| 摘 要： | 由于常规的张量旋转分析方法的局限性，在处理三维阻抗问题时不能得到令人满意的结果.最新发展的三维阻抗张量的正则分解方法由于不需约束条件，可以自然的从三维阻抗张量中提取完整的参数体系，因而具有很好的应用前景.本文对正则分解的方法从理论上进行了分析和证明，对原有参数计算公式做适当的修改，将正则分解与坐标旋转结合起来，分析二者之间的联系与区别，并探讨参数的地质含义. |

| Abstract: | Because of the limitations of the ordinary analysis methods for magnetotelluric impedance tensor, we can’t get satisfying results. The canonical decomposition may be the best method to deal with 3-D dimensional MT impedance, and has more estimated appliance, because a set of integrated parameters can be picked-up unartifically by means of this method. In this paper, we analyze and test the method as canonical decomposition, make a suitable modification on parameter formula, make an analysis on the relationship and difference between canonical decomposition and coordinate circumrotation. The geological meaning of the parameter are discussed. |
