Firstly, we normalized the basic voxel by constructing its minimum oriented bounding box. Secondly, we constructed its D2 shape distribution curve, and computed the values of EMD(earth mover's distance) compared with the corresponding curves of the normal cone and cylinder respectively, and the corresponding top diameters. Finally, we compared the top diameters and obtained the parameters by the bounding box.

经方差分析可以看出,利用射线直径、管胞直径和射线管胞比可以在总体上区分各标本,但对个别样本不适用;射线高度这一性状在各标本间差别很小,不能区分;结果认为:标本2和标本6的性状最相近,为相同的种类;标本1、4、7可能为同一属;对方差和CSDM曲线的综合分析认为,标本1、3、6的生长年限存在一定的区别,可能导致在方差分析上出现些许误差。

The results show that the radiative properties of randomly distributed soot aggregates for a given fractal dimension are complex functions of the monomer diameters, the number of monomers in the aggregates,and the refractive index; For a small value of the monomer diameters, the absorption cross section of soot aggregates tends to be relatively constant when the fractal dimension is small but increases rapidly when the fractal dimension exceeds two. However, a monotonical reduction in light absorption with the increase of the fractal dimension is observed for soot aggregates with sufficiently large monomer diameters, number of monomers,and refractive index. The scattering cross section , extinction cross section and single-scattering albedo increase monotonically with the increase of the fractal dimension. Overall, the results for soot aggregates differ profoundly from those calculated for the equivalent spherical particles, and the discrepancies between them will change small with the increase of the fractal dimension.

研究表明,在给定分形维数的情况下,烟尘団簇粒子的辐射特性取决于原始微粒粒径、数量及复折射率;原始微粒较小的団簇粒子,当分形维数较小时,吸收截面变化不明显,但当分形维数大于二时,吸收截面骤然增大,然而,对于具有比较大的原始微粒粒径、数量及复折射率的烟尘団簇粒子,吸收截面随着分形维数的增大而单调递减;随着分形维数的增大,団簇粒子的散射截面、消光截面及单次散射反照率均单调递增;从整体上来讲,団簇粒子的辐射特性与等效球形粒子的辐射特性存在着比较大的差别,并且这种差别随着分形维数的增大而减小。
