对弥渡台地电场观测电极进行埋深处理,将原来埋深1.5 m电极深埋到5.0 m。改进后,三个测道长、短极距一致性较好,差值减少到个位数,相关性达到高度相关。通过电极埋深处理前后观测数据的对比分析认为：在地电场观测中,若将电极做深埋处理,则可以有效抑制来自地表干扰。

The field observation electrodes of Midu Seismic Station are deeper buried from the original depth 1.5 m to 5.0 m.Short and long polar distances of the three measured length are consistent,and the difference is reduced to single digits.The correlation is good.Comparison and data analysis show： deeply-buried electrodes can effectively suppress interference from the surface in field observations.
