当一个体积为 1 m³ 的密闭、抽空的容器内的压力每秒上升 1 Pa 或者在过压的情况下每秒下降 1 Pa 时，给出的泄漏率 QL = 1 Pa-m³/s。
A leakage rate of QL = 1 Pa-m³/s is given when the pressure in a closed, evacuated container with a volume of 1 m³ rises by 1 Pa per second or when the pressure in the container drops by 1 Pa in the event of overpressure.
