摘要
大地电磁测深解释中的一项重要工作是正确识别ＴＥ，ＴＭ 极化视电阻率曲线。首先分析了ＴＥ，ＴＭ曲线的畸变规律， 认识了ＴＥ， ＴＭ 曲线畸变差异。在此基础上， 提出了用相关分析法识别两类曲线。该方法依据不同测点ＴＥ曲线的强相关性来识别ＴＥ，ＴＭ 视电阻率曲线。实测资料处理表明，用该方法进行ＴＥ，ＴＭ 曲线的识别是实用、有效的。
An important task for magnetotelluric data interpretation is to identify the apparent polarized resistivity curves of TE and TM mode The distortion of TE and TM and differences of distortion of TE and TM curves are recognized and a correlation analysis,namely method of stronger correlation of apparent TE resistivity, is proposed to distinguish two kinds of curves Results of data processing indicate that this method is practical and effective in identifying the TE and TM polarized mode
