Unlike sphere inclusion, every ellipsoid inclusion is anisotropic, but compound-inclusion composite material with random distribution of coated-ellipse inclusion can be considered as isotropic. The paper introduces the Fast Fourier transformation method (FFT) and equivalent inclusion approach to calculate the effective conductivity of the transverse isotropic unidirectional coated-fiber composite with coated-ellipse inclusion. In the equivalent inclusion approximation, the two-phase of coated-ellipse inclusions are substituted by the equivalent homogeneous one of the same size and corresponding mechanical properties, from here we can build a simple approximation formula (EI) to determine effective conductivity of three-phase composites. Beside that, the FFT simulation can be combined with the equivalent inclusion approach to obtain the results FFT-EI.

与球体夹杂不同的是，每一个椭球夹杂都是各向异性的，但具有涂层椭圆夹杂随机分布的复合夹杂复合材料可视为各向同性。介绍了快速傅里叶变换法(FFT)和等效夹杂法计算具有涂层椭圆夹杂物的横向各向同性单向涂层纤维复合材料的有效电导率。在等效夹杂物近似中，涂层椭圆夹杂物的两相被具有相同尺寸和相应力学性能的等效均匀夹杂物代替，由此我们可以建立一个简单的近似公式（EI）来确定三相的有效电导率。相复合材料。除此之外，
