| 摘 要： | 介绍了阻抗张量分解技术及其在阳高～容城剖面的大地电磁资料解释中的应用。在某些测点局部电流畸变的影响较严重，用张量分解技术对资料分析后表明，沿剖面的区域异常总体上具二维性质，分解技术处理后的视电阻率和相位资料与地质构造有较好的对应性。事实表明，阻抗张量分解技术是对大地电磁资料进行分析解释的有力工具

| Abstract: | Decomposion of the magnetotelluric impedance tensor is used in evaluation of MT data observed at sites along profile from Yanggao in Shanxi province to Rongcheng in Hebei province.The impedance tensor at some sites is influenced by strong local telluric distortion.Analysis on all data along the profile suggests that regional anomaly is two-dimensionality in general.The pseudosection of apparent resistivity and impendance phase for regional anomaly can be compared with tectonics. |
