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。
A suspension is the discrete system in which many particles of a substance exist in another medium. It is a common form of material existence in nature. Therefore, the determination of the content of suspended matter and its particle size compositional characteristics are of great significance for the study of geology, biology, meteorology and ocean optics and water conservancy projects.
