[地质]含水层
1、shallower aquifers───浅层含水层
1、Water does not remain immobile in an aquifer but can seep out at springs or leak into other aquifers.───水在含水层中并不是静止不动的，而是会从泉水中渗出，或渗入其他含水层。
2、Though forbiddingly dry, the Simpson Desert has aquifers and floodplains that make parts of it ideal livestock-grazing country.───不过，尽管辛普森沙漠干燥得令人可怕，但它也拥有含水土层以及泛洪平原，足以成为放牧的理想国度。
3、The lower one, underlying the marine clay, contains several artesian aquifers used for drinking and economic purposes.───较低的一层在海生粘土下面，蕴HanZhuo几处用于饮用和商业用途的自流地下蓄水层。
4、These aquifers became saturated more than 10,000 years ago and are no longer being recharged.───这些含水层在一万多年前就饱和了，现在不再重新补充水分了。
5、In the name of progress, forests have been denuded, lakes poisoned with pesticides, underground aquifers pumped dry.───以发展之名，森林被砍伐一光，湖泊充满了杀虫剂，地下水抽空了。
6、Beneath the Sahara are huge aquifers, basically a sea of fresh water, that's perhaps a million years old filtered through rock layers.───下面是巨大的含水层，基本上是一片淡水的海洋，那可能是经过岩石层过滤的，已经有一百万年历史。
7、Just as serious is the depletion of the aquifers on which farmers depend.───农民们脚下的含水层损耗同样严重。
8、It was the result of villagers pumping up groundwater from ever deeper aquifers.───原因是村民从更深的蓄水层中抽取地下水。
9、An early hypothesis by Chakraborti holds that the arsenic is associated with iron pyrites and enters the aquifers by an oxidation process.───加卡波狄较早提出的一个假说认为，砷与黄铁矿结合并透过氧化作用进入含水层。
1、They collected core samples from freshwater aquifers in the US that overlie potential CCS sites and then studied their reaction to exposure to CO2 over the course of a year in the laboratory.
2、Aquifers could be used as carbon stores, if they could be made gas-tight.
3、These aquifers were created during the Pleistocene epoch, between 12,000 and 2.5 million years ago, and lack the organic carbon that is needed for arsenic to leach into water.
4、And in Africa, the aquifers barely recharge at all.
5、Though forbiddingly dry, the Simpson Desert has aquifers and floodplains that make parts of it ideal livestock-grazing country.
6、Chemistry of actinides in natural aquifers, migration behaviour of radionuclides and natural analogue study are mainly discussed.
7、Whales, forests, and aquifers have been treated in the same way.
8、There are three types of aquifers: perched, unconfined, and confined.
9、Aquifers are located and drilled into, so releasing the water trapped in the pockets.
