Abstract : by both the external combination of deck coefficient and designed water - line coefficient ? and the in - ternal combination of deck transformation and cross - section area curve transformation ? a new ship line is generated on the condition that cross - section area is the same as the basic ship and designed water line satisfies the need . this method needs not look for any transformation function to finish the change of cross - section area curve . it is a profitable development to the traditional lackenby method 文摘:本文通過甲板面面積系數和設計水線面面積系數的外層疊代、甲板面變換和橫剖面面積曲線變換的自身內層疊代,在保持橫剖面面積曲線不變的條件下,獲得滿足設計水線面系數變化要求的新船型,而不必尋找橫剖面線的變換函數來實現設計水線面的變換,本方法是對傳統的母型船變換的一個有益補充。
