Beschreibung
Zusammenfassung:	The invention discloses a method for measuring the leakage rate of a containment vessel, and the method comprises the steps: charging gas into the containment vessel, so as to enable the pressure in the containment vessel to reach a preset test pressure; monitoring the real-time pressure in the containment vessel, supplementing gas into the containment vessel according to the monitoring result of the real-time pressure in the containment vessel so as to maintain the real-time pressure in the containment vessel to be equal to the preset test pressure, and detecting the flow of the gas supplemented into the containment vessel so as to determine the measured volume leakage rate; monitoring the temperature and/or humidity in the containment, and determining a compensation leakage rate according to the monitoring result of the temperature and/or humidity in the containment; and determining the containment leakage rate according to the measurement volume leakage rate and the compensation leakage rate.
