摘要
探讨了在电偶源频率电磁测深中利用磁场比值定义的视电阻率ρzy 的物理意义及与其相位间的频散关系,给出了在频散关系的基础上由视电阻率资料估算相位的方法,并证明所估算的相位与理论模型计算值是一致的.研讨了ρzy 与φzy 联合反演问题, 并研制出具有较好应用效果的实用化软件.
The physical meaning of the apparent resistivity ρ zy which is defined by the ratio between magnetic field's components and its phase in the frequency electromagnetic sounding with the electric dipole sources is discussed and the method of estimating the phase by using the data of the apparent resistivities on the basis of dispersion relation is given.It has been proved that the estimated phase values coincide with those calculated by theoretical models.In addition,the ρ zy -φ zy joint inversion problem is studied and the practical software which has a better effect in the application is developed.
