摘要：

An advantageous algorithm is proposed for correcting the Doyle approximation for the popular Ozawa-Flynn-Wall analysis to make a model-free evaluation of the activation energy from a series of non-isothermal measurements carried out at different heating rates. In this way a definite improvement in the corrective factor is reached by an approximation formula. The maximum approximation error is 3 x 10(-4). Evidence concerning this new variant is provided by means of simulated data.
