Neon is a noble gas that is colorless and odorless.

氖是一种无色无味的惰性气体。

These could be a liquid noble gas, germanium and silicon crystals, a refrigerant, or other materials.

它们可能是液态惰性气体、锗、晶体硅、制冷剂或是其他材料。

The water vapor evaporation and condensation at the bubble wall and the water vapor diffusion versus the noble gas inside the bubble are also considered.

同时考虑了水蒸气在气泡壁上的凝结与蒸发以及水蒸气在气泡内相对惰性气体的质量扩散。

Because of the high electronegativity of the positively charged noble-gas centers, any ligands for those centers must themselves be electronegative.

因为带正电的稀有气体中心具有高的电负性，所以，该中心的任何配体必须自身具有电负性。
