3 Terms and definitions
GB/T 17446 defined and the following terms and definitions apply to this document.
3.1
Experiment cabinet experimentrack
Under the constraints of the flight platform resources, there is a unified interface of machine, electricity, and heat, which is suitable for supporting different disciplines to carry out different experimental tasks
With technical facilities.
Example. International Standard Payload Enclosure (ISPR) on the ISS.
[GB/T 30114.1-2013, Definition 4.7]
3.2
Quick change connector quickdisconnectcouplings
Self-sealing structural components for gas/liquid line head/seat can be quickly connected or disconnected without any universal or special tools.
3.3
Dropping volume spilage
Under certain pressure, the quick-release connector breaks the volume of liquid that overflows from the inside out each time.
3.4
Leakage rate
Leakage per second pressure of 1Pa, the temperature is 20 ℃ cubic meters of air.
