中文摘要：

钢结构在工程中应用非常广泛，因此对钢材进行腐蚀试验，了解钢材腐蚀机理及耐腐蚀性能，对钢材防护和工程应用具有重要意义。该文对典型钢（碳钢Q235）／试件，分别在大气和土壤环境中，时间为3个月，采用4种加速腐蚀方案进行试验分析。结果表明，土壤酸（盐）和大气酸（盐）的锈蚀率均与锈蚀时间呈线性关系；土壤中的锈蚀率明显低于大气中的锈蚀率。大气盐试验具有较好的加速性和拟合性。

英文摘要：

It is of great significance for protection and application to make corrosion tests of steel. Here, the accelerated corrosion tests are conducted for a typical steel （carbon steel Q235） in atmosphere and soil environment, and the relationship between corrosion rate and time is established. Compared with natural corrosion steel, the test of salt spray simulation in atmosphere is testified to have good acceleration and fitness.
