设计水线面 meaning in English

designed waterplane
disigned waterplane

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:本文通过甲板面面积系数和设计水线面面积系数的外层叠代、甲板面变换和横剖面面积曲线变换的自身内层叠代,在保持横剖面面积曲线不变的条件下,获得满足设计水线面系数变化要求的新船型,而不必寻找横剖面线的变换函数来实现设计水线面的变换,本方法是对传统的母型船变换的一个有益补充。
