关于大型船舶试航测速的浅水修正方法

A Trial Speed Modification Method for Shallow Water Effect

在分析了有关船舶在浅水水域试航航速修正方法的基础上，推荐A．Millward的三因次修正方法用于大型船舶在有限水深水域试航航速的修正。文中给出的算例，表明其航速预报结果同相关方法相比，具有同一量级的精度。本方法可作为大型船舶试航航速修正或预报的一种估算方法。

The effect of water depth on trial speed for ships navigating in shallow water is analyzed in this paper. The Millwards three dimensional modification method is recommended as a base for considering the shallow water effect. The trial result for a ship with large dimensions is taking as an example for analyzing. It is shown that this method is rather practicable to be used for predicating the trial speed correction.
