How to separating meiofauna accurately from sediments is an unfathomed problem, because meiofauna has the similar size and density with sediment granules.
由于小型底栖生物的大小、比重等物理特性与沉积物颗粒接近，如何高精度地分离样品成为一个难题。

To separate the liquid and gas phase, the separator makes use of the difference in density between them, and takes advantage of ESP high speed rotating, which used to power a separating device.
液气分离器就是充分利用电泵机组的高转速、气体和液体之间悬殊的密度差异进行液气离心分离。
