用跳动光、飘浮光取代固定光。

Beat with light, replace the fixed-floating light.

但光点留在固定的位置彼此相对——打个比方，就像星座。

But the points of light stay in fixed positions relative to each other-making, for example, constellations possible.

因此大部分的光伏阵列使用固定支架指向南面(或北面如果你位于赤道以南)。

So most PV arrays use fixed mounts that face south (or north if you are below the equator).

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。
