The identification of waste commodity package can be achieved by identification sign,and the identification sign conceptual model of waste package and its web scheme are presented.

The identification signs of karstification in syndiagenetic stage,Caledonian Epidiagenetic stage,Early Ercynian Epidiagenetic stage and Epi-Hercynian burial stage were studied in detail by the means of core observation,thin section analysis,paleontology and geochemistry on the basis of the information of regional geology,well drilling and well logging.

The identification marks of sequence boundaries, maximum\|flooding surface and transgressive surface are all different from that of marine strata.

This paper presents the study of the igneous rock lithofacies and seismic recognition marks,the discussion of the relations between igneous rocks and oil-gas reservoirs,pointing out the favorable zones of igneous reservoirs.

Artificial mark recognition,including mark area recognition and mark pattern recognition,is a significant process of augmented reality.

A method to realize augmented reality based on artificial marks is presented,including four steps: mark recognition,vertex abstraction,3D-register and camera synthesis.
