photodissociation

Different photodissociation spectra, the action spectrum as function of laser wavelength, and ratio curve of different channels were obtained.

得到了反应的光解谱和作为波长函数的光解行为光谱以及各反应通道的分支比。

The oxygen in the atmosphere had to come from another source. The likely possibility involves the photodissociation of water vapor by high energy rays from the sun.

大气中的氧气必须从其它途径获取，很可能是光解作用，即由太阳反射的高能射线分解水蒸汽。
