【摘要】 <正> 悬浮体是一种物质的许多颗粒存在于另一种介质中构成的离散体系。它是自然界中物质存在的一种常见形态。因而测定悬浮物质的含量及其粒度组成特征,对于地质、生物、气象和海洋光学以及水利工程的研究是很有意义的。更多还原

【Abstract】 The formula of the optical density of the suspended particles is obtained by means of the calculation of the single scattering. A factor (?), which is the ratio of the effective cross-section for scattering of a particle to its geometrical cross-section, and a parameter R, which may be called the average optical radius of the suspended particles, are shown to be necessary for determining the concentration of the suspended particles from its optical density measured.更多还原
