摘要
借助于球极投影,定义出球极逆投影。在球极逆投影下,先将平面区域映射到球面上,得到球面方程的一种新的形式,再讨论了球极逆投影的性质。
According to the stereographic projection, its inverse projection is defined. Under the inverse ption, the region of a plane is mapped into the spherical surface, hence, an equation of the spherical surfobtained, and some characteristics of the inverse projection are discussed.
