主要的差别是,相比于太阳,阿连德陨石缺失了大部分的挥发性元素,例如氢、碳、氧、氮和稀有气体。
The major difference is that Allende is depleted in the most volatile elements, like hydrogen, carbon, oxygen, nitrogen, and the noble gases, relative to the Sun.
任何其他的挥发性元素也在该步中除去。
结果表明:煤中氟属于强挥发性元素,在煤灰中是非浓集的。
Experimental results identified that fluorine in coal belong to volatile elements, fluorine in fly ash and bottom ash were non rich.
类地行星挥发性元素普遍亏损很可能是由于太阳星云早期剧烈的太阳活动引起的。
The common depletion of volatile elements in terrestrial planets was probably caused by the early violent activities of the inner solar nebula.
这可能是因为月球形成过程中,撞击产生的热能使挥发性氢元素——水的重要组成成分——大量流失。
