| 释义 | > as lemmasStirling (or †Stirling's) engine Stirling (or †Stirling's) cycle, the thermodynamic cycle on which an ideal Stirling engine would operate, consisting of an isothermal expansion, a drop in temperature at constant volume by giving up heat to a regenerator, an isothermal compression, and an increase in temperature at constant volume by gaining heat from the regenerator; Stirling (or †Stirling's) engine, originally, an external-combustion air engine invented by Stirling ( Brit. Pat. 4081 (1816)); more widely, a mechanical device used to provide either power or refrigeration and operating on a closed regenerative cycle, the working fluid being cyclically compressed and expanded at different temperatures; also elliptical as Stirling.

Civil Engineers 4 359 In Mr. Stirling's engine the intense heat of the fire did not come into actual contact with the pistons. 1887 Encycl. Brit. XXII. 523/1 Stirling's cycle is theoretically perfect whatever the density of the working air. 1889 C. H. Peabody Thermodynamics of Steam-engine xi. 174 A recent hot-air engine made on the same principle as Stirling's hot-air engine. 1943 E. H. Lewitt Thermodynamics Applied to Heat Engines (ed. 3) iii. 57 The Stirling cycle is thermodynamically reversible owing to the action of the regenerator. 1963 Engineer CCXIV. 1063/1 A Stirling cycle machine operates on a closed regenerative thermodynamic cycle. 1973 Sci. Amer. Aug. 81/2 In practice Stirling engines do not work on the Stirling cycle. It is not possible to have isothermal (constant temperature) compression and expansion processes. 1980 Times 16 Oct. (Internat. Motor Show Suppl.) p. xiv/8 Most of the technology of the Stirling has been established since the Second World War,..but mainly for vehicle and industrial duties rather than aircraft. < as lemmas |
