During the course of the testing, activeelectron-emission substances from the cathode were deposited continuously onto the surface of the grid.
在测试过程中活性的电子发射物质源源不断地从阴极沉积到阴极表面。

For example, one layer contains the active material that releases an electron when it's struck by light and another layer contains the circuit that carries the current.
例如,放置活化材料的一层,当它被光照时,便会释放电子,而电路层则负责传送电子流。

Electron transfer reaction, one of the forward questions in chemical researches a very active domain in natural science in recent years.
