这个技术是将氧化钛作为一层置于电子释放和流动的两个区域间。

The trick is to put the titanium oxide in as a layer between the part of the cell where the electrons are liberated and the part where they are collected for dispatch into the wider world.

为了释放电子，必须使电子高速旋转而足以摆脱它们的原子核。

To free electrons, something has to make them whirl fast enough to break away from their nuclei.

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。

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.

Now, if this incident energy is great enough it will take an electron out of the ground state and promote it.

现在，如果入射能足够的话,它会将一个电子从基态中释放出来,并且加速它。

We're going to release a lot of energy for bonding, it's going to more than make up for the fact that we actually had to spend some energy to promote that electron.

在成键时，会释放大量能量,这比补偿激发电子,的能量要多。
