| 摘 要： | 研究发现,瞬变测深法研究深度除了与采样时间(采样间隔,起始和终止采样时间等)有关外,还与信号源强度、大地电导率、系统噪音水平以及仪器观测精度等因素有关,文中对研究深度与这些量之间的关系作了数学描述。

| Abstract: | The depth of investigation of TEM sounding method has been discussed in this paper. The auther found that the depth of investigation of TEM sounding not only related with the sampling time, but also related with the signal strength,the conductivity of the earth,the noise level and precision of measuring system. The relationship between these aspects and the investigation depth was carried out mathematically. |

| Keywords: | the depth of investigation noise level of measuring system signal strength average conductivity |
