✦ Synopsis


A straight line relationship is shown between the heat of activation of a relaxation process and the temperature at which the maximum relaxation occurs. The utility of this relationship is pointed out as being the following: (1) a quick way of finding the heat of activation from a single measurement, (2) a means of helping to locate the position of a relaxation peak if its activation energy is known roughly from some other measurement, (3) an aid in analyzing mathematically the factors which describe a given phenomena. UNE NOUVELLE METHODE POUR LA DETERMINATION DE LA CHALEUR D'ACTIVATION DANS LES PROCESSUS DE RELAXATION 11 est montre, qu'une relation lineaire existe entre la chaleur d'activation du processus de relaxation et la temperature B laquelle a lieu le maximum de relaxation. L'utilite de cette relation est due au fait qu'elle fournit: (1) un moyen rapide de trouver la chaleur d'activation d'apres une seule mesure, (2) un moyen de localiser la position d'un maximum de relaxation, si son energie d'activation est connue approximativement comme resultat de quelque autre mesure, (3) une aide dans I'analyse mathkmatique des facteurs qui decrivent un phenomene don& EINE NEUE METHODE ZUR BESTIMMUNG DER AKTIVIERUNGSWARME VON RELAXATIONSVORGANGEN Es wird gezeigt, dass ein linearer Zusammenhang zwischen der Aktivierungswarme eines Relaxationsvorganges und der Temperatur, bei der dieser Vorgang von statten geht, besteht. Der praktische Wert dieser Beziehung besteht in folgendem: Sie gibt (1) einen schnellen Weg, die Aktivierungswarme aus einer einzieen Messune zu ermitteln. (2) eine Methode. die Laze eines Relaxationsmaximums zu finden, wenn dUer ungefahg Wert der Akt'ivierungsenergie aus and&en Messungen bekannt ist, und (3) ein Hilfsmittel. die verschiedenen Faktoren, die einen bestimmten Effekt ausmachen, mathematisch zu analysieren.

## Abstract This paper addresses the development of the DXDR method by introducing a modified fictitious time (MFT) increment. The MFT is determined by minimizing the residual force after each iteration. The rank of the convergence rate shows the advantage of the new method. The results obtained fr
