title: [Ratio of heat loss in a polyphasic system].
abstract: The relative thermal differential (dtr) is proposed as a predictor for the thermal loss rate in a polyphasic system. The dtr enables one to predict the thermophoric element temperature in a closed system. Simplied grids for the calculation of linear equations and their correlation coefficients are presented.
