束缚原子不同于自由原子之处，是束缚原子考虑了在不同分子中电子云的不同重叠，将计算结果与实验及其它计算结果进行了比较。

The difference between bonded atom and the free one in state is that the overlap of electron cloud of bonded atoms in a molecule is considered.

这个神秘而完全不可解释的性质使伊壁鸠鲁主张人类的自由意志以对抗早期原子论的批评家们。

This mysterious and wholly unaccounted for property allowed Epicurus to maintain a concept of human free will against the critics of earlier atomic theories.

他同时是一位宣扬谨慎和节制的快乐主义者，一位反对神的介入以及灵魂生存的有神论者，并且是一位同时抱有机械主义与自由意志的原子论者。

He is at once a hedonist who preaches prudence and temperance, a theist who rejects divine intervention and the survival of the soul, and an atomist who upholds both mechanism and free will.

When it breaks this bond, that chlorine atom, a free chlorine atom comes down and reacts, this is ozone, with the ozone in the upper atmosphere.

当它打破这个化学键，氯原子，一个自由的氯原子下来,和在大气层的上方的臭氧反应，这就是臭氧，在大气上层有臭氧。

This should make sense, because if an atom has a very high electron affinity, that means it's really happy taking an electron from another atom, or taking a free electron -- that that's very favorable.

这应该是合理的，因为如果一个原子有很高的电子亲和能，这意味着,它非常乐意从另外一个原子那里夺取一个电子，或者得到一个自由电子--这是非常利于发生的。
