3, the bulb filled with nitrogen can prolong the service life

4, food packaging filled with nitrogen to prevent decay

5, medical treatment can be performed under the condition of liquid nitrogen freezing anesthesia

6. Superconducting materials show superconducting performance in the low temperature environment of liquid nitrogen
