岩组图的制作一般包括作散点图,加绘等密线和必要的转图,是件很费时间的工作。目前,这些工作虽能用电子计算机代替手工操作,但不总是具备方便条件的。本文提出的新方法包括投影点的标绘,投影面的转换和圈定等密线等一套完整的作图方法,它比目前国内外普遍采用的方法更简便灵活,准确可靠。这套方法是以岩组图的制作为出发点,但它同样可以用在金属学,结晶学,以及与空间向量统计研究有关的其它领域中,具有比较广泛的用途。
It is a very time-consuming work to make rock pictures generally including scatter diagrams, adding dense lines such as paintings and the necessary transfiguration. At present, although these jobs can be replaced by computers by hand, they are not always convenient. The new method proposed in this paper includes a set of complete mapping methods such as plotting of projection points, transformation and delineation of projection surfaces, which is more simple, flexible, accurate and reliable than the commonly used methods at home and abroad. This method is based on the production of rock pictures, but it can also be used for a wide range of purposes in metallurgy, crystallography, and other fields related to the study of space vector statistics.
