摘　　要：随着高温超导技术的应用及完善,在TEM测量中直接观测瞬变磁场信号已成为现实,而瞬变磁场数据反演解释方法成为当前急需解决的问题。在借鉴感应电动势资料反演解释方法的基础上,全面阐述了基于瞬变磁场的视电阻率定义,研究了TEM瞬变磁场拟二维反演技术,并从理论模型及实测资料两个方面验证了方法技术的实用性,为促进高温超导TEM的发展提供了方法技术支撑。Theory and practice show that the observation of the transient magnetic field in the TEM has more advantages than that of the induced EMF. With the application and improvement of the high-temperature superconducting technology, the direct observation of transient magnetic field signal has become a reality in the TEM. However, the retrieve interpretation method for transient magnetic field data has become an urgent problem. In this paper, drawing on the interpretation method of the induced EMF, the authors made an overall explanation of the definition of apparent resistivity based on a study of the transient magnetic field and probed into the TEM transient magnetic field for PSEUDO-2D inverse technology. From the theoretical model and the measured data, the authors have verified the practicality of the method, which can provide technical support for the development of the high-temperature superconductor TEM method.
