摘　　要：在有界区域上 ,仿射拉伸是极值映射 ;而在无界区域上 ,以往很多例子说明仿射拉伸未必是极值映射 .本文的目的在于刻划一些相当广泛的区域 ,使得仿射拉伸在这些区域上是极值的 .In the bounded region, affine stretching is an extremal mapping. In the unbounded region, however, many examples show that affine stretchings are not necessarily extremal mappings. This paper delineate a quite extensive regions in which the affine stretchings are extremal.

关 键 词：仿射拉伸 极值映射 拟共形映射 区域刻划
