| 释义 | > as lemmasMaxwell's equation Maxwell's equation n. (also Maxwell equation) each of a set of four linear partial differential equations which summarize the classical properties of the electromagnetic field and relate space and time derivatives of the electric and magnetic field vectors, the electric displacement vector, and the magnetic induction vector, and also involve the electric current and charge densities; now usually in plural.Maxwell published eight equations of the electromagnetic field on pp. 480–6 of his paper ‘A Dynamical Theory of the Electromagnetic Field’ ( Philos. Trans. Royal Soc. (1865) 155 459–512). But the four equations now known as Maxwell's equations owe their form to O. Heaviside. Heaviside published them as a more useful and compact set of Maxwell's eight equations in a series of papers published in the Electrician in 1885, specifically in the issues of 21 Feb., 14 Mar., and 12 June (republished in his collected Electr. Papers (1892) I: see pp. 447, 452, and 475).extracted from Maxwelln.2< as lemmas |
