“Dewar flask”的概念、定义、翻译、参考文献-科学参考

Dewar flask

Physics

A vessel for storing hot or cold liquids so that they maintain their temperature independently of the surroundings. Heat transfer to the surroundings is reduced to a minimum: the walls of the vessel consist of two thin layers of glass (or, in large vessels, steel) separated by a vacuum to reduce conduction and convection; the inner surface of a glass vessel is silvered to reduce radiation; and the vessel is stoppered to prevent evaporation. It was devised around 1872 by Sir James Dewar and is also known by its first trade name Thermos flask. See also cryostat.

Chemical Engineering

A container used for storing hot or cold liquids that are able to maintain their temperature independently from their surroundings. The heat loss is kept to a minimum by using a container held within a container separated by a vacuum. The thin walls of the inner container are made of glass (or steel in the case of bigger containers). The inner surface of the glass vessel is silvered to reduce loss through radiation. It was devised around 1872 by Sir James Dewar, and is also known by its trade name Thermos flask.
