| 摘 要： | 通过对乾陵地震台部分地磁记录图纸的数字化识别，将Z和H分量的识别结果、原始量图值、识别前的人工量图值三者之间进行了对比分析，发现数字化识别结果与人工量图结果的平均误差小于0．6mm，据此认为，数字化识别结果基本可满足地磁历史数据的分析需要。

| Abstract: | Some geomagnetic charts recorded by Qianling seismic station were digitalized, and the results of Z and H components, the original data and the manual measured data in 2009 were compared and analyzed. And the results show that the mean error between them is less than O. 6mm, so the digital records can be satisfied to analyze the geomagnetic data. |
