摘要
按节理的极射赤平投影原理投影节理。求出节理的百分比值,选出特征百分比点。再据节理百分比值计算出基圆圆周上的百分比值为整值的百分比点,与特征百分比点一起形成点信息文件。并以此方法编写BASIC程序,处理节理的实测产状得到随机文件(点信息文件)。再运用已有的三角网法绘制等值线的程序处理该随机文件,在“APPLE—Ⅱ”微型计算机上实现了自动绘制节理等密图。
Project joints according to the principle of stereographic polar projection, calculate the percentages of joints and select the characteristic point of percentage, then calculate the percentage ratio on the circumference of the basic circle as the percentage point of integer value according to the joint percentage ratio, to form point information files with the characteristic point. A BASIC program is also compiled with the method to deal with the measured occurences of the joints for a random file (point information file) The given trangle net method drawing contour is then used to process the random file, realizing automatic mapping of joint cou-tour diagram with APPLE-Ⅱ microcomputor.
