摘　　要：本文较[2]的主要进展在于对摩擦功率以参变量积分获得更精确的解析解并与 Avitzur 公式进行比较.文中还给出辊挤问题的解析解.Comparing with Ref.[2]the main progress deseribed in the present paper is that a more precise analytical friction power by parametric integration is obtained.The corresponding solution is compared with that from Avitzur' s.Furthe- rmore,the analvtical solution for extrusion through idle rolls is also given in this paper.
