纬线

Latitudes are the lines that go from east to west.

纬线是从东到西的线。

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.

摘要构建了一个纬线表象于赤道的直线，经线表象对称于中央直经线的曲线，且面积没有变形的投影集合，并得到一组概。
