摘 要: 在沈陽土壤腐蝕試驗(yàn)中心站現(xiàn)場原位測試了土壤的理化性質(zhì)和純銅的腐蝕速率變化情況。土壤理化性質(zhì)測試結(jié)果表明，土壤的電導(dǎo)及含鹽量隨地溫的升高而增大，土壤中微生物腐蝕隨著地溫升高而顯著增強(qiáng)，原位測試結(jié)果顯示純銅的腐蝕速率隨著地溫的升高而增大，與實(shí)測質(zhì)量損失值對(duì)比，兩者誤差較小，因此純銅可作為一種原位測試土壤腐蝕性的標(biāo)準(zhǔn)電極材料。

Abstract:In-situ measurement of corrosion rate of copper and soil physico-chemical factors was carried out in Shenyang soil site. The results show that soil conductivity, salt content and bacterial corrosion of soil increase with raising soil temperature，and the corrosion rate of Cu also increase with the soil temperature. The comparison of in-situ mass loss with actual measured value shows that the error between them is very little. Therefore，copper may become a standard measuring electrode for soil corrosion.
Key words: copper; soil corrosion; in-situ measurement
