5、1- Cpa0 )校核设计船横剖面面积曲线的Cp 和 Xb：在 AutoCAD 中用面域求得图形的 Cp=0.6041， Xb=-0.582。而设计船的Cp=0.6047，Xb=-0.584，棱形系数和浮心纵向位置均在误差允许的范围内，所以此次的“ 1-Cp”法变换母型船得到的横剖面面积曲线符合设计船的要求。“1-Cp”法是将横剖面面积曲线在船中剖面处分成前后半体，分别无因次化的。前后体各站移动的距离分别为：前体站数56788.599.510x0.000.200.400.600.700.800.901.00 x-0.01-0.01-0.01-0.010.000.000.000.00变化后的值-

7、其他高度方向的数值则除以型深。 这样就得到母型船的无因次化型值表。八用作图法插出设计船的无因次化型值表1、找出与设计船某站横剖面面积相同的母型船对应剖面的位置，如A-A 剖面为对应于设计船第8 站剖面的母型船横剖面位置；2、在母型船半宽水线（无因次）图上，量取A-A 剖面位置上各水线的半宽值，作为设计船第8 站横剖面上各水线半宽（无因次） ；3、依次类推，设计船所有站的各水线半宽（无因次）都可以这样得到，从而就得到设计船的无因次化型值表。九将设计船型值表因次化将宽度方向的数值乘设计船的半宽，将长度方向的数值乘设计船的半长，各吃水值乘设计吃水， 其他高度方向的数值则乘型深。 这样就得到设计船的有
