英语词汇“effective temperature”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

effective temperature n. (a) Physics the temperature of the sun or other astronomical body, estimated as the actual temperature of a black body of the same size which would radiate the same amount of energy; (b) the temperature at which something is effective or functional; (c) the subjective degree of heat or cold, taking actual temperature and other environmental factors into account; (d) Physics the temperature of something as represented by the kinetic energy of its constituent atomic or subatomic particles.

1880 C. A. Young in Princeton Rev. Jan. 94 We may..inquire what must be the temperature of a globe of the sun's size..and at the sun's distance from the earth, in order to send us the amount of heat actually observed. Assuming the radiating power of this fictitious sun to be the same as that of a surface of lamp-black (the best radiator known), the temperature corresponding to this assumption is designated as the sun's effective temperature.

1924 H. Dingle Mod. Astrophysics ix. 119 The wavelength of maximum energy, from which the effective temperature is determined.

1929 R. A. Wardle Princ. Appl. Zool. 197 There would seem to be for each species of insect a range of temperatures between whose maximum and minimum extremes the insect is active... This range of temperatures may be termed the range of Effective Temperatures.

1930 Engineering 28 Nov. 671/1 The effective temperature of a room, that is to say, the temperature at which, in still air, a sizeable black body at standard temperature will lose heat at the same rate as it is being lost in its environment.

1957 Encycl. Brit. XVII. 847 f/2 The term ‘effective temperature’ was sometimes used to denote what we now call ‘colour temperature’. ‘Effective temperature’ is now used to denote the temperature of a black body for which the total emitted radiation..is the same as the total radiation..emitted from the surface of a star.

1976 O. Ojo in C. G. Knight & J. L. Newman Contemp. Afr. viii. 104 The Effective Temperature index (ET)..was developed by exposing volunteer subjects to different atmospheric conditions of temperature, humidity, and air movement and by asking them to rate their comparative sensations of warmth or coolness.

1976 Philos. Trans. (Royal Soc.) A. 281 513 The effective temperature of the plasma turbulence is many orders of magnitude larger than the initial electron temperature.

2002 F. Close et al. Particle Odyssey x. 204 When individual electrons and positrons collide at energies at 100 GeV, the effective temperature is some 10¹⁵ degrees.
