摘要
河源地电台开展的深孔短极距试验观测，其电极深度达６５ｍ左右，μ值（Ｈ／Ｌ）达２．４。这种近似全空间的地电阻率观测方法，经试验证明在降低地电台站地表环境干扰因素的影响，提高观测精度，降低线路造价和维护费用等诸方面的效果是明显的．
The resistivity observation test with deep-hole electrodes and short pole distance was carried out at Heyuan geoelectrical observatory in July 1992. The electrodes depth is about 65m, its μ-value (H/L) is about 2.4. The conclusion obtained from the test is: The whole space method is efficacious in reducing the interference effect, increasing the observation accuracy, and lowering the whole cost.
