In references to the log speed vector is defined mistakenly on the leeway track,and therefore the method of dead reckoning provided in wind and current is mistaken too.
在［１］～［４］中，都错误地将计程仪船速矢量定义在风中航迹线上，因而，在此基础上提出的有风有流情况下的航迹推算方法也是错误的。
Methods of the ship model self-propulsion test in regular waves,the data processing and expression of the frequency response curves of self-propulsion factors in the regular waves,the spectrum analysis statistics prediction of power in irregular waves and the prediction of ship speed loss in irregular waves are described.
阐述了船模规则波自航试验的方法、规则波中自航因子频率响应曲线的数据整理和表达方法、不规则波中收到功率的谱分析统计预报方法,并给出了不规则波中船舶的失速预报方法。
