参考美国标准ASTM E1268-2001（2016）制定了一种钢中带状组织的定量评定方法，从网格测量线的创建、放大倍数及视场数量对测量结果的影响、定量评定方法与国标评级结果的对应关系等方面进行了分析。结果表明：创建网格测量线时，自动创建比手动创建精度更高；低倍（50~200倍）下采集视场图进行定量评级的精度值均满足要求；采集5个视场基本能满足统计和计算需求，当相对精度高于30%时，可增加视场数量以提升测量结果的精确度；在定量评定方法中，取向性程度和各向异性指数随带状组织级别的增加而增大，而在国标采用的图谱比较法中，没有明确的取向性程度和各向异性指数与带状组织级别对应。

Referring to the American standard ASTM E1268-2001(2006), a quantitative evaluation method for banded structure in steel was developed. The establishment of grid measurement line, the influence of magnification factor and the number of field of view on measurement results, and the corresponding relationship between quantitative evaluation method and national standard rating results were analyzed. The results show that when creating grid measuring lines, the accuracy by automatic creation was higher than that by manual creation. The accuracy of quantitative rating of field of view maps collected at low magnification (50-200×) met the requirements. The acquisition of five field of view could basically meet the needs of statistics and calculation. When the relative accuracy value was higher than 30%, the number of field of view could be increased to improve the accuracy of measurement results. In quantitative evaluation method, the values of orientation degree and anisotropy index increased with the increase of banded structure grade. However, there was no clear correspondence between the values of orientation degree and anisotropy index and banded structure grade in atlas comparison method in national standard.
