| 摘 要： | 从平行场传感器的二维模型的磁场解析入手，在导出解析解的基础上，对电磁层析成像（ＥＭＴ）的物理机制，物场信号的检测方法和ＥＭＴ的检测极限等进行了定量分析和讨论，在一定程度上为研究和解决ＥＭＴ传感子系统的定量设计原则提供了数学基础和理论依据。

| Abstract: | This paper starts with a direct analysis of two dimensional magnetic field of a parallel field sensor model.Based on the analytical results,quantitative analysis was made on the physical mechanism of electromagnetic tomography(EMT),detection method for the object field signal and detectability limits of an object.To a certain extent,a mathematical and theoretical basis is provided for studying and resolving quantitatively design principles for the sensing subsystem. |
