地下水提取 | groundwater extraction The process, deliberate or inadvertent, of extracting ground water from a source at a rate so in excess of the replenishment that the ground water level declines persistently, threatening exhaustion of the supply or at least a decline of pumping levels to uneconomic depths (精心策划或随意自地下水源以超过地下水补充的速率汲取水的过程,会造成地下水位持续的下降,使得水源有枯竭的危险,或至少使水位下降至不符合经济效益的抽取位置。) |
水提取 | water extraction Pumping of water for different purposes (i.e. agriculture, land reclamation, domestic and industrial use, etc.) (抽水用于不同目的(如农业、土地复垦、家庭和工业用途等)。) |
泥煤提取 | peat extraction Peat is obtained from peat bogs by cutting it from the earth; it is then formed into briquettes, which can be used as fuel. Peat may be found in layers several metres thick. In some countries peat-fired generating stations for electricity are in use. Peat is also used as a soil conditioner (从泥炭地中提取泥炭,然后形成煤球,可作为燃料。泥炭层有数公尺厚。在一些国家电站作为发电能源投入使用。泥炭也被用作土壤保护素。) |
滤取 | leaching 1. The process of separating a liquid from a solid - as in waste liquid by percolation into the surrounding soil. 2. Extraction of soluble components of a solid mixture by percolating a solvent through it. 3. To lose or cause to lose soluble substances by the action of a percolating liquid (1. 从固体(如废液渗透到周围土壤)中分离液体的过程。 2. 通过使用溶剂溶解,从固体混合物中提取可溶性成分。 3. 通过滤掉溶液失去或使失去可溶性物质。) |
