1. 天王、海王、冥王：Uranus (希腊神话中的天神乌拉诺斯), Neptune (尼普顿, 相当于希腊神话中的波塞冬：Poseidon), Pluto (普路托, 相当于希腊神话中的哈得斯：Hades).
2. 天王星、海王星、冥王星：Uranus, Neptune, Pluto (距离太阳最远的三颗行星，由近及远依次为：天、海、冥).
3. 三种相邻的放射性元素(92-94号元素)，铀、镎、钚：Uranium, Neptunium, plutonium.
4. 很显然，这三颗相邻的行星、这三种相邻的放射性元素，按照类比的规则有规律地使用了三个神仙的名字来命名。
5. 因为海王星、冥王星在天王星之后紧邻天王星，同样地，镎、钚在铀之后紧邻铀元素，所以就是采用这种对应关系来命名了，非常具有统一性和一致性。
6. 铀、镎、钚：谐音“又拿布”----又把布拿来。
plutonium 钚来自Pluto,冥王，冥王星，-ium,金属元素。因该金属元素元素周期位于neptunium（Neptune,海王星）之后而命名。
