英文摘要	The experimental results on drag increment caused by internal waves, which are generated by a Rankine ovoid towed horizontally at constant velocities in a two-layer stratified water (a strong pycnocline) initially at rest, are presented. The drag increment due to stratification is obtained experimentally as a function of internal Froude number Frd and Reynolds number Re. From the results, it is shown that as a function of Frd or Re, an increment in mean drag coefficient due to stratification DeltaC(d) has both increasing and decreasing region attributable respectively to internal wave and to collapse of mixing fluids in the wakes. A most significant result shows that when Frd = 0.838 there exists a maximum of DeltaC(d), which is equal to 0.05 in the exciting region of the strong internal wave generation.
