本文对改进后的Dawson方法作了简单的描述,并且给出了船舶在开阔无限水深的海域、限制航道、凹型海底以及其他水下结构物存在的海域中航行时的计算例子.结果显示了改进后的Dawson方法以及计算程序的有效性,是一种可以用来预报不同工程问题中船舶兴波和船舶水动力的简单而实用的方法.%The method developed based on Dawson's approach is simply described in this paper. Theresults of a ship moving in open water, a channel and water with concave - shaped bottom and other sub-merged structures obtained from the modified method are discussed. It shows that the modified Dawson' smethod and the program developed here are valid and can be applied to many different engineering problemson ship waves or ship hydrodynamics.
