| 摘 要： | 通过对均匀半空间中心回线装置瞬变电磁法核函数的研究，推导了中心回线瞬变电磁法观测二次电位误差对计算全期视电阻率的影响的表达式，发现在晚期微小的二次电位的误差将比早期对视电阻率的计算的影响更大，并介绍了目前对提高早晚期数据采集与处理质量的方法技术。

| Abstract: | The kernel function of the center loop transient electromagnetic method in homogeneous half space is analyzed thoroughly,deduced the expression of the influence secondary potential errors exerts upon calculating alltime apparent resistivity,discovered that the small secondary potential errors will have a greater impact on calculating all-time apparent resistivity in later time than in early time.And the current methods and techniques of improving the quality of data collection and data processing in early time and later time are introduced. |

| Keywords: | Center loop transient electromagnetic method secondary potential the influence of calculating all-time apparent resistivity |
