Some of their work involved X-rays produced by particle accelerators, devices that bring atomic particles into high energies.

If a photon, which has no mass, can behave as a particle --And we know this.

如果一个没有质量的光子，像粒子一样运动--，我们知道这个。

So this validates de Broglie and it also validates the whole concept of wave-particle duality.

这就证实了德布罗意的观点,也证实了,波粒二象性的原理。

It says climate change models show particle-producing fires will continue to increase in both frequency and intensity with rising global temperatures.

So, it turns out that the photoelectric effect is not the only evidence for the fact that light has these particle-like characteristics.

所以，原来是光电效应,不是唯一的证明光具有,粒子特性的证据。

Then, I gave you one other very important example of a particle moving in the x-y plane.

下面我再拿一个重要的例子,质点在 x-y 平面内的运动

And there is no way to explain this phenomenon if you model the water as having particle-like properties.

没有其他的方法来解释这种现象,除非认为,水是一种具有粒子的性质。

There is no way that you could irradiate a crystal of nickel with a single beam of x-rays and get that circular ring pattern if the electron beam were behaving as a particle beam only.

没有什么其他的途径,可以让镍晶体发射,单束X光来,继而得到环状图案,如果电子束,是以粒子束形式出现的。

Our picture now is going to be some particle that's traveling in the x-y plane.

我们现在的情景是在 x-y 平面内,运动的质点

that the negative particle travelled - it was deflected much, much further by those plates, what he could also assume and make the conclusion of is that the mass of that negative particle is actually larger or smaller?

因为他发现负电粒子,运动了很远,它被两块电板偏转了,非常非常远,所以他给出的结论是,负电粒子的质量,是比较大还是比较小？

And the reason that quantum mechanics is going to work where classical mechanics fails is that classical mechanics did not take into account the fact that matter has both wave-like and particle-like properties, and light has both wave-like and particle-like properties.

上发生的行为,量子力学得以成功,而经典力学却失败的原因,是因为经典力学,不能包容物质的，波动性和粒子性,和光的波动性和粒子性。

We said, "Let's take, for the simplest case that we can possibly imagine, namely a particle moving in one dimension along the x-axis with a constant acceleration a.

我们说过,"考虑我们可以想象的最简单的情况,即质点在一维空间运动,沿着 x 轴且保持恒定加速度 a

And that's the following. Let's take a particle that is moving in the x-y plane, so that at one instance-- sorry, let me change this graph-- is here--oh, this is bad.

接下来,我们来看一个物体,在 x-y 平面内运动,在这个例子中,对不起,我要重画一下这个图,在这里,这画得不好

For example, suppose you use vertical motion and you use y instead of x; and a would be g or -g; that's a particle falling down under the affect of gravity.

例如,假设在竖直运动中,你用 y 来代替 x,那么 a 就是 g 或者 -g,这就是一个受重力作用下落的质点
