Abstract

The problems of the adequate description of a heterogeneous process are considered by using the methodology of formal nonisothermal kinetics. It is shown that the contradiction between the certainty of the process mechanism and the uncertainty in its description cannot be solved within the traditional methodology of solving the inverse kinetic problem. As an alternative to the traditional methodology based on the principle of unambiguous description, the methodology based on the complementarity principle is suggested. The latter is advantageous to obtain information on the process from the set of its ambiguous solutions.

Zusammenfassung

Die Probleme einer adäquaten Beschreibung heterogener Prozesse werden unter Verwendung der Methodologie der nicht-isothermen Kinetik erörtert. Es wird gezeigt, daß der Widerspruch zwischen der Sicherheit des Prozeßmechanismus und der Unsicherheit in dessen Beschreibung nicht im Rahmen der traditionellen Methodologie zur Lösung inverser kinetischer Probleme gelöst werden kann. Als Alternative zur traditionellen, auf dem Prinzip der eindeutigen Beschreibung beruhenden Methodologie wird eine auf dem Komplementärprinzip basierende vorgeschlagen, die geeignet ist, Informationen über den Prozeß aus einer Reihe von nicht eindeutigen Lösungen zu liefern.

Резюме

С точки зрения методо логии формальной неизотермической ки нетики рассматриваю тся проблемы адекватног о описания гетероген ного процесса. Отмечается, что противоречие между о пределенностью меха низма процесса и неопредел енностью его описани я не может быть разреше но в рамках традицион ной методологии решения обратной кинетическ ой задачи. В качестве аль тернативы традицион ной методологии, основан ной на принципе однозначного описан ия, предлагается мето дология, основанная на принци пе дополнительности. Преимущества послед ней состояет в возмож ности извлечения информац ии о процессе из совокупности его нео днозначных описаний.
