摘要： 在高压密封系统中，漏率与压力的关系，目前仍然处于探索之中。对不同的刚性物理漏孔进行了不同压力状态下的漏率试验，发现了漏率的函数关系。在试验的基础上，经理论分析，验证了其规律的正确性。同时，发现随着漏孔长度的减少而压力指数变大的规律。

Abstract: A relationship between leak rate and pressure in a seald system at high pressure is studies.In this paper,the theoretical analysis and the leaking experiment are presented.The experiment was accomplished with various physical leaking holes at varied pressure.The experimental results show that the relationship is correct and the exponent of the gas pressure increases with the decreasing length of leaking hole.
