如果仅从分散性的角度考虑，那么应该是分散性更好的SiO2PI复合材料获

If only from the perspective of dispersibility, the SiO2PI composite material with better dispersibility should obtain better antiprotonic oxygen performance, and as the silicon oxide in the composition decreases and the alumina increases, the antiprotonic oxygen corrosion performance should gradually decrease . This is inconsistent with the experimental results.

If only from the perspective of dispersion, then it should be better dispersion of SiO2PI composite materials to obtain better anti-atomic oxygen performance, and as the components of silicon oxide reduction of alumina increase, anti-atomic oxygen corrosion performance should gradually decline. This is not consistent with the results of the experiment.
