They discussed an application structure with two layers: the bottom layer is made up of functional components, while the top consists of the flow logic of the application.

他们讨论了一个有两层的应用程序结构：底层由一些功能组件组成，上层则由应用程序的流逻辑组成。

They work by applying a current to two layers of semiconductor, which creates a flow of electrons and releases energy in the form of light.

它们通过对在半导体的两表层上通上电流后运行，这样既形成连续不断的电子也释放了光形式的电能。

The Sun's changeable magnetic field is generated at the boundary between these two layers, where strong electric currents flow.

When the two layers' polarity faces the same direction, electrons flow readily through the barrier, and the chip reads a one.
