| 摘 要： | 基于Mie散射理论,利用一次聚生角毛藻赤潮生消过程的水体吸收光谱数据,反演了藻细胞的折射率虚部,开展了细胞平均吸收效率因子(Qa)、后向散射效率因子(Qbb)和散射相函数的光谱模拟与分析。研究发现:(1)均匀球模型(Mie理论)能较好地重现聚生角毛藻的吸收光谱特征,Qa平均相对误差在11%以内。(2)Qbb受吸收影响,这一方面体现于Qbb在400～700nm波段的光谱变化,即吸收极大值的波长处Qbb取极小值;也体现在整个赤潮生消过程中,赤潮爆发前Qbb大,赤潮爆发后Qbb变小。(3)总散射与粒径参数(表征粒径相对于波长的大小)成正比,受吸收的影响小;总散射与角度散射强度反比于波长。 |

| Abstract: | The present paper utilizes the absorption data of red tide water measured during the growing and dying course to retrieve imaginary part of the index of refraction based on Mie theory,carries out the simulation and analysis of average absorption efficiency factors,average backscattering efficiency factors and scattering phase function.The analysis of the simulation shows that Mie theory can be used to reproduce the absorption property of Chaetoceros socialis with an average error of 11%;the average backscat... |
