These two things are what we will study in sectionⅢ. We call them GS and PS. In this section we will study the impact of the two and the relationship between them. Of course, there are some other ways to observe the problem. One of them is to consider the period and the distribution of eigenspace. These are what we will study in sectionⅡ.
