摘　　要：近代以来,随着计算机领域的兴起,在工程物探当中仪器也越来越智能化、高效化,虚拟仪器的使用也越来越广泛。本文以虚拟仪器技术为基础展开了工程物探电磁模拟实验平台瞬变电磁虚分量研究,通过公式推导出回线源下瞬变电磁法和大回线法的响应,模拟理论情况下随电流幅值变化和线圈匝数变化的阶跃电流的响应曲线并在实验室测试进行结果验证。结果表明所研究开发的瞬变电磁实验装置符合设计要求,具有较大的实际使用价值。In modern times,with the rise in the computer domain,instrumentation in engineering geophysical exploration has increasingly become more intelligent and efficient.The use of virtual instruments has also expanded significantly.This study,grounded in virtual instrument technology,delves into the transient electromagnetic virtual component of the engineering geophysical simulation experiment platform.We derived the responses of the transient electromagnetic method and the large loop method under a loop source through formulas.We then simulated the response curves of step current,considering changes in current amplitude and coil turns,in an ideal scenario.These simulations were subsequently verified through laboratory tests.The results indicate that the developed transient electromagnetic experimental device meets the design criteria,showcasing significant practical applicability.
