A seven-node difference scheme of the diffusion equation was proposed to study the behaviors of transient electromagnetic field in complicated 3-D geoelectric body. Models of roadway and anomaly body were set up for simulating the transient field excited by a vertical magnetic dipole source. The result of numerical simulation shows that the presence of low resistive conductor leads to noticeable distortion of isolines for the "smoke ring" field, whereas the distortion is not so obvious where the roadway and the poor conductor are located.

The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.

结果表明：随着变形量的增大和Fe-Cr纤维的细化，纤维的饱和磁矩基本恒定(约140 A·m2/kg)，而剩磁和矫顽力则逐渐增加； Fe-Cr纤维在无水乙醇和空气中储存一年以上，磁性基本保持不变； Fe-Cr纤维在空气中经300 ℃以上加热1 h后，逐渐由铁磁性的α-固溶体转变为顺磁性的2O3，饱和磁化强度显著下降；且随着变形量的增大，较细Fe-Cr纤维的热稳定性较差。
