摘要
在这份报纸，我们定义 quasiconformal mappings 的二个班，并且由模块的方法学习他们的盖住的性质。我们获得一些新结果。同时，我们给新方法证明在凸的保角的 mappings 上盖住定理的 Koebe 1/2。
In this paper we define two classes of quasiconformal mappings, and study theircovering properties by methods of module. We obtain some new results. In the meantime,we give new methods to prove Koebe 1/2 covering theorem on convex conformal mappings.
