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。

However, they have their respective shortcomings in mosquitocidal spectrum, persisting and resist-mosquito management. In this research, the mosquitocidal toxin genes cry4Ba and cry11Aa from Bacillus thuringiensis and btx gene from Bacillus sphaericus were co-expressed.cry4Aa,cry4Ba and cry11Aa genes were also co-expressed with btx gene seperatedly and in combination.The constructed recombinants had a high toxicity against susceptible and resistant mosquito.

本研究将苏云金杆菌以色列亚种的杀蚊毒素基因cry4Ba和cry11Aa与球形芽胞杆菌的二元毒素基因btx两种杀蚊菌的杀蚊毒素基因进行了重组，将Bti杀蚊毒素基因cry4Aa， cry4Ba， cry11Aa及Bs的杀蚊毒素基因btx单独或组合表达，所得工程菌株对敏感和抗性库蚊的毒力均有提高，不仅提高了杀蚊毒力，扩大了杀蚊谱，而且部分克服了蚊幼虫对Bs的抗性。
