Using votis electric pile he discovered how to use an electric current to break down various materials into their separate elements . 他用伏打电池发现通电可将各种物质分解成单质元素。
the potential of the actual cell, ae°, can then be regarded as the algebraic sum of the two half-cell potentials. 实际电池的电势AE可看作两个半电池电势的代数和。
Adjacent batteries must be spaced closer than the strip length so that there is always spring-bow tension in the strip . 相邻电池的间隔要小于铜条长度，以保证在铜条上总有弯曲的张力存在。
Methods based on electrometric measurements involving a galvanic cell may be utilized to determine the oxygen content of a gas . 以电测法（包括原电池）为基础的方法可以用来测定气体的含氧量。
In general, there is a measurable difference in potential between the two electrodes whether the cell is passing a current or not . 通常，无论电池有无电流流过，两电极之间均具有可测量的电势差。
We can only measure the difference between the potentials of two half cells when they are linked to form an electrochemical cell . 当两个半电池连接形成一个化学电池时，我们仅能测定两个半电池之间电位的差值。
