在學習蘇聯先進地質科學中,經常看到一些立體圖,其中如“礦產普查勘探方法”第423頁的錳礦投影圖,根據各鑽孔中所得的厚度及鑽網的平面位置,應用了斜軸側投影的方法,把它明顯的表現在一個富於立體感的投影圖上。這樣就可以使大家(即使沒有讀圖修養的人)能一目瞭然地看出這个礦床的厚度變化,對於礦床的研究是有所幫助的。在這裹將礦床立體圖的投影原理,以及在繪製這種立體圖的具體步骤
In studying the advanced geological science in the Soviet Union, we often see some perspectives, of which the projection of manganese ore on page 423 of the “Mineral Prospecting and Exploration Method”, on the basis of the thickness obtained in each borehole and the plane position of the drill network, Projection method, it obviously manifested in a full three-dimensional projection on the map. This will enable everyone (even those who do not read the map to cultivate people) can be clear at a glance to see the changes in the thickness of the deposit, the study of the deposit is helpful. In this package will cast the perspective of the projection of the three-dimensional map, as well as the specific steps in the drawing of this perspective
