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

c. inert gas: (a) As an ordinary use of the adjective with gas: any gas that is (relatively) inert. (b) Usually as (the) inert gases (now apprehended as a special collocation, analogous to the terms alkaline earths and rare earths): any of the elements of group o of the periodic table, viz. helium, neon, argon, krypton, xenon, and radon, all of which are colourless, odourless, and tasteless gases which were formerly thought to be completely unreactive chemically, forming no compounds (though compounds of some of the gases are now known). Cf. noble gas n. and adj.

inert gas1885

(a)

1885 W. Macgregor Gas Engines v. 127 Nitrogen retards the combustion of hydrogen and that of carbonic oxide... The inert gas at the same time lowers the temperature of combustion.

1911 Encycl. Brit. XIX. 715/1 Nitrogen is a very inert gas: it will neither burn nor support the combustion of ordinary combustibles.

1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) V. 553/2 The gas contains about 27% carbon monoxide and over 70% of inert gases (CO₂ and N₂), giving it the lowest heating value..of any of the commercially used fuel gases.

1973 Sci. Amer. Dec. 22/3 The flywheel and the generator-motor would operate in an atmosphere of inert gas (hydrogen or helium).

1898 W. Crookes in Proc. Royal Soc. 63 411 Professor Ramsay and Mr. Travers have discovered two other inert gases accompanying argon in the atmosphere. These are called Neon and Metargon.] (b)1902 G. S. Newth Text-bk. Inorg. Chem. (ed. 9) ii. iv. 232 This property of nitrogen of uniting directly with magnesium was utilised in effecting the separation of the nitrogen of the air from the small quantities of argon and other ‘inert gases’ contained in the atmosphere.1927 J. W. Mellor Comprehensive Treat. Inorg. & Theoret. Chem. VII. xlviii. 906 The five gases—helium, neon, argon, krypton, and xenon—are colourless, and without odour. They are chemically indifferent and are hence called the inert gases or the rare gases, or the noble gases of the atm.1939 H. J. Reich Theory & Applic. Electron Tubes xi. 396 An external electrode may also be used to initiate breakdown of a mercury pool tube containing a small amount of inert gas.1950 N. V. Sidgwick Chem. Elements I. 10 Apart from the molecular ions occurring in the gas, there is in no case satisfactory evidence of the existence of chemical compounds of any of the inert gases.1961 G. A. Cook Argon, Helium & Rare Gases I. i. 1 Unlike the atoms of oxygen, nitrogen, and some of the common gaseous elements, the atoms of the inert gases do not combine to form stable diatomic molecules.1962 Proc. Chem. Soc. 218/2 Although inert-gas clathrates have been described, this compound [sc. xenon hexafluoroplatinate (v), Xe⁺[PtF₆]⁻] is believed to be the first xenon charge-transfer compound which is stable at room temperatures.
