Most of the time the lasers are dark, producing areas of light with low intensities with the occasionally brief but brilliant flashes of high - intensity light.

大部分的时间里激光是暗的，产生低强度的光区伴随着偶尔短暂的高强度光的闪烁。

So, what we would expect is that there is a relationship between intensity in kinetic energy because it was understood that however intense the light was, if you had a more intense light, it was a higher energy light beam.

光强和能量之间,应该有一定的关系,因为在我们的理解中,不管光强是多少，光的强度越大,光束能量越高。

The next thing that they wanted to look at was the actual intensity of the light and see what the relationship of intensity to kinetic energy is.

下一而他们要研究的是光的强度,看一下光强和能量之间的,关系是怎样的，我们预期。

So that should mean that the energy that's transferred to the electron should be greater, but that's not what you saw at all, and what you saw is that if you kept the frequency constant there was absolutely no change in the kinetic energy of the electrons, no matter how high up you had the intensity of the light go.

所以这意味着转移到电子,上的能量也越大，但这并不是，我们观测到的现象,我们所看到的是,如果固定光的频率不变,不管光强如何变化,电子的动能没有任何变化。
