摘要：
电磁感应（EMI）技术在地球物理勘探中被广泛使用。其成功主要归因于数据采集简便快速，但数据反演的有效性在很大程度上受到感知数据质量的影响，而数据质量取决于设备配置是否适合调查现场的物理特征。正向建模是优化这一方面并设计成功勘探活动的必要工具。本文介绍了一个用于正向EMI建模的新软件工具。它扩展并补充了一个现有的用于EMI数据反演的开源软件包，并包含一个交互式图形用户界面。通过理论介绍说明其用法，并通过一个模拟案例研究进行演示。简要讨论了非线性数据反演问题，并通过一个新的正则化最小范数算法扩展了该软件包的反演模块。
英文摘要：
Electromagnetic induction (EMI) techniques are widely used in geophysical surveying. Their success is mainly due to their easy and fast data acquisition, but the effectiveness of data inversion is strongly influenced by the quality of sensed data, resulting from suiting the device configuration to the physical features of the survey site. Forward modelling is an essential tool to optimize this aspect and design a successful surveying campaign. In this paper, a new software tool for forward EMI modelling is introduced. It extends and complements an existing open-source package for EMI data inversion, and includes an interactive graphical user interface. Its use is explained by a theoretical introduction and demonstrated through a simulated case study. The nonlinear data inversion issue is briefly discussed and the inversion module of the package is extended by a new regularized minimal-norm algorithm.
