5、1- Cpa0 )校核設計船橫剖面面積曲線的Cp 和 Xb：在 AutoCAD 中用面域求得圖形的 Cp=0.6041， Xb=-0.582。而設計船的Cp=0.6047，Xb=-0.584，棱形系數和浮心縱向位置均在誤差允許的范圍內，所以此次的“ 1-Cp”法變換母型船得到的橫剖面面積曲線符合設計船的要求。“1-Cp”法是將橫剖面面積曲線在船中剖面處分成前后半體，分別無因次化的。前后體各站移動的距離分別為：前體站數56788.599.510x0.000.200.400.600.700.800.901.00 x-0.01-0.01-0.01-0.010.000.000.000.00變化后的值-

7、其他高度方向的數值則除以型深。 這樣就得到母型船的無因次化型值表。八用作圖法插出設計船的無因次化型值表1、找出與設計船某站橫剖面面積相同的母型船對應剖面的位置，如A-A 剖面為對應于設計船第8 站剖面的母型船橫剖面位置；2、在母型船半寬水線（無因次）圖上，量取A-A 剖面位置上各水線的半寬值，作為設計船第8 站橫剖面上各水線半寬（無因次） ；3、依次類推，設計船所有站的各水線半寬（無因次）都可以這樣得到，從而就得到設計船的無因次化型值表。九將設計船型值表因次化將寬度方向的數值乘設計船的半寬，將長度方向的數值乘設計船的半長，各吃水值乘設計吃水， 其他高度方向的數值則乘型深。 這樣就得到設計船的有
