Fick|fɪk| The name of A. E. Fick (1829–1901), German physiologist, used attrib. or in the possessive to designate a method of determining cardiac output introduced by him, as Fick method, Fick('s) principle, and also a law of diffusion enunciated by him and the equation expressing it, as Fick('s) equation, Fick's law. Hence ˈFickian a.
1895C. S. Palmer tr. Nernst's Theoret. Chem. i. v. 144 A complete mathematical description of the process of diffusion..was..restated by Fick, who subjected it to a thorough theoretical and experimental proof... Fick's law has nothing to say concerning the nature of the mechanical force: it is simply the ‘nature of the case’. 1919Jrnl. Physiol. LIII. 420 The circulation rate determinations after Fick's principle should be improved. 1957G. E. Hutchinson Treat. Limnol. I. v. 254 Equations of the form of equations 11 and 12 are comparable to that expressing passage of a diffusing solute in an undisturbed liquid according to Fick's law; such equations are therefore commonly called Fickian. 1966Schultze & Heremans Molec. Biol. Human Proteins I. iv. i. 620 It is easy to grasp the reason why the diffusion co⁓efficient occurs in Fick's equation. 1968Kitchin & Julian in Passmore & Robson Compan. Med. Studies I. xxviii. 28 The disadvantages of the Fick method. Ibid. 29 The advantage of the Fick principle is its simplicity. It is essentially a dilution method, but has none of the problems of recirculation involved in most dilution methods using exogenous indicators. |
