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