低纬子午环配备科学CCD后的课题目标

What Tasks can be Done After the LLMC is Equipped With a Scientific CCD

针对低纬子午环配备科学ＣＣＤ后的观测能力，叙述了该仪器观测的课题目标：为建立准惯性天球参考架提供充分的观测数据，为建立动力学参考架和太阳系动力学研究提供天然卫星和小行星的高精度数据，为银河系结构和运动学研究提供必要的数据，为某些天体物理课题研究提供有用的数据，为地球动力学和天文地震研究提供基本的测量数据。将来编制观测纲要时，会兼顾到这些方面的需要，合理安排，以求充分发挥该仪器的作用。

After the LLMC is equipped with a scientific CCD, the following tasks can be made. First, the instrument can provide the positions of nearly ten thousands extragalactic objects, and the positions and proper motions of several million stars as faint as 17 5 mag to construct a quasi-inertial reference frames. Second, the instrument can provide high precision observations of some natural satellites and asteroids to construct a dynamical reference frame and to serve for the study of the solar dynamics. Third, the instrument can provide some information for the study of the Galaxy and some astrophysical topics. Last, the meridian circle can provide some information on the dynamics of our earth and the earthquake.
