纬线

Latitudes are the lines that go from east to west.

纬线是从东西线。

An equalarea pseudo cylindrical projection gather is constructed, in which the longitudes are hyperbola being symmetrical to the central meridian and the latitudes are parallel lines.

摘要构建了个纬线表象为平行于直线，经线表象为对称于中央直经线曲线，且面积没有变形投影集合，并得概括公式。
