摘要：
Experimental results of drag reduction using microgel type and linear type of Napolyacrylate are described. The microgel type showed no drag reduction effects and suppressed the drag reduction effects of the linear type. This indicates that elastic components in the fluid dose not necessarily have the drag reduction effect. Dependencies of drag reduction effect of the linear type on salt concentration and pH indicated that more extended conformation of polymer induces more drag reduction effect.
