中文摘要：
为了解决由于织构漫散度给织构分析带来的估算误差，以达到对材料织构进行更为精确的分析，采用从极图求算ODF（orientation distribution function）中的“二步法”作为基本原理，选择以1^o为最小间隔单位划分欧拉空间，对欧拉空间所有取向点的取向密度进行了求算，并建立了相应的分析系统．利用该分析系统对鞍钢生产的IF钢冷轧和退火样品进行了计算，并与已成熟的以欧拉角5^o为最小间隔单位的ODF求算系统对比．结果表明：以欧拉角1^o为最小单位的ODF取向密度分析系统比以欧拉角5^o为最小单位的ODF取向密度分析能更确切地表示织构的分布情况．
英文摘要：
The two-step method of calculating ODF （orientation distribution function） from pole figure as the basic principle was used to precisely analyze cubic system material texture. The Euler space was divided by 1^o minimum unit. All of the divided spot＇s orientation density were calculated all over the orientation space. In addition, the corresponding analysis system was established. By means of the analysis system the textures of coldrolled and annealed IF steel specimens produced by Angang were calculated and were compared those with the sophisticated ODF calculation system by the Euler angle 5^o minimum unit. The results show that the analysis system by the Euler angle 1^o minimum unit can more exactly express the texture distribution than by the 5^o minimum unit.
