''Industrial uses of liquid nitrogen
''
dd dd dd dh :m ''In industrial production, compressed liquid air is used Liquid nitrogen is obtained by fractionation and can be used as a deep refrigerant. Due to its chemical inertness, it can directly contact biological tissue and freeze immediately without destroying biological activity, so it can be used

''Cryotherapy Liquid nitrogen cryotherapy is a new technology in the field of modern therapeutics.
''
dd dd dd dh :m ''Liquid nitrogen cryotherapy is a comprehensive effect of cryobiology. Normal cells will undergo irreversible damage in an extremely frozen state. It uses extreme freezing to quickly kill cells in the diseased area, allowing the diseased area to recover normally. It is generally used to treat warts, corns and skin diseases.
