摘　　要：人工源电磁法是深部资源探查的重要手段,其核心在于通过创新技术提升探测深度和精度。电磁法的探测模式由远场转向近场是电磁法的重要变革,研究近源电磁探测方法是近年来的国际前沿。基于最新发展的广域电磁法和多通道瞬变电磁法,作者团队提出短偏移距瞬变电磁法(SOTEM)。该方法的特点在于收发距离小,短偏移情况下信号更强、带宽更宽,更有利于实现大深度和高精度的探测。本专栏收集了8篇关于短偏移距瞬变电磁探测方法、技术、软件和应用的文章,这些研究成果将有力支持更深层次的精细探测需求。The artificial source electromagnetic method is an important technique for deep resource exploration.The key challenge is to improve the depth and precision of detection through innovative technology.The detection mode of electromagnetic methods is evolving from far-field to near-field,and the study of near-source electromagnetic methods has become an international research frontier in recent years.Building on the recent advancements in wide-field electromagnetic methods and multi-channel transient electromagnetic methods,the short-offset transient electromagnetic method(SOTEM)has been further developed and proposed.The distinguishing features of SOTEM are its stronger signals and wider bandwidth,which are advantageous for achieving the detection requirements of greater depth and higher precision.This special issue presents eight articles covering the methods,techniques,software,and applications of SOTEM,providing strong support for the growing need for high-resolution subsurface detection.
