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。

The invention discloses an electrochemical method for preparing a hydroxylapatite particle thin coating on the surface of a metal implant, which comprises the following steps: electrolyte is put into a container equipped with a constant temperature heating system and heated to be 30 DEG C to 95 DEG C, and then the temperature is kept; platinum is taken as the anode and evenly distributed around the container, and the metal implant is taken as the cathode, put in the middle of the container and totally soaked in the electrolyte; DC voltage of 2V to 4V is added between the anode and the cathode, the surface of the metal implant has cathode reduction reaction, the pH value is increased and the supersaturation degree of the hydroxylapatite is also increased, so as to crystalize on the surface of titanium; after 0.5h to 5h of deposition, a layer of hydroxylapatite particle thin coating which can be excellently adhered to the matrix metal is formed on the surface of the implant.

本发明公开了一种在金属植入体表面制备羟基磷灰石颗粒薄涂层的电化学方法，在装备了恒温加热系统的容器中装入电解液，并将电解液加热到30～95℃恒温；将铂作为阳极均匀分布在容器四周，金属植入体作为阴极置于容器中间，完全浸没在电解液中，两极之间加直流电压2～4V，金属植入体表面发生阴极还原反应，pH值升高，羟基磷灰石过饱和度增加，从而结晶在钛金属表面；经过0.5～5小时沉积后，在植入体表面即可形成一层与基体金属结合优良的、薄的羟基磷灰石颗粒薄涂层。
