提出了描述正交各向异性材料的取向程度的二阶对称张量，并证明了它能准确地反映实验数据的模式。将该张量描述微观结构各向异性的方法与目前公认的方法进行了比较，发现在实验研究中更有用和准确。给出了一种在任意三个相互垂直的平面上测量材料各向异性张量的方法，并讨论了该方法对正交异性材料的基本限制。本文给出了五种不同人骨的松质骨的各向异性张量。
A second rank symmetric tensor which describes the degree of orientation in orthotropic materials is presented and shown to reflect accurately patterns of experimental data. The use of this tensor to describe microstructural anisotropy is compared to currently accepted methods and is found to be more useful and accurate in experimental studies. A method for determining the anisotropy tensor in a material is given, based on measurements on any three mutually perpendicular planes, and the fundamental restriction of this method to orthotropic materials is discussed. Experimentally determined anisotropy tensors in five specimens of cancellous bone from five different human bones are given.
