本文收集了1970年以来国内外一百余艘集装箱船的实船资料,对其主要船型参数的规律作了初步探讨。并运用逐步回归分析的方法,借助电子计算机的大量运算,选出最优回归方程,整理概括出了一组适合集装箱船舶的、多变量的主要船型参数统计公式。同时,与国内外已发表的有关统计公式作了比较。本文提出的统计公式,由于考虑的因素较多,虽然形式比较复杂,但其精度较高,适用于电子计算机对船型参数进行初步估算。文中对大型集装箱船的主要船型参数发展的一般趋势,也作了简要叙述。
This paper collects the real ship data of more than one hundred container ships at home and abroad since 1970 and makes a preliminary discussion on the law of its main ship parameters. By means of stepwise regression analysis, the optimal regression equation is selected by means of a large number of computational computations of electronic computers. A set of statistic formulas of multivariable main types of ships suitable for container ships are summarized. At the same time, it has made comparisons with relevant statistical formulas published at home and abroad. The statistical formula proposed in this paper, due to many factors considered, although the form is more complex, but its accuracy is high, suitable for electronic computer to initially estimate ship parameters. The general trend of the development of the main vessel parameters of large container ships is also briefly described.
