A spectre consisting of utmost six peaks with alognormal distribution in relaxation tabs and an exponential background could be fitted by theprogram. Upon this program, the relaxation paramaters of bamboo grain boundary peak inpure Al are analyzed quantitatively. It shows that the relaxation strength decreases with thedescending of peak temperature.
