求翻译：一般在地表下0.15～0.5m处，是处于土壤干湿交界的地方，接地导体易受腐蚀，因此规定埋深不应小于0.6m，并规定了接地网的引出线在通过地表下0.6m引至地面外的一段需作防腐处理，以延长使用寿命是什么意思？

Generally at 0.15 ~ 0.5m below the surface, is in the border areas of wet and dry soil, ground conductors susceptible to corrosion, and hence a depth of not less than 0.6m, and provides grounding through the surface under the Lead 0.6m lead to the ground outside the period required to be treated wit

General in subsurface 0.15 to 0.5 m, and it is at the junction where wet and dry soils, and earthing conductor susceptible to corrosion and therefore provides should not be less than 0.6 m buried deep under the ground, and the lead in adopting web 0.6 m below the surface to surface, corrosion of req

Under the surface 0.15~0.5m place, is generally is in the soil to do the wet border the place, the earth conductor easy to receive corrodes, therefore the stipulation burying depth should not be smaller than 0.6m, and had stipulated the counterpoise lead-out wire in 0.6m directs through the surface

Beneath the surface at the 0.15~0.5m in General, is at the junction of soil dry-wet areas, grounding conductor is vulnerable to corrosion, provides depth should not be less than 0.6m, and provided the PIN through the subsurface for grounding grid 0.6m led to the ground outside a section should be tr
