摘要
The invention concerns the study of the effect of a supercritical fluid on the transitions of a material, which consists in varying continuously or by stages according to a predetermined programme, a first parameter value selected among the super-critical fluid pressure, the temperature of a cell containing the material sample and said sample volume, while maintaining a second of said parameters at a value selected, so as to induce the transition; and in recording the variation of the first parameter, that of the third parameter and the heat flow rate in the cell; in comparing said recordings with those obtained by replacing the supercritical fluid with a neutral fluid. The figure shows a diagram of the device for carrying out said study. The invention is in particular useful for studying a polymer material transitions.
