摘要
测定了三种不同类型土壤的主要理化性质,并根据DIN50929评价标准,对三种土壤腐蚀性进行综合评价。重点研究了含水量对三种土壤电阻率的影响关系,对不同含水量下接地材料的腐蚀数据进行了拟合,确定了腐蚀量与时间的关系曲线。
The physicochemical properties of three kinds of soil were mensurated and the corrosion property of three kinds of soil was evaluated by standard DIN50929. The relationship between the moisture content and soil resistivity was studied. According to the fitting of the corrosion data of different water contents, the relationship between corrosion mass and time was given out.
