| adiabatic | <radiobiology> Not involving an exchange of heat between the system said to be adiabatic and the rest of the universe. (09 Oct 1997) |
|---|---|
| adiabatic compression | <radiobiology> Compression (of a gas, plasma, etc.) not accompanied by gain or loss of heat from outside the system. For a plasma in a magnetic field, a compression slow enough that the magnetic moment and other adiabatic invariants of the plasma particles may be taken as constant. (09 Oct 1997) |
| adiabatic invariant | <radiobiology> Characteristic parameters which do not change as a physical system slowly evolves, the most commonly used one in plasma physics is the magnetic moment of a charged particle spiraling around a magnetic field line. (09 Oct 1997) |
| adiabatic process | <chemistry> A process in which the system does not exchange heat with the surroundings. (15 Jan 1998) |
