Instead, it has an atmosphere made up of chemicals such as vaporized sodium, potassium and gaseous titanium oxide, which absorb light, but that still does not explain the planet's extreme blackness.

相反，TrES - 2b的大气层由气态钠、钾和三氧化钛这些可以吸收光线的化学物质组成，不过这也并不能为该行星极黑提供解释。

Dr Katz and his colleagues found that, although sodium ions flow readily in between adjacent aluminium-oxide layers of sodium beta-alumina, they cannot pass between them.

Katz博士和他的同事们发现, 在钠β-氧化铝中, 虽然钠离子流很容易在相邻的氧化铝层之间流动, 但是它们无法从中穿过.

Below the glass strain temperature, interdiffusion coefficients are almost independence of sodium oxide concentration in the glasses and somewhat increase with long ion exchange time.

低于玻璃应变温度，互扩散系数几乎不依赖玻璃中的氧化钠浓度，而略随离子交换时间增加而增大。
