摘　　要：根据光子能量的计算方法,计算分析了海洋中生物体的发光能力,结果表明在低浓度分布时发光生物体的辐照度是完全可测的;考虑随机介质中光传输的多次散射,利用蒙特卡罗方法建立了研究生物光传输特性的理论模型和算法,仿真计算结果表明:生物光在均匀介质中的传输符合朗伯特-比尔衰减定律,随着距离的增加传输能量按指数衰减;通过对给定模型参数的计算表明472nm的生物光在一类海水中传输120m后仍然能够被高灵敏的探测器探测到;波长对生物光水中传输的整体特性影响不大,但随着波长的增加衰减系数增大;生物的粒径大小对衰减系数的影响较大,随着粒径的增大光传输的衰减系数会有较明显的增大。The luminescent capability of organisms in sea water was calculated and analyzed based on the calculation method of photonic energy combined with the actual concentration and bioluminescent intensity of organisms in the ocean The results showed that the radiometric illumination with low concentration of bioluminescent organisms was detectable. The theory models studying the transmission characteristics of bioluminescence were developed using Monte-Carlo method and the Monte-Carlo simulation algorithm calculating multi-scattering of oceanic bioluminescence was established considering of the multi-scattering effects of transmission in random medium. The transmission signals of bioluminescence were simulated with above algorithm. The results showed that the transmission of bioluminescence in the sea water was met with the Lambert- Beer law, with development of distance the energy was reduced by index. According to the simulation, the bioluminescence with 472nm would be detected by high sensitive detection when it transmitted 120 meters. And the transmission didn＇t depend on the bioluminescence wavelength, the attenuation coefficient would be increased with the wavelength. The attenuation coefficient seriously depended on the bioluminescence organism size, with the development of size the attenuation of biolumi-nescence transmission would be obviously increased.
