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

今天，您了解了驻， 以及它们如何由腹组成。

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。

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

所以峰是腹， 不振荡点是。

(including those near any open ends of the pipe) form the peaks, and therefore the antinodes.

（包括声门尖端）构成 顶点，以及位移中心。

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 在他们身上，最偏移中心。

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

这是您可以拥有最简单驻， 具有最少腹。

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

今天，我们了解了驻，以及如何 由点偏移中心组成。

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

每个覆盖添加一个点一个偏移中心。

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 顶部在示器中。

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，而是 每端中心偏移。

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

那么二次谐频率呢... 具有 3 个点两个偏移中心驻？

Then, the 2nd harmonic will have three antinodes and two nodes, and so on.

那么，二次谐有3个中心 偏移量，两个，等等。

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

开放端将是一个腹， 因为那是振荡达到峰值地方。

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

所以顶点是位移中心， 不动点是点。

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.

驻不振荡点称为，峰最大高度处点称为腹。

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 查看点位置偏移中心。

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将有两个腹，一个位于中间。

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有 3 个点——每端一个，中间一个——加上点之间 2 个腹。

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与具有两个固定端相反：它不是在每一端都有一个，而是在每一端都有一个腹。
