针对碳钢材料 8年实海试验的腐蚀结果 ,采用数学模拟的方法进行了分析 ,提出了环境腐蚀系数的概念和包含环境腐蚀系数的碳钢腐蚀深度方程。青岛、厦门、榆林等三个腐蚀试验站的全浸区腐蚀数据与该工程的计算结果非常吻合 The corrosion results of 8-year solid-sea test of carbon steel were analyzed by mathematical simulation. The concept of environmental corrosion coefficient and the corrosion depth equation of carbon steel containing environmental corrosion coefficient were proposed. The corrosion data of all immersion zones of three corrosion test stations in Qingdao, Xiamen and Yulin are in good agreement with the calculation results of this project
