摘　　要：微藻的辐射特性参数是进行光生物反应器内光线传输、微藻生长及生物质量预测的基础物性参数。本文实验研究了鱼腥藻的不同浓度下的吸收系数和散射系数,并给出了鱼腥藻的吸收截面和散射截面以及散射反照率辐射特性参数。研究表明:鱼腥藻的吸收系数和散射系数随浓度的增加而增大,吸收截面和散射截面与浓度无关,散射反照率在可见光谱大于0.7。吸收截面在435 nm和676 nm波长下的吸收峰对应于叶绿素a,450 nm和637 nm处的吸收峰相应于叶绿素c,485 nm波长下的吸收峰对应于类胡萝卜素。The radiative properties of microalgae are basic parameters used to analyze light transfer, microalgae growth and to predict the productivity of biomass within photobioreactors. In this paper, the absorption coefficient and scattering coefficient of Anabaena sp. were experimentally studied for different cell concentrations. The radiative properties parameters of absorption cross-section, scattering cross-section and scattering albedo of Anabaena sp. were presented. The results show that the absorption coefficient and scattering coefficient of Anabaena sp. increases with the increase of cell concentration. The absorption cross-section and scattering cross-section are independent on cell concentration, and the scattering albedo is above 0.7 in the visible spectral region. The absorption peaks at 435 nm and 676 nm of absorption cross-section corresponds to Chl a, the absorption peaks at 450 nm and 637 nm corresponds to Chl c, and the absorption peak at 485 nm corresponds to carotenoids.
