内河运输船舶的吨位与面积关系研究

Research on Relationship Between the Tonnage and Area of Inland Vessels

探讨内河运输船舶的吨位与面积之间的关系,将有助于合理有效地计算船闸的一次过闸平均吨位.采用最小二乘回归分析的方法,分析标准船型、实际(抽样)船舶和船舶流量的吨位与面积关系,结果表明内河运输船舶的吨位与面积之间具有显著的相关性,可采用线性、二次多项式、幂函数等函数进行回归分析;而统计意义上单位时间内船舶流量的吨位与面积之间具有良好的线性关系.应用时,实际船舶的吨位与面积关系可采用相应的标准船型来代替.

The relationship between the tonnage and area of inland vessels is needed to calculate the average lockage tonnage reasonably.In this paper,regression analysis was used to study the relationships of inland standard ＆amp; actual（sampling） vessels and unit vessel flow rate.The results show that the relationship is evident and can be described with a linear equation,or a quadratic polynomial,or a power function.And the area is linear with the tonnage for unit vessel flow rate.In practice,the relationship of actual vessels can be replaced by that of standard vessels.
