The present work indicates the organic nf membranes and the inorganic nf membranes all have shortages, so develop composite nf membranes that have low cost, mechanically strong and thermally / chemically - resistant, easy to cleanout and good performances is a very important task. in this paper, the preparation of inorganic - organic composite nf membranes were presented. this composite comprise a porous sio2 / al2o3 support substrate, the pore diameters of which ranging from 10 to 15 nm, this inorganic support substrate having a polymer membrane which comprises an polyvinyl alcohol ( pva ) or polyamide ( pa ) densely deposited on at least one of the face surfaces thereof, the structural porosity of such pva and pa membrane ranging from 3 to 5 nm

Kongxi buried hill shows following features in the seismic profiles : the structures are asymmetric. there is flexural syncline on the east side and a monocline on the west side. asymmetric repetition of stratigraphic units is present in the drill wells and the dips of beds and faults are gentle. the permo - carboniferous system of both sides almost lie in the same slope and the events of cambrian or upper proterozoic are continuous from east to west. the phenomenas suggest that kongxi buried hill could be a thrust belt been traced which consists of reverse faults. the imbricate faults mainly effect pre - jurassic strata. there are obvious angular unconformity between jurassic - cretaceous system and paleozoic involved deformation of thrust. the thrust front in some place has cut off the beds of jurassic - cretaceous system. the structural style of the thrust structure changes along the strike of the kongxi buried hill
