They need to provide maximum energy, but they must also be compact and light for easy transport.

它们需要最大限度的提供能量，但是又得轻巧、便于运输。

Photosynthesizing cells could mostly harness energy at their surfaces, which limited their maximum energy production, which limited their evolutionary avenues somewhat.

光合作用的细胞主要在其细胞表面上利用太阳能，这限制了它们能源产量上限，也在某种程度上限制了它们的进化途径。

It doesn’t change their maximum kinetic energy.

它不会改变它们的最大动能。

It doesn't change their maximum kinetic energy.

它不会改变其最大动能。

And when you increase the intensity of the light, does that affect the maximum kinetic energy of the ejected electrons?

而当光的强度增加时，这会影响被移除电子的最大动能吗？

So, the logical end step for maximum energy harvesting is to harvest it directly from the Sun from one of three different types of Dyson spheres.

因此，为了获取最多的能源，按逻辑推理的最终步骤是，直接从太阳上收集能量，从三种不同类型的戴森球体中选择一种。

This means that increasing the intensity of the light increases the number of electrons ejected, but it doesn’t affect their maximum kinetic energy.

这意味着增加光的强度会增加射出的电子数量，但不会影响它们的最大动能。

This equation tells you that if you increase the frequency of the light, the maximum kinetic energy of the electrons should increase accordingly.

这个方程告诉你，如果你增加光的频率，电子的最大动能也会相应增加。

This means that increasing the intensity of the light increases the number of electrons ejected, but it doesn't affect their maximum kinetic energy.

这意味着增加光的强度会增加去除的电子数量，但不会影响它们的最大动能。

But the electrons with the maximum kinetic energy will be the ones that took the bare minimum amount of energy to separate from the metal.

但是具有最大动能的电子将是从极板分离所需能量最少的电子。

Turns out, there is a cutoff frequency, and the higher the frequency is above the cutoff, the higher the maximum kinetic energy is of the electrons.

原来，有一个截止频率， 高于截止频率的频率越高，电子的最大动能就越高。

So you eject more electrons, and these electrons have a higher speed, and achieve a higher maximum kinetic energy, which is the kinetic energy of the fastest-moving electrons leaving the plate.

所以你射出更多的电子， 这些电子的速度就更高， 达到更高的最大动能，也就是运动最快的电子离开极板的动能。

But not only have we seen a decrease in hurricane landfall over the last century, we also haven't seen a significant increase in seasonal accumulated cyclone energy which measures maximum wind energy over the course of a season.

但我们不仅看到上个世纪飓风登陆次数减少，而且我们也没有看到季节性累积气旋能量显着增加，该能量衡量一个季节的最大风能。
