海洋中深度一致的洋脊就像长波的波导。一个均匀的矩形脊被用作一个简单的模型，它示出，在这种情况下，一个无限数量的模式的传播沿着脊是可能的。实际的色散曲线的数值例子的基础上，大西洋中脊。在一般形状的脊的情况下，一个简单的变分技术建议作为实现数值解的一种手段。这些技术的两个数值例子。文末考虑了地球自转的影响，数值算例表明，地球自转的影响很小。
A ridge in an ocean of uniform depth acts as a waveguide for long waves. A uniform rectangular ridge is used as a simple model, and it is shown that in this case an infinite number of modes of propagation along the ridge are possible. Actual dispersion curves are given for numerical examples based on the Mid-Atlantic Ridge. In the case of a ridge of general shape, a simple variational technique is suggested as a means of achieving numerical solutions. Two numerical examples of these techniques are given. The effect of the Earth’s rotation is considered at the end of the paper, and it is shown that in the numerical examples in this paper, this effect is very small.
