| 摘 要： | 如何准确、快速、简便地估算船舶在波浪中的失速，已成为船舶研究、设计人员及航运界有关人员共同关心的一个重要课题。文中给出了近似估算运输船舶在波浪中失速的2个方法。对处于初步设计阶段且尚未做过静水快速性能模型试验的运输船舶，可直接应用第2个方法。该方法提出的近似估算公式应用方便，也不用编程便可直接人工计算，且与模型试验结果相当吻合。

| Abstract: | How to estimate ship speed loss in waves correctly and conveniently has been concerned commonly by researchers in ship research, design, building and navigation fields, Two methods of approximate estimation for ship speed loss in waves are given. One is the estimation for ship speed loss in waves by estimating ship resistance increment in waves, the other is an approximate formula for estimating ship speed loss before carrying out powering performance tests in calm water. This formula can be conveniently applied, with which the calculation can be carried out manually without compiling program, and its calculation results agree with model test data very well. |
