摘　　要：验证和比较钢铁中氮量测定的两种国际标准方法ISO10 70 2和ISO10 72 0。试验结果表明 ,在ISO10 72 0方法中 ,可以用锡囊盛放标准溶液 ,而且锡囊的使用效果要比镍囊的好。对比两种方法的测定结果 ,当氮含量大于 0 0 10 0 %时 ,测定结果没有明显偏差。小于 0 0 10 0 %时 ,还需要进一步实验才能得出结果。The two international standard methods ISO10702 and ISO 10720 for the determination of nitrogen content in steel and iron were tested and compared The results showed that a tin capsule filled with the standard solution was allowable to be used, the effect of this capsule was better than that of nickel capsule. Compared with these two methods,there was no obvious deviation among their analysis results when the nitrogen contents were larger than 0 0100%,but when the nitrogen contents were lower than 0 0100%,the more experiments should be further done to draw conclusions
