中文摘要:

      利用Building理论获得一种计算某些三角几何的基本群的新的方法．这种方法能够容易地计算出无限多有限三角几何的基拓扑基本群．

英文摘要:

      In this paper , depending on the theory of buildings, we obtain a kind of method completely different from past ones, to compute topological fundamental groups of some triangle geometries. This method will enable us to easily compulte topological fundametal groups of infinitely finite triangle geometries.
