If fusion was taking place, then neutrons flying through the plastic would cause protons within the material to recoil, leaving telltale tracks.

如果发生巨变，穿过塑料的中子就会引发材料内质子反冲，从而留下痕迹。

Massive stars normally die when they run out of material to sustain nuclear fusion, and all that's left in their cores is inert iron.

大质量恒星死亡时，它们通常运行的材料进行维持核聚变，以及所有在其核心的左边是惰性铁。

Those white dwarf stars that find themselves near a "companion" star can draw material from their neighbour, building up to a critical mass and eventually sparking nuclear fusion again in a nova.
