摘　　要：本文以5艘双断级滑行艇模型的试验数据为基础,采用多元线性回归的方法对试验数据进行回归分析,从而导出在不同断级参数情况下双断级滑行艇的阻力回归公式。通过相对误差分析法验证了回归公式的精确性,并根据回归的结果绘制成图以供设计参考。Based on the model test data of five double-stepped planing crafts,the multiple linear regression method was used to treat the test data and thus a resistance regression formula was obtained for the craft with different parameters of its double steps.Then,the accuracy of the regression formula was verified through the relative error analysis.Finally,the regression results were plotted in charts so as to be references for design.
