The calculated results show that the electron current injected into the base region is not affected, but an increase of the base hole current is increased with the lifetime reduction.

计算结果表明，发射区载流子寿命的变化几乎不影响注入到基区的电子电流，但却成反比例地影响基区空穴电流。

Electrons and holes injected into the polymer film form bound states called excitons that break down under electrical current, emitting light as they do so.

电子和空穴注入高分子膜所形成的界态称为电子空穴对，电子空穴对冲破电流的阻碍，于是便产生了光。

In the current trials, it was injected once a week for five weeks--a much more difficult prospect than taking a pill.
