Jade wares are an excellent carrier reflecting this concept. A detailed discussion on the plastic art of the jade sword pommel unearthed from M12, Xiaotianxi, Fuling District, Chongqing can clarify the characteristics of the times reflected in the artifacts and the symbolic meanings and cultural connotations contained therein. At the same time, based on the analysis of the shape and pattern decoration of the jade sword pommel, we can also see the close development of jade sword ornaments and social secular beliefs and ideals in the Han Dynasty.展开更多
Using astrometric techniques developed by Anderson et al., we determine proper motions （PMs） in the ~ 14.60 × 16.53 arcmin^2 area of the kinematically ＂thick-disk＂ globular cluster M 12.

The cluster＇s proximity and sparse nature makes it a suitable target for ground-based telescopes. Archive images with time gap of ~ 11.1 years were observed with the wide-field imager （WFI） mosaic cam-era mounted on the ESO 2.2m telescope. The median value of PM error in both components is 0.7masyr^-1 for the stars having V ≤ 20mag. PMs are used to determine membership probabil-ities and to separate field stars from the cluster sample. In electronic form, a membership catalog of 3725 stars with precise coordinates, PMs and BVRI photometry is being provided. One of the possible applications of the catalog is demonstrated by gathering the membership information of the variable stars, blue stragglers and X-ray sources reported earlier in the cluster＇s region.展开更多
