Other AbstractAs a new-type astrmetric instrument, for having high measuring precision and multiple observation values, it can adapt the requirement of present research, and resolve the difficult puzzle which existed in other branch of astronmy before with its observation value. LLMC-Low Latitude Meridian Circle, a optical telescope on ground, attached the scientific CCD detecor, can gain the absolute position of objects which include extraglactic, star and minor planets, derive the relative luminosity of stars and get the annual proper motion and parallax with pricision of 0.8mas/year and ±2mas correspondly. In order to full used of thoes measuring values providing by LLMC+CCD, we should find some research targets which fit for this instructment. So in this paper, we proposed some of them and gave the description of probablity and demended for its realizing. (1) To establish the semi-inertia celestial refrence which contain thousands of extraglactic objects, millions of star and some of minor planets. Meanwhile, to construct a dynimic refrence with observation of asteriods. (2) To provide the valid observation data for the thoes research including solar system dynimic, the Galaxy constructure and knimatics and some realms of Astronphyesics. (3) For this instrument is on ground, its measurement contain the vary quantity of the earth rotation and constructure, so we can study the change of the rotation axis of the earth in space and continental drift. (4) If LIMC+CCD can cooperate with Hipparcos and LMOST (Large Sky Multi-Object Fibre-Spectrscopy Telescope), we believe that some questions can be resolved, for example, Hipparcos star catalog's zero point correction.
