摘要
The experiment result in this article shows that the initial and critical cavitation pressure of pure water are both increasing along with the increase of height above sea level,and the ionization strength of cosmic rays in the lower aerosphere is the crucial factor which influences the cavitation pressure of pure water.The author concludes the relationship between the cavitaion pressure of pure water and the height above sea level.Moreover,air particles in water caused by the radiation of cosmic rays can exist in the water for a long time and will not escape.
