中文摘要：
采用试件自然埋藏及土壤环境因素原位连续测试方法，研究了在鹰潭试验站土壤中，线缆金属材料Pb、Al、Cu埋藏1a的腐蚀率变化规律。结果表明，在土壤环境因素变化差异较大的春夏季节交替时，腐蚀率最大。在埋藏的3种金属中，Pb腐蚀较严重。
英文摘要：
By means of naturally burying and testing metal specimen seasonally, testing soil environment factors such as temperature, humidity, salinity and conductance every half a month, the rule of cable metal materials′ （ Pb, A1 and Cu） corrosion rate varying with the seasonal changing of soil environment factors within one year in Yingtan was studied. The testing result indicated that there was relativity between Pb, A1 and Cu corrosion rate during different burying periods and the varying of soil environment. The maximum corrosion rate occurred when spring and summer alternated （from April to July） when the soil environment factors altered severely. The corro- sion rate of Pb which was the highest among the three kind of metals was 11 times of that of A1 and 3 times of that of Cu as Pb was affected by pH of acid soil, dissolvable salinity （NO3^-,CO3^2- and HCO3^-） and soil animalcule.
