船舶各主要尺度間的比值也是表示船體幾何特征的重要參數(shù)。常用的尺度比有長(zhǎng)寬比（L/B）、寬度吃水比（B/d）、型深吃水比（D/d）及長(zhǎng)深比（L/D）等。它們與船舶性能、強(qiáng)度以及經(jīng)濟(jì)性等有密切的關(guān)系。三、尺度比(dimensionratio)ChapteroneHullformandapproximatecalculation1-2節(jié)：船體型線圖shiplinesplanChapteroneHullformandapproximatecalculationBodyplan橫剖型線圖ChapteroneHullformandapproximatecalculationProfileorsheerplan縱剖線圖ChapteroneHullformandapproximatecalculation

（1-10）在實(shí)際計(jì)算中，也可將式（1-10）和（1-11）寫(xiě)作或

（1-11）式中：括號(hào)內(nèi)各縱坐標(biāo)值前的系數(shù)（1，3，3，1）也稱為辛氏乘數(shù)，為各辛氏乘數(shù)之和。式（1-15）或式（1-16）稱為辛浦生第二法。又簡(jiǎn)稱辛浦生[1，3，3，1]法。ChapteroneHullformandapproximatecalculation
