The bottom line, he says, is that "the only process we are aware of that could cause such large isotope scatter is if the hydrogen content of the moon is 10,000 to 100,000 times less than [on] Earth.
We systematically calculated the isotope distributions of limiting temperatures for a series of nuclei from light to heavy nuclei, and obtain a thermal stability line for hot nuclei.
系统地计算了从轻到重的一系列元素极限温度的同位素分布，并从中抽取出热核的热稳定曲线。
