在以后的七个实验中得到的风在水面上的剪应力τ0值与弗朗西斯（1951）的数据进行了比较。四组新的数据表明，应力系数C = τ0/τ u2不是常数，而是随风速u（τ =空气密度）而有所增加。三组数据仅仅显示了C的大的实验分散性，并且不支持任何一致的阻力定律。本文还讨论了τ0主要是由小波纹的阻力而不是由大浪的阻力引起的理论。
Values for the shear stress τ0 of the wind on a water surface, found in seven later experiments, are compared with the data of Francis (1951). Four sets of the new data show that the stress coefficient C = τ0/ϱu2 is not constant, but that it increases somewhat with windspeed u (ϱ = air density). Three sets merely show a large experimental scatter of C, and do not support any consistent law of drag. A theory is also discussed that τ0 is mainly caused by the drag of the small ripples, and not by the drag of the big waves.
