摘要
作者在《地图》杂志1990年第4期上的论文中,提出了地图投影的具有标准线形状的几乎所有新类型,其中包含着一组新的伪圆柱投影。为了确定这组投影所含因式f(λ)的具体形式,本文考虑引进地图投影变形性质的两个参数,即面积比P和纬长比n。由此可建立实际的新投影。
The author has found that aimost, all new families of mapprojections possesses standard shape in a paper in CARTOGRAPHY No.4 1990 and it implies a now set of pscudo-cylindrical projections. For determination the concrete form of factor f(λ) in this new set, this paper considers that two kinds of distortion property in projection, i. e., P, the proportion of area and n, the proportion of paralled, can be the parameters used to build new projections.
