Abstract：
A method to solving a few practical problems in analysing lifetime spectrum is searched through analysis of the lifetime specrtra of e⁺ annihilation in amorphous alloy samples and other ones. It includes the selection of the starting point of fitting data one by one above a certain time range on the right of the spectrum peak, the normolazation of the sum of relative intensities of the lifetime components by adjusting the zero time position, and finally testing the tail component to diminish the effect on analysis of the end position of the fitting data.
