Made an appreciation of measurements errors in method of proton magnetic resonance relaxation (PMRR) for receiving of values of spin-spin relaxation times Т2i and corresponding them values А2i, of relative amplitudes of spin-echo envelope. Estimatesof opportunities of reverse Laplace transformation (L-1) algorithm realized in UpenWin program for relaxation times spectra determination, minimization of errors and facilitation for interpretation received data of kinetic curve PMRR relaxation process.
