Results The total effective rates of treatment group and control group were 82.9% and 63.3% respectively, with a significant difference between them (P.05); the hydroperitoneum extinction in treatment group is earlier than that in control group (P.05); the levels of serum ALT, T-BIL Alb and A/G had significant differences between the two groups.

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 results show that Cd2+ for Pistia stratiotes and Myriophyllum spicatum L root-like effects of microbial flora with the microorganism or physiological groups, training time and Cd2+ concentration varies; Micro-organisms under Cd2+ stress would have two distinct effects: First, the growth of micro-organisms are not suited to reduce the number or extinction; Second, the growth of micro-organisms adapt to an increase in the number or the accumulation.

结果表明，Cd2+对大薸和穗状狐尾藻根系微生物的影响随微生物区系或生理类群、培养时间和 Cd2+浓度的不同而不同；受重金属镉胁迫后微生物会产生两个明显的效应：一是不适应生长的微生物数量会减少或灭绝；二是适应生长的微生物数量会增加或积累，在低浓度下，重金属对微生物数量一般有刺激作用，而在高浓度下一般为抑制作用，也有表现出刺激作用。
