本文试图确定细长鱼能做什么样的横向振荡运动才能使它获得高的弗劳德推进效率。推荐的程序是使鱼以所需的游泳速度左右的速度沿其身体传递波，振幅从前部的零增加到尾部的最大值，其跨度应超过某个临界值，并且该波形包括正相位和负相位，从而使角反冲最小化。附录部分对变形体细长体理论进行了综述。
The paper seeks to determine what transverse oscillatory movements a slender fish can make which will give it a high Froude propulsive efficiency, The recommended procedure is for the fish to pass a wave down its body at a speed of around of the desired swimming speed, the amplitude increasing from zero over the front portion to a maximum at the tail, whose span should exceed a certain critical value, and the waveform including both a positive and a negative phase so that angular recoil is minimized. The Appendix gives a review of slender-body theory for deformable bodies.
