First, the critical discharge coefficient formula of the effervescent atomization and the penetration correlation for the pressure atomization were constructed.

The present study shows that there is a critical seal pressure which is only related to the compression ratio and the friction coefficient, but does not depend on the radius of the elastomer ring.

分析结果表明，临界密封压力只与橡胶圈的压缩量和密封面摩擦系数有关，与橡胶圈截面半径无关。

The result shows that the permeability coefficient will increase gradually with the pressure increase and drastically after the strain gets to a critical value, when the fissure will occur.

结果表明，随着压力增加，渗透系数逐渐增大，在应变达到某临界值后，渗透系数开始急剧增大，此时裂隙产生。
