This article analysis the reason of backnullend whip problem and especiallysolves the real question that is optim ization laying pipe curve. Therefore it solves the backnullendwhip problem from thebasis.KEYWORDSnull H igh speedw ire linenull Laying headnull Backnullendwhipnull Curvenull null S = v 1 20W E M 7 S ,d H S L 3 L b a X : # r b S 5 L 3 / ,S = 9 B t L 3 ! !
