Our stuc1 indicates that the majority of the granites in Naniclan-Hechi metallogenetic belt belong to POG, while the later stage alaskite belongs to RRG+CEUC. The granites were formed at the stage of structure transformation from postorogenic phase to intraplate setting. But the major structural environment is steady regional extension. The formation age for the granites represents the time of this transformation, and this translation environment is favored for large-scale metallogenesis.

When the viewpoint is changing quickly, the rendering algorithm ignores some details of the diffuse component, otherwise the scene is rendered more precisely. The Specula highlight is dependent of the viewpoint, it must be processed in real time. We present an algorithm to get rid of the area that does not contain specula highlight quickly and calculate only the area that contains the specula highlight. In order to calculate the specula reflection and refraction component, we presented a new raytracing algorithm based on the environment map transformation. The environment maps are constructed at the sample points of the scene in the preprocessing phase. We add depth information in the environment maps and generate the exact reflection and refraction intensity with the transformation of a few pixels.

The results showed that plastic deformation at both -70℃ and 180℃ made the dislocation density of AISI304 stainless steel increase with the increase of deformation. Martensite phase transformation was induced for deformation at -70℃, whereas it was not at 180℃. As the dislocation density increased, the breakdown potential of AISI304 stainless steel's passive film became a little more positive. As martensite phase content increased, it became more negative and pitting corrosion resistance decreased.
