| 摘 要： | 给出了由电偶源垂直磁场Ｈｚ（ｔ）计算全区（期）视电阻率的数值计算方法；将时间范围扩展到几十秒，以满足大偏移距（ｒ）探测大深度的需要。模拟计算结果显示，全区视电阻率能清晰地反映地电断面的结构，有助于定性定量解释

| Abstract: | The numerical calculation method of apparent resistively in whole area(period)by vertical magnetic field Hz(t) of electric dipole is given,and the time range is expanded to tens seconds to satisfy the need for detecting larger depth by big offset distance( r).The results of analogy computation indicate that the apparent resistivity in whole area can clearly reflect the structure of geological section,contributing to the qualitative and quantitative interpretations. |
