在地质研究工作中,地质工作者为了直观地说明地质现象及其意义,总要对某些具特殊结构、构造的岩石、矿石标本磨成光块或光片进行显微照相或做素描图,附于文字资料中,以增强表达力。绘制素描图需要一定的技巧,虽可有意识地突出结构构造特点,但缺乏真实感;照相法虽然表达真实,但花费时间长,成本高。我们试验用E P650Z复印机,直印标本光面,印制成的结构构造图象,反差适中,层次分明,形像逼真,并能按比例缩放,经济实用,速度快。下面是在复印机上印制的标本光面的结构构造图。
In the geological research work, in order to illustrate the geological phenomenon and its significance intuitively, the geological workers always need to make some photographic pictures or sketches of certain rock and ore specimens with special structures and structures, Attached to the text in order to enhance expression. Draw sketch drawings need some skills, though it may consciously highlight the structural features, but the lack of realism; photographic method although the true expression, but takes a long time and high cost. We experiment with the E P650Z copier, straight printed specimen smooth, printed structure made of images, contrast moderate, structured, realistic image, and can be scaled, economical and practical, fast. The following is the structural drawing of the glossy surface of the specimen printed on the copier.
