摘　　要：采用YPMS-2生物光子测量仪检测栅藻的延迟发光。将测得的结果输入到Origin Pro 9.1软件中,与双曲线函数做最佳线性拟合并分析。栅藻有较强的生物光子辐射能力,其延迟发光的双曲线规律为生物光子辐射的相干性理论提供了证据。双曲函数拟合出来的三个参数(I0、τ、β),携带着不同浓度栅藻和液体培养基的信息,即生物光子辐射对生物系统内部的变化及外界环境的影响有高度的敏感性,为栅藻可作为液体环境的生物指示剂,奠定了一定的理论基础。To detect the delayed luminescence of the scenedesmus by usingthe YPMS- 2 Biophotonmeasuring instrument. The measured results were inputted to the Origin Pro 9. 1 software,the best linear fit was done with the hyperbolic function. The scenedesmus had strong ability of biophotonemission,the hyperbolic law of delayed luminescence provided some evidences for the coherence theory of biophotonemission. The three parameters（ I0,τ,β） of the hyperbolic function carry the information about the different concentrations of Scenedesmus and liquid media. In other words,biophotonemission has high sensitivity to the internal changes of biological systems and the impact of the external environment,which lay a certain theoretical basis for the scenedesmus being used as biological indicators of liquid environment.
