1. These can cause vibration and damage the blades of the turbines. 这些(气泡)会引起振动并损坏涡轮机的叶片。
2. An earthquake is a vibration that travels through the earth's crust. 地震是一种穿过地壳的震动。
3. As snow accumulates on a steep slope, it reaches a critical point at which the slightest vibration will send it sliding into the valley below. 当雪在陡峭的斜坡上堆积时,它会达到一个临界点,在这个临界点上,最轻微的震动就会使它滑进下面的山谷。
4. So musical instruments evolved in ways that optimize their acoustical properties, how the instrument vibrates and sends those vibration through the air to our eardrums. 因此,乐器的进化优化了它们的声学特性,且优化了乐器振动的方式,并将这些振动通过空气传到我们的耳膜。
5. The electricity companies spend a lot of money each year, cutting the harm of transformers, trying to quiet the noise and maintaining equipment that is constantly affected by vibration. 电力公司每年花费大量资金,减少变压器的危害,试图降低噪音,维护经常受到振动影响的设备。
