In this paper, the advance of the research which took in recent thirty years for the constitutions and the kinematics of the stellar group in the Goult Belt near the sun are reviewed. Some theoretical models for the kinematics of the Galaxy are discussed. And We put forward also the primary proposal to research these parts with the FK6 catalogue system.
The paper reviews the advance of the research work of the zero level theory of information, describes the concept of zero level information, its form and characteristics, its communication range and the pattern structure,the collective form and the method of process and investigation, and how to emphasize the zero level information work.
