| 摘 要： | 利用时域垂直磁场求取全区视电阻率.任意形状回线的垂直磁场可以看成是多个水平电偶极子的垂直磁场累加而成;因此,不论回线是何形状,只要将其分解为水平电偶极子,就可利用水平电偶极子的垂直磁场求取任意形状回线的全区视电阻率.

| Abstract: | All-time apparent resistivity is attained by vertical-magnetic field.The vertical-magnetic field of arbitrary shape loop can be considered as the sum of the vertical-magnetic field of many horizontal electric dipoles;therefore,no matter what the shape of the loop,as long as the loop was divided into electric dipoles,we can use the vertical-magnetic field of horizontal electric dipole to attain the all-time apparent resistivity of arbitrary shape loop. |

| Keywords: | layered medium arbitrary shape loop source all-time apparent resistivity |
