1 Littoral's groundwater commonly keeps in the aquiferous system which is composed of multi-aquifer and feebleness dank layers, each layers' groundwater is exploited in various degree.

2 Water source includes aquiferous layer, river, water-eroded cave, goaf seeper, preferred faults with abundant groundwater.

3 Boilover accidents often take place in an aquiferous oil tank in the process of production and storage.

4 The utility model relates to a post shaped aquiferous porous foamed pot clay which has high performances of water suction and water dilution and high compression strength.

5 It is obvious that the the distribution of silica acid in interstitial water were affected by the contents of biogenic silica and aluminium, and aquiferous proportion as well.

6 The shaft sinking with the aid of grouting in Jingzhou Asbestos Mine indicates that sinking is possible in aquiferous karst area.

7 Text also explain climatically the reason why only these are lots of thatching in Yunnan zone based on the aquiferous capability of the couch grass and stability of stake.

8 The geochemical behaviour of heavy metals in river and its effect on shallow aquiferous system of both sides of the river are studied by theoretic calculation and experiments.
