摘　　要：本文建立与Ａｖｉｔｚｕｒ不同的直角坐标系速度场与应变速率场，并采用变上限积分与参变量积分获得辊拔力的上界解析解。Tlie velocity and strain-rate fields which are different from AVITZUR's have been established in Cartisian coord inates. Using the integral as a function of the upper limit and integration depending on a parameter, an analytical upper bound solution to drawing stress through idling rolls has been obtained in this paper.
