在印度、中国、美国等地，地下含水层被抽离的速度比自然补给还要快。
Groundwater aquifers are being pumped down faster than they are naturally replenished in parts of India, China, the USA and elsewhere.
地下水的渗透速度影响着其与岩石的反应速度，而地质构造、岩层厚度、岩石破碎程度及地下水的补给状况等则是影响地下水运动的重要因素。
Infiltration velocity of groundwater influences its reaction rates with rocks. Geological structure, strata depth, rupture degree and supply of groundwater are major influence factors.
