Methodological features of an investigation of the defect structure of technically important materials by using positron annihilation are discussed. It is shown that the important annihilation parameters characterizing the positron-sensitive defects are the mean positron lifetime τ, the width of the annihilation photon correlation curves (APCC) at half the height Γ and the APCC form parameter f, and the linear Doppler broadening parameter of the annihilation γ-line S.
