【Abstract】 In this paper,surface characterization of steel corrosion has been researched by fractal theory and it has been proved by test that it has the fractal character. The power spectrum method is chose to calculate the fractal dimension,so it will help to solve the difficult of safety assessment for In-service steel structure.更多还原
