本文介绍由作者研究开发的位场局部异常人机联作解释系统中采用的方法原理和实现过程。本解释系统用于由三维有限形体产生的位场局部异常的人机联作解释。文中详细论述研究开发本解释系统解决的３个主要技术关键问题及其实现过程。这些技术关键问题是：１．任意形体重磁异常的计算方法；２．深入开发人机交互功能；３．建立图形编辑及图示系统。此外，本文还介绍本解释系统的实现环境和具备的功能。为全面介绍位场局部异常人机联作解释系统，作者准备在另外文章中叙述关于软件设计的细节和技巧，使用方法和应用效果 This article introduces the method principle and implementation process adopted by the author in the field of local abnormal human-machine interaction interpretation system. This interpretation system is applied to the man-machine cooperative interpretation of the local abnormalities of the field in the field produced by the three-dimensional finite element. The paper discusses in detail the three key technical problems that are solved by the system of research and development and its realization process. The key issues of these technologies are: 1. Calculation method of gravity and magnetic anomaly of arbitrary shape; 2. In-depth development of human-computer interaction; 3. Create graphic editing and graphic system. In addition, this article also describes the realization of the system environment and have the functions. In order to fully introduce the local anomalous human-computer interaction interpretation system in site, the author intends to describe the details and techniques, the using methods and the application effects in software design in other articles
