There are three popular map projections in Antarctica-Polar Stereographic projection, Transverse Mecator projection and Lambert Conformal Conic projection.

南极地区常用的地图投影方式有：极方位立体投影、横轴墨卡托投影、兰伯特正形圆锥投影等三种等角投影。

There are three popular map projections in Antarctica-Polar Stereographic projection, Transverse Mecator projection and Lambert conformal Conic projection. They are all conformal.

南极地区常用的地图投影方式有：极方位立体投影、横轴墨卡托投影、兰伯特正形圆锥投影等三种等角投影。

According to the selective principle of map projection and Guangxi Regional place and form, the normal secant conic conformal projection of Guangxi Region is designed in this paper.

根据地图投影选择的原则以及广西壮族自治区的地理位置和形状，设计了广西壮族自治区正轴等角割圆锥投影。
