courbe d'isovaleur

CONT: Vertical Mapper : visualise un phénomène en continu sur une zone, sous forme de courbes d'isovaleurs, planes ou en relief,

CONT: ... the determination of the ""optimal period of production"" means something different for Wicksell. ... Thus, for a given r and earnings per period X (= V[subscript 0]) we can draw out a curve V[subscript 0]e[exponent rt] which can be conceived as an ""isovalue"" curve, i.e. a series of combinations of V[subscript 0]e[exponent rt] and t which yield the same present value V[subscript 0]. As time increases, total earnings increase so that V[subscript 0]e[exponent rt] increases. Thus, the isovalue curve is upward sloping and convex.
PHR: Isovalue curve of temperature.
