摘　　要：分析了不同方法应用于偶极子影响系数的计算,并详细介绍了Gauss-Bonnet定理在偶极子影响系数计算中的应用。探讨了这些计算方法的近似处理及由此造成的误差,进而以Gauss-Bonnet定理为基础提出了计算偶极子影响系数的修改办法。将此种修改办法应用于面元法的计算中,以×××桨及×××桨为计算对象,分析修改前后的偶极子计算方法对计算结果精度的影响。从理论上探讨了面元法中,有关偶极子影响系数计算环节的误差及减小此部分误差的办法。Different methods used in the calculation of dipole influence coefficient were analyzed and the Gauss-Bonnet theory was introduced in detail.The approximate treatment applied to these methods was discussed and the error result from the treatment was analyzed.Then a modified calculation about dipole influence coefficient based on Gauss-Bonnet theory was proposed.The modified method was used in surface panel method,and the propellers DTMB××× and DTMB××× were analyzed by the surface panel method.The result was compared to the calculation without modification.In the end,the error induced by the calculation of dipole influence coefficient was discussed.
