The relationships between the solar activities and a great amount of O_3 data have been analysed in more detail. We find that there are "sensitive areas" and "non-sensitive areas" existing in the total ozone responding to the influence of the 11- year solar cycle. Especially, the responses are stronger in the higher latitudes and the winter- spring period than that in the lower latitudes and the summer- autumn period. Accordingly, in addition to the Chapman process, which is the main one, there should be a secondary process for controlling the stratospheric ozone layer. Therefore, we also present a new viewpoint of the formation of the Antarctic ozone hole and predict its trend in the future years.
