摘　　要：本文在分析烧结NdFeB取向度的各种计算方法的基础上 ,提出一种新的计算方法。采用这种方法 ,仅利用烧结体垂直于外加磁场方向截面的X射线衍射谱 ,通过简单的计算就能很容易的计算出磁体的取向度。The methods evaluating the alignment degree of the sintered NdFeB permanent magnets have been reviewed and a new quantitative evaluation method has been proposed in this article.In this new method,the alignment degree can be easily achieved by simple calculation through the X\|ray diffraction spectrum crossing the plane normal to the applied field direction.
