Within the DRT function, each peak signifies a distinct physicochemical process, with the area under the peak indicating its corresponding resistance. The calculation of the DRT function, represented as g(f), poses an ill-posed mathematical problem, necessitating the careful selection of a regularization parameter (lambda) to derive meaningful results. An improperly chosen regularization parameter may induce oscillations, false peaks, or merge multiple processes into a singular peak. Thus, the selection of lambda is crucial for obtaining accurate and reliable outcomes.
