Since there were many factors which influenced the results of the continuous casting of electromagnetic crystallizer, using the method of the real object test could cost a lot of experimental expense and lengthen the experimental period.

但有很多因素影响铝钪中间合金的电磁结晶器连铸操作，若采用实物试验的方法，会造成大量试验经费的浪费和实验周期的延长。

This study consists of three parts. Firstly the equivalently accelerative corrosive environment is determined through the analysis of statistic data of corrosion environment. Secondly the fatigue test is carried out under the constant amplitude cyclic loading for the specimens which are exposed in the corrosive environment for equivalent calendar time of zero year, 3 years, 8 years and 13 years. Four S-N curves with different corrosive time are obtained based on the fatigue experiment. Finally the regression method of S-N curves for experimental data is researched and a weighted least square fit is put forward in which the weigh of a group of test data is inversely proportional to the length of the confidence interval.
