It is found surprisingly,that the direction of the largest deff of the crystal is not in the principal plane as usual but along (θ=65.9°,=36.5°) and (θ=66.3°,=143.9°) and further,its value is direction dependent in the different phase regions.

Principal plane: Any plane that contains two principal axes is regarded as a principal strain plane, where AB refers to the maximum principal plane, BD, the minimum principal plane and AD, the intermediate one.

主平面：包含任意两个应变主轴的面称为主应变面。其中：AB面为最大主平面，BD面为最小主应变面，AC为中间中应变面。AD面-代表亚性面，BC-代表张性面

In relation to the feature extracting, the first step is to extract the "simple" surfaces such as planes, natural quadric surfaces and tori. Planes considered as degenerated quadric surfaces, the quadric surface feature extracting should be more important in RE.

而在点云的特征提取中，首先提取的是包括平面、自然二次曲面(包括球面、圆柱面、圆锥面)和圆环面的"简单"曲面，我们认为平面是一种退化了的二次曲面，因此研究二次曲面特征的提取是其中首要的课题。
