藏模拟计算中，都假定了孔隙度、渗透率参数保持常数，以致模拟计算结果比实际偏高。
