| 摘 要： | 对大地电磁（ＭＴ）阻抗张量正则分解的基本理论进行了阐述，重建了物理意义明确的参数体系。通过理论推导和等价性讨论，说明新参数与传统的坐标轴旋转法参数之间的对应关系，使这一数据处理方法能够成为用于大地电磁测深的实用技术。

CANONICAL DECOMPOSITION AND PARAMETER RECONSTRUCTION OF MT IMPEDANCE TENSOR |
| |
| Abstract: | he basic theory on the canonical decomposition of MT impedance tensor is discussed in this paper. The complete parameter system is set up, in which each parameter has clear physical meaning. The corresponding problems of new parameters with the parameters of traditional method are solved by the derivation of equations and the discussion on the equivalence between the two methods of coordinate rotation and canonical decomposition of MT impedance tensor. Turning the theory of data analysis into a practical technique, this new method can be used for MT data processing. |
