滤床 meaning in Chinese
filter bed
filtering bed
Examples
- The pond had recycle filter apparatus in which sand was biofield bed and air - pressed was powered
并且对该鳖池的结构、滤床的熟化、再生、净化能力、应用管理做了初步的研究。 - ( 3 ) the blockage of filtering bed and the thickening of the argitan can cause the change of hydrodynamic properties in the filtering bed , which leads to the decrease of water quantity
( 3 )滤床堵塞和泥膜增厚可能产生滤床中水动力特征的改变，会产生非饱和流导致出水量的衰减。 - The researches indicated : ( 1 ) the seepage flow field of infiltration diversion is characterized by three - dimensional , saturated and steady flow . there is the close hydraulic relationship between the river and the groundwater in the filtering bed , and the groundwater is confined
研究表明： ( 1 )渗滤取水的渗流场具有典型的饱和三维稳定流特征；渗滤取水滤床中地下水与河流的水力联系比较紧密，滤床中的地下水处于承压状态。 - ( 4 ) the maximum water quantity becomes greater , the better is the filtering bed permeability , the higher the river hydraulic conductance , the higher the river level , the larger the water - collecting area and the bigger the distance between collecting pipes . the water quantity varies directly with drawdown
( 4 )滤床的渗透性能越好，河床水力传导系数越高，河水水位越高，取水面积越大，取水管之间的间距越大，则最大取水量越大；水位降深与取水量成正比关系。
