摘　　要：文中给出了利用一艘3 m玻璃钢标准船模进行重复拖曳阻力试验的情况,采用ITTC建议的不确定度估计方法,对试验结果进行了综合分析,计算出在给定傅氏数下各阻力系数(Ci)的偏差限、精度限和总不确定度.文中还对该船模的形状因子(1+K)、傅汝德数(Fr)以及水状态(破水阻力R)进行了不确定度分析,并给出了分析的结果.Repeated resistance tests of a standard ship model were conducted in a towing tank at Harbin Engineering University. Test results were analyzed and deviation limits related to precision were calculated, as well as uncertainty estimates in the form of Froude numbers. Finally, the uncertainties of the form factor （1＋k）, Froude number （Fr）, and the breakwater resistance of the ship model were analyzed.
