关于点、线、面的定向、夹角关系和运动轨迹的分析,常用赤平投影图解比较方便、简明和醒目,而用传统的数学工具来计算,则相对繁琐和麻烦。但是,随着电算技术的蓬勃发展,如今用数学式计算来代替部分赤平投影的功能,在某些方面反而显得又快又准。下面着重介绍赤平投影在构造地质中应用的几个主要问题,先推导成数学式表示,并用带有
About point, line, surface orientation, angle and motion trajectory analysis, commonly used stereotype projection diagram more convenient, concise and eye-catching, but with the traditional mathematical tools to calculate, it is relatively complicated and troublesome. However, with the rapid development of computing technology, the function of replacing part of the stereoproject with mathematical calculation now appears to be quick and accurate in some aspects. The following focuses on the use of stereoproject in tectonic geology in several major problems, first derived into a mathematical expression, and with
