It means that, in information terms, the signal pattern is determined by the way the voltage varies with time, and ideally the current required is then drawn.

用信息术语来说就是信号类型取决于电压随时间变化的情况，且在理想情况下就能吸收所需的电流。

Their idealised version of this question was to ask how two signal chemicals, starting from opposite ends of an embryo, could result in a pattern that looked like the French flag (ie, three different coloured vertical stripes).
