纬线

Latitudes are the lines that go from east to west.

纬线是从东到西线。

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.

摘要构建了一个纬线表象平行于赤道直线，经线表象于中央直经线曲线，且面积没有投影集合，并得到一组概括公式。
