The variations of the critical frequency of F
2 layer (f
0F
2) and the HFinterference centroid frequency (ICF) at Guangzhou and Haikou during the solar eclipseoccurring on Oct. 24, 1995, are presented. The morphology of f
0F
2 for two differentstations is not completely same for the same solar eclipse; the mophology of thesame station is not completely same duing the different solar eclipse; and ICF isnot as lower as Predicted. So, it is thought that dynamics may play a more important role in low latitude region than photochemistry related directly to the solarradiation.
