用蜂窝夹芯管代替夹砂管的可行性试验研究

Experimental Study on Replacing RMP with Honeycomb Core Pipe

本文主要研究用蜂窝结构代替夹砂层的可行性，通过理论和试验分析是可行的，但目前还存在工艺方面的问题，需要进一步改进。

The feasibility of replacing Sand filler layer with honeycomb structure is studied in this paper, theory and experiment approve the feasibility,but there still exist technical process problems.
