金属面，具有强烈的金属质感，并能产生金属光感，有很美的观赏效果。

Metallic finish membrane: with rich metallic texture and luster, capable of creating excellent view.

当在内在视野中看到赫利欧托利频率时，它们呈现出混合了粉彩虹色与淡银色的色彩，相当接近于金属光的频率。

When the Heliotalic frequencies are seen with the inner vision, they appear as pastel, rainbow colors mixed with pale silver, almost like a metallic light frequency.

举个例子来说，我们谈论的临界频率是，光从金属表面逐出一个电子，所需的最小频率。

So, for example, we were talking about a threshold frequency as in a minimum frequency of light that you need in order to eject an electron from a metal surface.

So, for example, here we're showing rubidium and potassium and sodium plotted where we're plotting the frequency -- that's the frequency of that light that's coming into the metal versus the kinetic energy of the electron that's ejected from the surface of the metal.

让大家看来都是可以理解的事情,就是把不同金属的观测结果,画到一张图里面来，例如这里,我们展示的是钠，钾,铷的频率-这是照射金属的光的频率,和金属表面出射电子动能的关系。
