Dynamic simulation of multi-stage countercurrent is an important subject in the field of Chemical Dynamics. 多级逆流过程的动态模拟,是化工动态学领域中的一个重要课题。
Heap leaching is a countercurrent process where the solid is in a stationary heap and the solvent percolates through the solid. 堆滩浸出是一种逆流过程,其中固体是一个固定堆,溶剂从其间穿流而过。
