在辽宁省乡村进行Ａ３钢的两年大气暴露试验，绘制了辽宁省乡村气氛中Ａ３钢的大气腐蚀图，并讨论了大气环境因素对Ａ３钢腐蚀的影响规律，对Ａ３钢的腐蚀速率与大气环境因素进行了统计回归分析。
Atmospheric corrosion test of A3 steel in rural atmosphere of Liaoning Province was conducted in two-year atmospheric exposure test of A3 steel in the villages of Liaoning Province. The influence of atmospheric environmental factors on the corrosion of A3 steel was discussed. The corrosion rate of A3 steel and the atmosphere Environmental factors were analyzed by statistical regression.
