摘要：

Model of separate spectral lines composing EPR-spectra of tooth enamel can be described with fine accuracy by integral of convolution of three distribution functions: Lorenzian, Gaussian and anisotropy. Simulation of spectra was done by the method of optimisation of non-linear parameters combined with the Gauss method of exclusion for linear parameters to obtain the minimum of the sum of the squares of the differences between the experimental EPR-spectrum and its model. The final result was the deconvolution of complex EPR-spectrum into its components (the background and radiation-induced signals) with the following reconstruction of the individual absorbed dose.
