我们提出了一个三维模型的地震各向异性和纹理的铁晶体的内核。各向异性的形式在略小于内核半径的一半处突然改变。外层由单相铁晶体组成，这些铁晶体沿地球的自旋轴沿着具有不同程度的优先排列。内部部分可以由不同相的结晶铁组成，或者具有不同的排列模式。
We present a three-dimensional model of the seismic anisotropy and texturing of iron crystals in the inner core. The form of the anisotropy changes suddenly at slightly less than half of the inner core radius. The outer part is composed of iron crystals of a single phase with different degrees of preferred alignment along the spin axis of the Earth. The inner part may be composed of a different phase of crystalline iron or have a different pattern of alignment.
