摘　　要：基于肥大型船的快速性试验数据,通过对传统估算公式结果的分析及船舶伴流成因的研究,选定部分船型参数及无因次量作为影响因子,建立线性数学模型,采用逐步回归法得到一种新的、更加精确的肥大型船伴流分数估算方法,通过实例验证其精确性和正确性。Based on dozens of the speediness test data of full form ships , through the analysis of the traditional estimation formula and the study on formation cause of the ship＇s wake, part of ship form parameters and dimensionless quantity were select-ed as impact factor to establish the corresponding mathematical model .A new, more precise full form ship wake fraction estima-tion method was proposed by stepwise regression , whose accuracy and correctness were verified by some computation .
