| 1. | Wave speed equals frequency times wavelength .
波速等于频率乘以波长。 |
| 2. | The higher modes have shorter periods than the fundamental mode and, moreover, they have higher velocities .
高振型波比基阶振型波周期短，波速高。 |
| 3. | this clearly indicates that uniqueness is reached provided that the irrotational and equivoluminal wave velocities, and are real and nonzero.
这就清楚地表明，如果无旋波速度和等体积波速度是不等于零的实量，则唯一性是成立的。 |
