《论摩擦激起的热源》[1]（英語：An Experimental Enquiry Concerning the Source of the Heat which is Excited by Friction[2]，也称为伦福德的炮筒镗孔摩擦生热实验[3]）（1798），是由伦福德最早发表在《自然科学会报》[4] 上的一篇论文，这篇论文向当时的热质理论抛出了一个重大难题，并引发了19世纪的热力学革命。

^From p. 100 of Rumford's paper of 1798: "Before I finish this paper, I would beg leave to observe, that although, in treating the subject I have endeavoured to investigate, I have made no mention of the names of those who have gone over the same ground before me, nor of the success of their labours; this omission has not been owing to any want of respect for my predecessors, but was merely to avoid prolixity, and to be more at liberty to pursue, without interruption, the natural train of my own ideas."
^In his Novum Organum (1620), Francis Bacon concludes that heat is the motion of the particles composing matter. In Francis Bacon, Novum Organum (London, England: William Pickering, 1850), from page 164: （页面存档备份，存于互联网档案馆） " … Heat appears to be Motion." From p. 165: （页面存档备份，存于互联网档案馆） " … the very essence of Heat, or the Substantial self of Heat, is motion and nothing else, … " From p. 168: （页面存档备份，存于互联网档案馆） " … Heat is not a uniform Expansive Motion of the whole, but of the small particles of the body; … "
^"Of the mechanical origin of heat and cold" in: Robert Boyle, Experiments, Notes, &c. About the Mechanical Origine or Production of Divers Particular Qualities: … (London, England: E. Flesher (printer), 1675). At the conclusion of Experiment VI, Boyle notes that if a nail is driven completely into a piece of wood, then further blows with the hammer cause it to become hot as the hammer's force is transformed into random motion of the nail's atoms. From pp. 61-62: " … the impulse given by the stroke, being unable either to drive the nail further on, or destroy its interness [i.e., entireness, integrity], must be spent in making various vehement and intestine commotion of the parts among themselves, and in such an one we formerly observed the nature of heat to consist."

From page 116: （页面存档备份，存于互联网档案馆） "Now Heat, as I shall afterward prove, is nothing but the internal Motion of the Particles of [a] Body; and the hotter a Body is, the more violently are the Particles moved, … "
^Sometime during the period 1698-1704, John Locke wrote his book Elements of Natural Philosophy, which was first published in 1720: John Locke with Pierre Des Maizeaux, ed., A Collection of Several Pieces of Mr. John Locke, Never Before Printed, Or Not Extant in His Works (London, England: R. Francklin, 1720). From p. 224: （页面存档备份，存于互联网档案馆） "Heat, is a very brisk agitation of the insensible parts of the object, which produces in us that sensation, from whence we denominate the object hot: so what in our sensation is heat, in the object is nothing but motion. This appears by the way, whereby heat is produc'd: for we see that the rubbing of a brass-nail upon a board, will make it very hot; and the axle-trees of carts and coaches are often hot, and sometimes to a degree, that it sets them on fire, by rubbing of the nave of the wheel upon it."

From the footnote continued on p. 313: （页面存档备份，存于互联网档案馆） " … I think Sir Isaac Newton's opinion, that heat consists in the internal motion of the particles of bodies, much the most probable … "
