另外一个有冰存在的迹象就是陨石坑底部的并行线和无核物质。

Another sign of ice is the presence of parallel lines and pitted material on the crater floor.

在陨石坑口壁上也发现了并行线一样的裂缝，这可能是由于含冰物质热收缩现象造成的。

Parallel linear cracks are also observed along the crater wall over the gullies, which could be due to thermal contraction of ice-rich material.

在隔离状态下镓盐与有机复合物皆不导电，但Hla和他的同事们有证据表明由这两种物质组成的金属线有超导特性。

In the isolated state gallium salt and organic compounds are non-conductive but Hla and his colleagues have evidence that these two substances formed by the metal lines are superconducting properties.

All right. The other thing I have to teach you is matter-energy interaction so that we can see how the Balmer series validates the Bohr model.

好的，我要教你们的里一个知识点是,物质能量的相互作用，我们可以见证,巴尔末线系是怎样证实波尔模型的。
