摘　　要：首先介绍了织构测量的极图和反极图法，二者因测算简便，容易辩读，迄今仍大量使用；其次重点介绍了织构的三维取向分析——ＤＦ分析的原理和求算过程，以及Ｆｒｉｅｄｅｌ定律对ＯＤＦ分析结果的影响和人们为求算完整ＯＤＦ而进行的种种尝试及努力，最大熵原理用于ＯＤＦ分析的最大熵法是目前求算完整ＯＤＦ最为切实可行且结果最为理想的方法，使织构定量测量更接近实际。Pole figure and inverse pole figure are introduced firstly, and both of them have been widely used in texture analysis as they are convenient in determining and recognizing. Then, the following are presented in details: the orientation distribution function (ODF), principle and calculation -process. The influence of Friedel Law on the results of ODF analysis, as well as much attempt to get complete ODF are also introduced in the present paper. Maximun Entropy Method applied to ODF analysis is considered to be better way for quantitative texture analysis. Texture quantitative result will be more real if Maximum Entropy Method is introduced to ODF analysis.
