Compensation effect resulting from the use of mechanistic equations, and its physical significance

A compensation effect is observed in the activation parameters resulting from various mechanistic equations; theT computed from the slope of theE*vs InA plot matches the observed DTG peak.

Bei den sich aus Gleichungen für verschiedene Mechanismen ergebenden Aktivierungsparametern wurde ein Kompensationseffekt beobachtet; der aus der Neigung der GeradenE* gegen InA berechneteT-Wert stimmt mit der Lage des beobachteten DTG-Peaks überein.


Компенсационный эфф ект проявлялся в активационных парам етрах, полученных на основе различных мех анистических уравне ний. ВеличиныТ, вычисленные из нак лона графической зависим остиЕ*-lnA, хорошо согла суются с наблюдаетмыми пика ми ДТГ.
