Measurements of noble gas (helium, neon, argon, krypton, and xenon) partitioning between silicate melt and iron melt under pressures up to 100 kilobars indicate that the partition coefficients are much less than unity and that they decrease systematically with increasing pressure. The results suggest that the Earth's core contains only negligible amounts of noble gases if core separation took place under equilibrium conditions.
在高达 100 千巴的压力下测量硅酸盐熔体和铁熔体之间的稀有气体（氦、氖、氩、氪和氙）分配表明，分配系数远小于 1，并且随着压力的增加而系统地减小。如果核心分离是在平衡条件下进行的，那么这些结果表明地球的核心只含有微不足道的稀有气体。
