1·Water can be reduced to oxygen and hydrogen by electrolysis.
水通过电解可以分解为氧和氢。
2·Though galvanisation is often done by dipping steel in liquid zinc, it is sometimes done by electrolysis—nickel and copper plating are normally done this way.
尽管一般是通过液态锌蘸洗钢铁来镀锌，有时候也会用电解的方法，在电镀镍和铜时就通常使用电镀。
3·Hydrogen can also be created from water using electrolysis and potentially even from biofuels.
氢也可以通过电解水产生，甚至可能从生物燃料中获取。
4·We can drink it, grow food with it and breathe it - by separating the oxygen from the hydrogen through a process called electrolysis.
这样，我们可以喝上水，种植粮食，和呼吸空气——利用电解，分离出氢气和氧气。
5·Technical advances included electrolysis, the ship’s chronometer, chemical processing, tool-making machines, and the water frame.
技术进步包括电解、船上的精密计时器、化学反应、机床和水力纺纱机等等。
