5、p和Xb 通过以上数据，用辛浦生可求得设计船实际棱形系数Cp=0.6104，与设计值0.610相差小于0.1%，在允许误差范围内，说明满足要求。 同理，可计算设计船的Xb=-0.02083，与设计要求的Xbz=-0.02074相差小于0.1%，所以此设计既为所求五.型线图绘制将相应的值分别除以Cb，B，和d，便得到母型船型值表的无因次值吃水无因次化尾端点距舯尾端点半宽半宽半宽半宽半宽半宽半宽半宽半宽站号0.000 0.500 1.000 1.500 2.000 3.000 4.000 5.000 船底-0.489090.0138080.030 0.031 0.031 0.031 0.031 0
