Abstract

The volume scattering function is calculated for particle suspensions consisting of two components systematically distributed in a manner consistent with Coulter Counter observations in the Sargasso Sea. The components are assigned refractive indices 1.01-0.01i and 1.15 to represent organic and inorganic particles, respectively. The only models found that reproduce observed scattering functions require a considerable fraction of the suspended particle volume to be organic in nature. This fraction, however, contributes less than 10% to the total scattering function. The model finally chosen indicates that the inorganic particles smaller than 2.5 micro do not occur in large enough concentrations to have a significant effect on the volume scattering function.

摘要

针对由两种成分组成的粒子悬浮液，计算了体积散射函数。这两种成分以与马尾藻海库尔特计数器观测结果一致的方式系统分布。分别为这两种成分赋予折射率1.01 - 0.01i和1.15，以分别代表有机和无机粒子。发现的唯一能重现观测到的散射函数的模型要求相当一部分悬浮粒子体积本质上是有机的。然而，这一部分对总散射函数的贡献小于10%。最终选择的模型表明，小于2.5微米的无机粒子浓度不够高，对体积散射函数没有显著影响。
