As a continuation of the study of waves passing through a medium with periodic structure, the wave equation in a medium where elasticity varies regularly is treated as one of Hill's equation. The same form of the equation appears in the long wave passing through a canal with undulatory bed. It is shown that, the solution in terms of Fourier series given in early investigations is inadequate in this problem, although that solution is very simple in solving process, treatment, etc.
今まで速度が規則的に変わっている様な不均質媒質を伝わる波動の安定性について考察を進めて来た.その研究の続きとして今回は弾性が規則的に変わっている場合を取扱った.
