And then if we look at these troughs right here, or these antinodes, rather, those are going to be areas where we have total constructive interference.

然后，如果我们观察些波谷，或者更准确地说， 些反节点， 它们将成为我们拥有完全建设性干扰区域。

Today, you learned about standing waves, and how they're made up of nodes and antinodes.

今天，我们了解了驻波，以及如何 由节点和偏移中心组成。

And the open end will be an antinode, because that’s where there’s a peak in the oscillations.

开放端将是一个波腹， 因为那是振荡达到峰值地方。

But the areas where molecules oscillate the most (including those near any open ends of the pipe) form the peaks, and therefore the antinodes.

但是分子振荡最多区域（包括管道任何开口端附近区域）形成峰，因此形成波腹。

You will have these little nodes and antinodes, but they are made up of traveling waves interfering with each other, bouncing back and forth.

看到些小小波节和波腹，它们是由行波相互干涉、来回反弹形成。

If you look at a string on a stringed instrument, you can actually see where the nodes and antinodes are.

如果我们看弦乐器弦，我们可以 查看节点位置和偏移中心。

It’s the simplest possible standing wave you can have, with the fewest nodes and antinodes.

是您可以拥有最简单驻波， 具有最少波节和波腹。

Today, you learned about standing waves, and how they’re made up of nodes and antinodes.

今天，您了解了驻波， 以及它们如何由波节和波腹组成。

Overtones build on the fundamental, incrementally: each overtone adds a node and an antinode.

每个覆盖添加一个节点和一个偏移中心。

Instead of having a node at each end, it has an antinode at each end.

不是在每一端都有一个结，而是 每端中心偏移。

A standing wave in a pipe with two open ends is kind of the opposite, of the wave with two fixed ends: Instead of having a node at each end, it has an antinode at each end.

具有两个开口端管道中驻波与具有两个固定端波相反：它不是在每一端都有一个波节，而是在每一端都有一个波腹。

So the peaks are the antinodes, and the points that don't oscillate are nodes.

所以顶点是位移中心， 不波动点是节点。

The points of a standing wave that don’t oscillate are called nodes, and the points at the maximum height of the peaks are antinodes.

驻波不振荡点称为波节，波峰最大高度处点称为波腹。

So the fundamental standing wave for a pipe with two open ends will have two antinodes, and one node in the middle of the wave.

因此， 具有两个开口端管道基本驻波将有两个波腹，一个波节位于波中间。

And the open end will be an antinode, because that's where there's a peak in the oscillations.

开口端将是一个位移中心，因为 顶部在示波器中。

The second-simplest standing wave you can have on a string with two fixed ends has 3 nodes -- one at each end, and one in the middle -- plus 2 antinodes in between the nodes.

具有两个固定端弦上第二简单驻波有 3 个节点——每端一个，中间一个——加上节点之间 2 个波腹。

Now what about the frequency of the second harmonic -- the standing wave with 3 nodes and 2 antinodes?

那么二次谐波频率呢... 具有 3 个节点和两个偏移中心驻波？

It's the simplest possible standing wave you can have, with the fewest nodes and antinodes.

它是可以获得最简单驻波 在他们身上，最低结和偏移中心。

So the peaks are the antinodes, and the points that don’t oscillate are nodes.

所以峰是波腹， 不振荡点是波节。

And in its most basic form, it would have just one antinode, in the middle.

在其最基本形式中，它将具有 中间有一个位移中心。
