The relation coefficient between regression equation and oxidation curve is over 0.9 and the rules of oxidation - temperature and oxidation - time are parabolas.
由计算得到的氧化回归方程与氧化曲线的相关系数可达到0.9以上，高温氧化烧损量与温度和时间均呈抛物线规律。
After the air excess coefficient is greater than 1.1, the oxidation rate of the electrode is increased more quickly; when the coefficient is less than 1.1, the oxidation rate is increased slowly.
当空气过剩系数大于1.1以后，电极的氧化速率增加较大，在小于1的情况下，电极试样的氧化速率较小。
