1. dual的解释

1. 对偶：就数学原理,超密加码与量子隐传是两个互为对偶(dual)的概念. 首先假设春娇(Alice)与志明(Bob)是一对相隔甚远的恋人,春娇想把手边的一个单一量子位元「隐形传递」给志明当礼物. 但春娇完全不知道此位元处於何型式的量子态,

2. 对偶的：1635 年笛卡尔 (Rene Descartes) 观察到雪花结晶的为对偶的 (dual) 正多面体, 例如正八面体与正六面体互为对偶, 正二十面体与正十二面动还不是很明白时, 刻卜勒 (Johannes Kepler) 就用模型来说明行星的运动.

3. 二重的：自我意识,乃高于意识,乃是三重的(trinal),而意识乃为二重的(dual). 同一个人的灵乃有两种不同的形式--主体与客体. 上帝三种本质的意识,结合起来,成为一体的时候,就形成一个上帝的意识,......三个位格,便成为一个本体」.
