I read the story from the front to the end cover and let me tell you something.

我从头到尾读了这个故事， 让我告诉你一些事情。

Remember how the fundamental wave for a string with two fixed ends covered half of a wavelength?

还记得和弦的基本波是如何产生的吗？ 两个固定端覆盖一半波长？

So we saw price rises coming in after those covered lockdowns ended but then we had an energy crisis come about because of the war in Ukraine.

因此，在这些有保障的封锁结束后，我们看到价格上涨，但随后由于乌克兰战争，我们发生了能源危机。

Remember how the fundamental wave for a string with two fixed ends covered half of a wavelength? The fundamental wave for a pipe with two open ends also covers half of a wavelength.

还记得两端固定的弦的基波是如何覆盖半个波长的吗？具有两个开口端的管道的基波也覆盖半个波长。
