采用改性PGS和Ce~(4+)作为氧化还原引发剂引发的原位插层聚合法得到了坡缕石/聚丙烯酰胺杂化物。

The characteristic and difference of flow in porous media between the pseudo-plastic fluids and the expansile fluids was described in detail. The experimental pressure drop measurements were made in a packed bed under a variety of conditions, and the variation of the friction factor with the Reynolds number was obtained. Corresponding to the flow resistance in a nonporous channel, the flow resistance in porous media can be divided into Darcy resistance and Forchheimer resistance as well. The experiment data was divided into Darcy regime, transitional regime and Forchheimer regime in accordance with the Reynolds number.
