cryotherapy
1. The use of cold in the treatment of disease.
2. Medical treatment that involves cooling the body, especially by applying ice packs.
cryotolerant (adjective), more cryotolerant, most cryotolerant
Relating to the ability to exist in very low temperatures.
cryotrap
To capture one type of gas by entrapping it under another gas during the process of condensing the latter one at a low temperature.
cryotron
1. A cryogenic device that uses the principle that a varying magnetic field can cause the resistance of a superconducting element to change rapidly between its high normal and low superconductive values: used as a switch and as a computer-memory element.
2. A superconductive device in which current in one or more input circuits magnetically controls the superconducting-to-normal transition in one or more output circuits.
cryotropism, cryotropic
An orientation response to the stimulus of cold or frost.
cryoturbation (s) (noun), cryoturbations (pl)
Disturbance of the soil surface by the action of freezing or of alternate freezing and thawing.
