当我们算出了在各个恒星中锂原子的总数，同位素锂- 7的总量仅是在那里应有量的三分之一。
When we count up the lithium atoms held in stars, there is only one-third as much of the lithium-7 isotope as there should be.
效果最为强烈的便是锂元素的形成，这种元素有两种同位素。
The most dramatic effect would have been on the formation of lithium, an element that has two isotopes.
所以，目前锂同位素的含量应该比标准模式预测的少。
So, there should be less of this isotope around than the Standard Model predicts.
