1854 Rankine in Philos. Trans. (Royal Soc.) 144 i. 128 It is required to find, by the determination of points, a corresponding curve passing through a given point B, such, that the quantity of heat absorbed or emitted by the substance in passing from any given isothermal curve to another, shall be the same, whether the pressures and volumes be regulated according to the original curve, or according to the curve passing through the point B... This curve, and the curve EF, in their relation to each other, may be called Curves of Equal Transmission.]
1859 W. J. M. Rankine Man. Steam Engine (1861) 345 The lines EF and GH have the required property, and are said to be isodiabatic with respect to each other.
