氧气气氛下再生,有利于聚集态的钯金属粒子转化为分散态的Pd~(2+),促进了催化剂活性恢复。
The catalyst activity is restored when the regeneration is performed at oxygen atomosphere because Pd particle in aggregation state can be converted to Pd2 + in dispersion state .

当宇宙冷却,粒子不再转化回能量的形式。
As the Universe cools , the particles stop changing back into energy .
-
相互作用有可能引起粒子态转化为负能态,因此在其框架内人们不能够指望物质是稳定的。
Interaction may cause transitions to negative energy states , so that there is no hope for a stability of matter within that framework .
