Sommario

Questa memoria studia l'effetto della variazione di velocità di una distribuzione oscillatoria di pressione superficiale in un intervallo di tempo finito t0, sull'onda generata a partire dalla quiete. Si trova che questa accelerazione produce lo stesso sistema di onde di regime che si avrebbe se la pressione iniziasse complessivamente con velocità uniforme al tempo t=t0. L'effetto dell'accelerazione iniziale è sentito nella parte transitoria del sistema di onde.

Summary

This paper studies the effect of variation of velocity of the oscillatory surface pressure distribution over a finite time interval t0 on the wave generated from rest. The result of such an acceleration is found to produce the same steady state wave system as it would be if the pressure started impulsively with the uniform velocity at t=t0. The effect of initial acceleration is felt in the transient part of the wave system.
