摘　　要：人机交互航磁异常切线法系统模拟手工切线法计算磁性体顶面埋深的流程,充分发挥解释人员的经验和智慧,同时利用计算机善于计算、查表以及图形处理的强大能力,实现了单测线和多测线显示、缩放以及平移,局部异常特征线和特征点自动绘制、交互修改、磁性体形态参数、深度、宽度以及磁化强度的自动查表计算,特征线和特征点、计算结果显示、保存等实用功能,极大地提高了航磁异常深度计算的可视化程度,减轻了解释人员的劳动强度,提高了工作效率,同时为个别异常的精细解释提供了不同方法。该系统采用面向对象设计方法,以VC++作为开发工具,可运行于各类W in32平台之上。The manual computer interaction aeromagnetic tangent method system is designed according to the flowchart of the manual tangent method. It combines manual experience and wisdom with strong computer power in calculating, consulting tables and processing graphs. It has many useful functions. Single profiles or multiple profiles can be displayed, zoomed and moved; characteristic lines and points can be protracted automatically and amended by manual computer interaction ; depth, width and magnetization of magnetic body can be calculated automatically; results can be saved and displayed; visualization and work efficiency are improved considerably. Therefore, a great deal of work can be reduced. It also provides different means for effective interpretation of aeromagnetic anomaly. This system is developed with the VC ＋ ＋ development tool and is object-oriented. It can be applied on the win32 system.
