A loss in volume will occur if infiltration takes place . 如果发生了渗润作用,水量就会减少。
It discharges three times as much water as the st. lawrnce . 它流出的水量有圣罗伦斯河的三倍那么多。
The quantity of water that can be drained out is called the specific yield . 能够抽出的水量称之为单位给水量。
It is important to get even distribution of water and good penetration . 灌水时水量均匀分布和充分渗透是很重要的。
In many cases, the important factor becomes the quality rather than quantity of water . 在许多情况下,重要的因素是水质而不是水量。
Evapotranspiration may deplete the soil moisture and rob supplies of ground water . 蒸发蒸腾作用能消耗土壤水分,减少地下水的水量供应。
Knowledge of historic and present water demands is needed to provide a factual base for predicting future water demand . 应了解过去和当前的需水量,以便为估算未来的需水量提供实施依据。
A few of the major chemical manufacturers are now offering solvent processes to the textile industry for scouring where little water is used . 有几家主要的化工厂现正提出在纺织工业中用水量少的精洗溶剂工艺规程。
Removal of water from reservoirs is more rapidly offset by inflow than is the replenishment of lake waters, which have lesser inflow . 从水库中汲的出水量,会很快地被流入的水量所补充,而湖泊的补充就要慢得多,因为它的流入量要少一些。
The safe yield of a ground water reservoir was defined by meinzer(1920)as "the practicable rate of withdrawing water from it perennially for human use. " 地下水库的安全开采量,据迈因策(1920)所下的定义为:“供人们长期使用的实际可能的开采水量。”
