这种气体是硫化氢，上升后与石灰岩裂缝中地下水的氧气混合。
This gas is hydrogen sulfide, rises up and mixes with oxygen in the underground water that sits in the cracks and fissures in the limestone.
世界上大部分的饮用水——适合饮用的淡水——是由地下水提供的，它储存在岩石的孔隙和裂缝中。
Most of the world's potable water—freshwater suitable for drinking—is accounted for by groundwater, which is stored in the pores and fractures in rocks.
地下水位是地层岩石裂缝和孔隙充满水的边界。
The water table is the underground boundary below which all the cracks and pores are filled with water.
水通常是自然形成的地下水，沿着岩石的裂缝渗出；不那么典型的是，水是通过从地表抽水而人工引入的。
The water is usually naturally occurring groundwater that seeps down along fractures in the rock; less typically, the water is artificially introduced by being pumped down from the surface.
地震的晃动使表土下沉，浅层的地下水受挤压会沿地裂缝上升至地表，形成喷沙冒水现象。
The earthquake shaking the surface subsidence, the shallow groundwater will be squeezed along the cracks rose to the surface, take a sandblasting water phenomenon.
改变了过去的手动曲线拟合为自动拟合，便于解释地下水力裂缝参数。
Besides, an automated type curve matching technique other than manual method is applied here to explain the underground hydraulic fracture parameters conveniently.
