摘要：
In a microwave study a program was designed for thermal regulation. This software allows different types of regulations: P, PI, PD or PID (proportional integration derivation). Results obtained with PID and PI regulation for different previous linear heating schedules (1 deg.s-1 and 0.15 deg.s-1) imposed on a polymer sample (DGEBA/3DCM) up to 280-degrees-C and more are reported. Mathematical resolution of thermal laws applied to the sample permits the regulation constants (T(i), T(d) and G(s)) to be linked to the physical features of the polymer. A method used to calculate: the reflexion constant of the wave on the polymer, rho and the diminution factor, alpha is presented.
