Laser photo-ionization spectrometry was found to be a highly sensitive method for detecting photon-absorbing molecules.
激光光电离光谱(L PIS)是一种高灵敏度的分析方法。

On the basis of the experiments, it has been proved that the ionization mechanism of the detector is the collision ionization rather than the photo-ionization.
从实验上证明，这种检测器的离子化机理是碰撞离子化而不是光离子化。

It is show that, for the ultraviolet pre-ionization TEA CO2 Laser, the absorption of two photos in the process of the photo-ionization plays an important role.
