| 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。 |
