Experimentally studies the relation of the pressure difference and leakage rate of contaminations separately by atmospheric dust method and experimental culture method. The results show that the leakage concentration ratio of contaminations decreases about 0.03 when the pressure difference changes from 0 to -6 Pa and that the leakage concentration ratio almost keep the same value whe...
