presedimentation

The Pt-Fe/C and Pt/C catalysts were prepared with predeposited method.

用预沉淀法制备了炭载Pt-Fe(Pt-Fe/C)和炭载Pt(Pt/C)催化剂。

By means of model experiments of sediment deposition and wash , the characteristics of suspended sediment movement under the action of gravity and turbulent diffusion are studied in this paper, and some problems concerning sediment deposition and wash in the prototype lateral canal are solved.

通过模拟斗槽预沉池中泥沙冲淤的试验 ,研究了在重力和紊动扩散共同作用下悬移质泥沙运动的有关特性 。
