摘　　要：微藻光自养生长的细胞密度很大程度上受到光生物反应器中光能传递效率的限制,研究光生物反应器中光能传递规律是提高微藻光能利用效率的基础。分别综述了微藻在光生物反应器中的光衰减和光强分布数学模型,这些模型不但能揭示微藻培养过程中光能的动态变化规律,也为开发高效的光生物反应器和优化培养工艺提供理论依据。The cell densities of photoautotrophic microalgae were limited by the efficiency of light trans- mission in photobioreactors to a great extent. Therefore, the study on light transmission in photobioreactor was the theory foundation for improving the efficiency of light utilization. This work reviews the different mathemati- cal models of light attenuation and distribution in microalgal culture in different, types of photobioreactors. These models can be applied to describe the changes of light intensities in different microalgal cultures, but al- so provide a theoretical support for efficient photobioreactor design and culture condition optimization
