粒子转化

实物粒子转化为光子的条件

Conditions that entity particles transform into photons

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 .

采用甲基丙烯酸甲酯时，粒子直径随转化率呈直线增大，这就表明粒子发生了聚集。

With methyl methacrylate the particle diameter increases linearly with conversion indicating particle aggregation .

本文利用自制云雾室把微观粒子的运动转化为宏观现象，从而供实验观察和研究。

The moment of microcosmic particles is changed into macroscopic phenomenon by using self made cloud and mist cabinet in order to make observations and research .

采用随机键，将连续的粒子位置向量转化为离散的解向量，并通过提出相对最短距离法来评价解集的优劣。

The random key was adopted to change from continuous particle position vectors to discrete solution vectors . And the method of relatively minimum distance was proposed to evaluate the Pareto muster .
