Starting in May 1995, SCAP uses the 60/90 cm f/3. 0 Schmidt telescope equipped with a 2048 * 2048 CCD, making asteroid searching observations in non-photometric nights which are not suitable for high-precision astronomical photometric observations, as well as in the short period of dark time outside the astronomical twilights. Asteroid information is also extracted from general photometric observation data when applicable. The telescope locates in Xinglong Station of Beijing Astronomical Observatory, which is about 180 km north - east of the Beijing city.展开更多

Orogenic belts, having experienced the most intensechanges of geotherm and mechanics in the lithosphere, are the important research object in thestudy of continental dynamics. For this reason, the study of orogenic belts forms a hot and dif-ficult point in the geological society and the concentration of efforts is needed for overcomingthis difficult point.
