Abstract：
On the basis of one simple grain boundary model,the trapped states of positrons at grain beunaries in pure Aluminium are solved and the corresponding positron annihilation lifetime spectra are calculated.The correlations between the atomic density distributions of grain boundaries and the lifetime spectra are discussedand the existing experimental results are explained theoretically.
