摘要： In this paper, we've studied distributing characteristic of the paths in these graphs, put forward an idea of the nested rule on path distribution, and established a lat ice algebric structure of a covering of intervals. On the basis of this, we've established the partition theory and a reducible model of hierarchical structure.
