空船重量误差的分析

Analyses of the accuracy of light ship weight

从吃水的观测、船舶建造、静水力曲线图的绘制、倾斜试验方法等角度分析空船重量的误差，提出了空船重标准差的表达式，以实例证实了２万吨级船舶的空船重量的标准差为３０ｔ左右．

This paper analyses the accuracy of draft reading, shipbuilding, static curves plotting and inclining experiment and develops the formulas for the calculation of standard deviation of light ship weight. The results obtained through real ship particulars are of practical significance.
