求翻译：可能有两个原因，一是光催化氧化对HIA组分的降解作用本身就不显著；二是由于HIA在降解的同时又通过其他组分的光催化转化得到补充。是什么意思？

There may be two reasons, first, photocatalytic oxidation degradation of components of the HIA is not in itself significant; second is due to the degradation of the HIA also through other components of the catalytic conversion of light to be added.

There are two reasons for this, and the other is light-catalyzed oxidation of HIA Group divided by itself does not significantly degrade role; 2 HIA biodegradation is due at the time of adoption of the other group is the additional optical catalytic converters.

Possibly has two reasons, one is the photochemical catalysis oxidation affects to the HIA component degeneration itself is not remarkable; Two is because HIA also obtains the supplement during degeneration through other component photochemical catalysis transformation.

There may be two reasons, first, photocatalytic oxidation degradation effect on HIA component itself is not significant; the second is due to HIA in degradation and supplemented by other components of light catalytic converter.
